How often do you do water changes?
 

Just wonderin. Its been a slow day :razz:

Tell me about it!

I siphon crud off the bottom of my tank twice a week. Each time I do that, I do about a 2-gallon water change...and that's pretty much it! :wink:

Oh yeah, that's on a 55G tank.

every 2 weeks, 12g on a 145g total tank volume.

Bwahaha, you guys didn't even let me get the poll up. Maybe the board isn't as slow as I think :razz:

I do 15g a week on about 100g total water volume. Its getting old.

Ha ha ha. I was just wondering, "huh, where's the poll?"

*chompin' at the bit*

LOL i think ppl are on but just dont post anything new. We are waiting for you to post new stuff for us Christy:lol:

i'm just bored :biggrin:

Me too. Hey, we need to get some sort of forum chatroom going. Hours of entertainment for those with tedious desk jobs!

I like too do 6gallon weekly,out of 40g total water volume.

I do a 3-4g change weekly on a 20g Tank.

You're totally right, heck its only been 30 mins since I posted this and already 8 replies :biggrin:

I'll find more stuff to post then :razz:

On a 28 gallon aquarium, we change out about 20% of the water weekly.

I try to do 25% once per month. Sometimes I let things slide. I'll have to check when I last did it (I write it down on a whiteboard in my basement) but I have a bad feeling it might have been February because I don't remember doing it in March. I guess there isn't much left in April, I better get on with it, thanks for nagging .. er .. reminding me :p

I change about 8% of my tank volume every week. It's all part of "tank bonding", can't wait to do my next water change, we've become so close my tank and me.

I was doing bi weekly water changes but everything has been doing so awesomely well I haven't dared do anything for awhile so I checked off the "strange schedule that makes sense to me" option :lol:

I do 15g a week on my 85 gallon total system and 15 gallon week on my 116 gallon total system at work.

I checked off the strange schedule. I try to change about 20-25g once a week on my 110g cube (probably 150g total volume). I usually do my 2 nano's at the same time with about a 50% water change. On my 230g and 190g I am probably more at the 2-3 week interval.

I do 5% weekly on a 60 Gal tank, almost no sand left cleaning up the crud.

I change 40G every month on a 180G tank. I try to do it every two weeks but it usually ends up being a month.

Everybody's schedule makes me feel bad about mine. I havent done a water change(just top offs) for 5 months now. But I will be doing one this week since I need the established tank water for a new nano :)

After reading all the posts I wish I had a nano tank. I do 55 gal water change weekly on a 300 gal tank. Is it a bad thing my kids college fund went into salt mix?

DUDE! That's a little nuts...well, for me, considering my aquarium IS 55 gallons, lol.

My parents spent my college fund on a time share. :mrgreen:

I do a 40 gallon change once a month on 200 gallon system.

I'm about the same as Joe, 50g change once a month on my 220.

I do a 25 gallon water change every-other week on a 125 gallon system. I used to do weekly 3 gallon water changes on my 33 gallon. I miss those days. :sad: But the bigger tank is way better!:biggrin:

I do 20 gal biweekly which is about 10% of my total water capicity, (more like 15 - 20% if all the rock is put in the equation). I used to do 20 gal weekly on 160 gal but I started to think that was a waste of my time and switched to biweekly after I plumbed in my refugium. The system certainly hasn't suffered from it.

Hey!
where's the not as often as i should option! ;)

10gal every 2 to 4 wks on a 77 with a 30 gal sump/fuge

10gal every 2 to 4 wks on a 77 with a 30 gal sump/fuge. A good sized fuge with lots of macro algae has taken me from having to do weekly water changes to not even 'having' to do them when I do. Couldn't imagine ever having a tank without a fuge now that I have one.

Water changes help replenish trace elements so even if the water seems to be ok it's still a good idea to do them on occasion:smile:

I do a 1 gallon water change once a week on my 5 gallon tank

340 gallon system. 45 Gallon Automated Change weekly.

10% water change and gravel clean every week.

would 30% water change weekly be way to much?? your opinions welcome.

my opinion is that it all depends on bioload... my tank have a very high bioload so i am opted to do this, and i think it might be the cheapest way to maintain a heavily stock reeftank in the long run. considering we are enjoying some nice prices on salt mixes in calgary.

Almost never.

In 3-1/2 years I have changed maybe my tank volume (120 gallons) once in total.

I keep meaning to set up a system with a garbage can and pump to do monthly 20 gallon water changes but I never get around to it.

Mostly everything is doing OK though with nitrates varying from zero to barely measurable.

I like doing the one big water change every 3 months compared to the small water changes every 2 weeks or monthly. Last water change was late September, then I just did a huge one this weekend. Originally planned on doing 90g on a 210g reef, by draining water from the fowlr, siphoning reefwater into the fowlr & then topping up the reef with new water. Unfortunately, I miscalculated & ended up draining too much out of the fowlr which caused me to have a near empty sump so I had to make up another 40 gallons for the reef. So, in total, just did a 130g water change on the 210g reef with 75g sump (total water volume minus LR & LS etc. is probably 180-190g).

On the other hand, I run a RS250 skimmer, Phosban reactor, semi-remote deep sand bed, micron sock, and grow lots of macroalgae in the refugium/sump so the water quality was still surprisingly good despite a long time between water changes and a high bioload/feeding regimen. The corals look the same (very good) before & after the water change, whereas in the past, usually they look a lot happier after a water change. Hmmmmm.

I'm not recommending this water change schedule for everybody, just posting up what works for me.

ZEOvit users are instructed to do a 6% water change every week. My system consists of 425G + sump and I do 30G every 3 to 4 weeks.

I want an automated water change system. :lol: Take the lazy mans way out. :mrgreen:

Go
 

I took the lazy way out and plumbed 3 tanks into a common sump so I could use a single ATO. Makes water changes a lot easier. I siphon crap out of the bottom of the tanks, then move my top-off pump from the ATO pail to my water change pail.

When I turn the ATO back on it refills my tanks and stops when done. I just need to remember to move the pump back into the top-up pail of fresh water when done.
