So how is everyone's temp holding up?
 

I went from 81 to 88.9 today. Kind of a big swing!! So how is everyone else doing for temp?

I went from 83 to 87.4 today.. everything looks fine.

Steve

it's a bit cool in my area, i've been between 77 and 79 for the last few days (turned my heaters down to keep me in that area). but my lights will probably bring that up pretty quickly.

Holy Crap....you guys have summer I guess. :eek:

Yea no kidding! 81 to 89 :eek: That's a bid diffrence!
Nothing died or dies with that diffrence in temp?

Jon, everything looks just fine. I increased the fan so I hope to not have that big a swing tomorrow, but ya, summer is here! Normally I go from 81 to about 85 at the end of the day. A 400w in the sump at night doesn't help. Gotta save up for a chiller I guess!!

Ahh it's nice to be in a basement again. Nice and cool down there I tell ya :cool: . But last years heat wave killed of the Xenia (just the Xenia) I was trying to get rid of, so heat waves can be good sometimes :mrgreen: .

It was 32 in the shade at 5 pm today. caught us by surprise.

Steve

Went from 80F to 84F today, so I turned up the speed on the fans today as well.

Hopefully I'll be back down to my normal 80F to 82F swings.

I'm fighting to keep my tank under 88F right now. So far everything looks ok.

mine is down to 86 now. Hopefully I can get it back to 81 by morning. I think the 400w in the sump will stay off tonight.

80-82. Not to bad cause it was 35 today :eek: I'm kinda in a basement and I use 250w halides. I could probably put a fan on the sump if need be. I guess no swing is ideal but Im sure the shallow tropics rise and fall a small amount or no?

i came home to temp of 88f at 11pm at night :(

:eek: Like Deb says, "wholly crap". Boy thats warm. Hard to believe its not hard on the tanks residents. Guess it speaks volumes for keeping ones tank over 80 all year, so the spikes are not a great change to the warmer side.

Being a spoiled oldbrat,It sure is nice having AC. :mrgreen:

I guess that tank temperature is one advantage of living in Northern Alberta. We had to turn on the furnace last night.

Yeah mine shot up from 79 to a whopping 86 yesterday :eek:

I just came home from work and after having the fan blow on the water surface of the sump overnight, the temp has now drpped down to 81.

I'm thinking that maybe I should drill a hole in the side of my roomates small bar freezer, then run a line of my tank water through it to :cool: things down :mrgreen:

cheers, sumpfinfishe

I left home this morning with the temp at 81.2. Hopefully it isn't near 90 again today. I left extra fans on...... :rolleyes:

Man, I just use 250's over my 75 and I'm constantly fighting temps on that tank, and that's with the temperature rarely exceeding 25. Two Icecap fans in the hood, one 8" blowing onto the sump seems to keep it around topping out at 28 or so (I'm using C. I usually convert my temps to F for the benefit of all you antiquidated Fahrenheit folk, but this morning I'm taking a stand and using C!!!!!) Of course three fans over the 72g and three fans for 75 makes for not much except a lot of high blood pressure some days (I love my hobby ... I love my hobby ... I love my hobby.). Mind you some days I'm able to tune out the fan noise. The 20g, with no fan, is topping out at 29.5. These are when the temps outside are in the mid-20's ... I am so screwed if the temps shoot past 30. I might still put some pop bottles filled with water in the freezer, to drop into the sump as a backup plan for those days.

Keeping the window open has helped the daytime temps, but now I have a problem with my one tank DROPPING to about 24 at night. Sigh ... the other two seem to keep up but not this one, I guess I have to actually put a BIGGER heater in there for the summer (what an incredible revelation).

Nope, summer isn't generally a happy time for my tanks. I don't know how everyone else gets away without any fuss. And I'm contemplating a move to 400's this summer .... I wonder if I ought to wait until fall. We'll see.

Icecap fans are nice, but when they step up to 110cfm, they really do sounds like a jet airplance turbine winding up.

Ahhhh, the joys of having one's tanks in the basement, and not fooling around with MH. :eek:

My basement USED to be cold all the time!! The issue for me is having three tanks with halides. It really is too much, and if I felt I could amalgamate the three into two, or one for the matter, believe me I would jump on it. My choices are either to get a rediculously large tank (which due to resources I cannot do while the other three are going, so that realistically is not an option), or to get rid of some things (which I cannot seem to do either because I am too sentimental about things). I keep wondering how to get rid of my 20 because it is serving very little purpose these days, except that there's no room whatsoever in the other two tanks for that carpet. I really don't know what to do. Ultimately, one of those tanks will be coming down ... hopefully before the fall when the energy prices are supposed to skyrocket again. :(

Brad, I probably don't need to tell you this, but keep an eye on those temps, espescially if you have clams. I believe many things can weather an occasional spike like that, but not all will, and espescially not repeatedly. I blame my heat spikes last year (a couple times I forgot to reconnect some fans after doing some work), of course Murphy's Law said those days would be >30C outside, and the tank temps hit 30 (~90F for you antiquidated Fahrenheit folk :razz: ). Although it took more than a month, the clams I had didn't ever look right thereafter and eventually became empty shells. Keep an eye on those temps, k? Maybe add some more fans over the sump if you have to.

Tony, I don't for a second believe that heat had anything to do with the clam issues last summer. My setup was different then and my temp was stable. I lost all my clams after adding a new one. My current setup fluctuates 4 degrees (F) daily since last fall. My clams are fine.

I think the problem yesterday was that although I have a really good fan, I never turn it on. My evaporation hits about 5g a ay if the fan is on. I guess now I need to make more water instead of leaving the fan off. We'll see tonight when I get home if I'm right about that :razz:

my water is staying nice and cool. 79-81

Your circumstances may have been disease, no question. But what I'm saying is that high temps WILL kill clams. Be careful. What harm is there is trying to control heat spikes? BTW I lose way more than 5g per day, you're not getting sympathy from me on that one!! :razz:

Tony, after hearing how they induce spawning in clams, I don't think heat is an issue! But you're right..no harm in keeping things cool.

Adam, you're sounding a bit smug in your basement there. I might sneak by and drop a heater in your room tonight!! hehe

Wow, Now thats some warm water. If everything is healthy and your system has no other issues at the time you'll do ok. The problem is if one other parameter is out you are more likely to have issues. I personally don't like to see my tank over 84. I'd prefer no swing and right now I'm going from 79. to 82 which isn't bad but again don't want much more. I don't think I would want the temps getting very high if you don't run a powerful skimmer or some other sorts of oxygen producing method. You guys with the heat issues noticing a drop in your ph as well? Any ways may the tank Gods be with us through summer as we always have/hear of heat induced deaths this time of year.

Jamie, curious you mention the O2 thing. I didn't notice the fish behaving any differently than normal, so it looks like the O2 wasn't affected (much). I didn't check pH, so I have no idea. Besides, I have no idea what my pH normally is :rolleyes:

mine is holding stead at about 85 - 85..

That's funny because I just turned OFF the gas to my furnace a couple days ago! :eek:

Looks like it's gonna be another scorcher again today! :confused:

Temp is stable at 29. Interesting to note how many people quote their temp in F rather then C.

The simple reason is that my digital thermometer is in F, not C. Now I can convert this if I really need to, but I think everyone understands F just fine. And remember, many of us are old and grew up using Imperial measurements. It's also interesting that the people making noise about F over C report their tank volume in gallons rather than litres (Tony!!) :biggrin:
Others use cups of salt per gallon. Is a cup metric?

I mesure in F for the simple reason that the changes in temp are smaller increment's. And my digital thermomoter is in F as well :lol:

Personaly it comes down to the fact that on my thermometer its in F.... I am not gonan bother trying to convert it :biggrin:

The 90 (upstairs....2x250W MH) has been fluctuating from 79 to 82....until the heat set in a few days ago. Yesterday it went up to 90! I immediately turned off the halides, opened the top and the stand doors. Everything appeared to be fine....so far....

The 54 (downstairs....CF system) only went up to 84....

Maybe some of us are just old and learned in F so we keep to it. :wink:

Steve

Most digital thermometers have a switch that tells it to report in F or report in C. All mine do, and I don't have anything special, just your typical $20-$40 digital thermometer available at any LFS..

I dunno ... it just seemed to me, why the heck do I keep them set at F? Why do I care what the F reading is? I don't say "it is 77degrees outside" I say "it is 25degrees outside" ... so why would I think "golly it is 28degrees outside, therefore my tank might hit 90!!" What doesn't make sense to me is the interchangeable units. Then I thought, well, why bother with F at all? The only reason I've ever reported temps in F in recent years, was so that Americans could understand what I'm saying. Why am I being so considerate? Do I think they'd even care that I make this effort for them? If not, then why am I bothering? So that's why I report in C firstly now. And I should add, normally I still do the math and report both numbers, just that this morning I decided I was going to make a stand. It had nothing to do with the fact that I had only one cup of coffee by that point (hey wait I still haven't had my second cup ... what the ... I must be totally losing my grip here .. where DOES the time go), and didn't feel like doing the math. .... no, ok, wait, that's really the whole reason, I admit it ....

Mine had the switch and I set it to F. after over 25 years of keeping fish I know what 78 degrees F is and so on, but I coulden't look at a C reading guage and tell you instantly if it is ok or not. Also like was pointed out already F is more percice using only whole numbers.

Steve

Steve, F doesn't just use whole numbers.

Tony, we'll expect all future numbers to adhere to Canadian metric units. We may not know what you're talking about, but we support your stand. We won't do it, but you should!! :razz:
BTW, it's about 84.2 outside here today!!

:lol:

Well I'm happy to report that after running a small Honeywell Forced Air type fan(cost $25) from Home Depot, it has helped out my reef BIGTIME :exclaim:

It's now 2pm and peak temperature is 94 outside in the shade using a good old mercury thermometer :eek: :mrgreen:

Today I removed the lid on my 4gl sump, setup the fan, and have had it on all day, cooling the water surface of the sump. I am happy to report that after yesterday's high of 86 I am now sitting at a stable 81. That's a whole lot better in my books. As for evaporation, I just brought my sump back up to it's normal level using 1 litre(or a 1000ml :mrgreen: ) of bottled springwater. So I guess that giving my tank a bottle a day is not too bad :biggrin:

Goodluck with the heat everyone!
cheers, Rich
