OH i guess that an opinion is no good here. So i take that only 2-3 people here know what they are talkin about. I have been all over reef across the world , I was merely stating I didnt feel a huge current in the reefs might be a hugh flow flow,\

To quote your initial post "I can never understand the flow that people are putting thur their tanks, I have been in the ocean near SPS and have never felt the flow that some people are throwing at them either. ITs funny as heck... "

I think your inital post had a little sarcasm, now you got a little back I guess, don't read too much into okay? Your opinion is as valid as anyone else's.

No i was stating that it's funny How it that to have a smart ass affect on the post. I was asking about the post that you put in there, I was waiting for you to chime in Steve Adaboy. To me that sounded like sarcasm to me, that is why i posted..


mike

any way i'm not trying to start waves here, I was making a post if it came out sarcasm ,my apoliogizes if it sounded like a smart ass.

Likewise, my point wasn't to offend you. So let's just put those comments behind us.

[Skimmerking]

Already done ,

thanks

P.S I wish tha all the posts can be sorted out like these ones ..

i'm thinking of getting a tunze sometime or another for some nice flow

yup, I am using them in addition to my Tunze I like them so far.

Mike, how did you change your name and keep your post count never realized it was you until I read your Sig hehe. anyways I was not trying to discount what you said as I have been snorkeling on a few reefs myself but I think you were talking about power head blast, was I wrong? take my tank I am up to a 90X turnover rate in the tank. no matter where you put your hand you feel a gentle current not a hard flow anywhere well unless you put you hand right in front of the tunze. So it is possible to have high flow with out the blast.

One reason I also like the higher flows is I find the corals actually grow faster and more robust. I have also noticed a correlation to bleaching and flow, I am finding that the higher flow I have through the tank the less chance there is of a coral bleaching when I add it to the tank. I believer flow is often overlooked or the wrong type of flow is added. be for when I had my maxi jets I had to place them in such a manor that they wouldn't be pointing at anything as they would rip the flesh off my corals. at that time I had a flow rate of about 10 to 15X. with the new set up it is the first time I have not had to worry about where I put corals as although I have increased the flow rate by leaps and bounds it has been dispersed through out the tank and the type of flow generator (power heads) are that which make a wide flow not a blast. this constant high flow in my opinion makes it easier for corals to get rid of nasties that they need to get rid of and also makes a higher concentration of bacteria/nutrients/ect that they need available to them by the fact that more new water/min is made available to the coral and the flow is such that it keeps particulate matter suspended for them.

The spelling didn't give it away...?

Try RC for a 'Borneman Flush Device'. It's basically a toilet flapper with a float attached. Simple, simple, simple. I took a 10 gal aquarium and threw it on top of my canopy. I siliconed in a baffle near one side so that part was always full (my mini-sump - too bad the new heater I got doesn't fit properly :/) and drilled the bottom of the larger area. The toilet flapper is a standard PVC fitting and screwed onto the bulkhead fitting on the hole. Due to the minimum height of the toilet flapper part, the water level can't empty below about 4" of water. Hey! Instant fuge! So the water level rises to the very top of the tank before the float on the flapper rises enough to open the flap, and it surges down to 4" again.
Here's a very old photo a few days after it started working. No new photos are possible so long as my camera decides it requires an entire set of batteries to take 3 photos.

Rikko, tell us a bit about how you have the outlet of the surge enter your tank. Does the pipe sit submerged, or above the surface, or midway, etc. Also how many bubbles do you get from it?

I briefly toyed with Borneman surges myself a couple years back but I didn't quite get the effect I was hoping for. I'd love to get more height on the reservoir and try again, but more height means more air in the discharge tube so I see a bit of a catch-22.

PS. Get a buddy to come over and snap some pictures!

[Rikko]

Well, as far as physical connections, I've got the flapper welded onto the bulkhead via a single coupler - let's say there are maybe 3" of space in there with perhaps a 1.5" inside diameter. Then it runs down about 6", hits an elbow, travels another 12" to the corner (I should have planned the bloody thing to account for the lighting! Now I have to bypass around it!), and down the final 6" or so. The outlet itself is a 90 degree elbow so it's parallel to the water surface but submerged at all times. Another guy on RC I was talking to was having huge problems with the flapper closing but it ended up being caused by his outlet being above the surface.

Here's a shot from a little farther back about a week into the cycle...


Bubbles? There are a lot, but I've stopped caring about them so much now that I found a good position for the powerhead to deflect them off the corals. Once the surge has begun no new air siphons in, so it becomes a "clean" surge after that.
If bubbles are your enemy, there are 2 options.. Solenoid (the clicky would annoy me more in the night than the gush of bubbly water, somehow), or a vacuum design. I'm subscribed to an RC thread somewhere where a guy actually built a chamber within his surge chamber to control the air and the end result is no bubbles! I've read it a couple times and never been in a temper to fully understand it, but I'll dig up the link after/at work today.

One thing with the Borneman, however, is that you NEED to guarantee a minimum rise of water level in the surge tank. If it's too slow you *will* end up with a flapper slightly starting to open, then water draining and the whole contraption closing down again.. Water level rises a bit again.. Flapper lifts slightly.. Yeah.
