Hiatt filtration system

[CaptainGreg]

I had some red slime bacteria on my rocks afew days ago and it is now turning white. It seem to be dying.....

[CaptainGreg]

My ALK is a little bit low, but my cal is high. It might be the reason I point the return line too low into the tank and accumulate too much carbon, but I have top water movement on the top and in the sump. I will try to point the return water to the top of the tank if ALK does not return to normal in a few days.

I can't find any pic on your profile. Out of your tank or tube flow needs to be at 2500gph coming out. Do you have a gate vavle?

One of our Board Members (bstreep) was running more than 10X on his tank (I believe). His tank actually became too sterile using the Hiatt. He has a few posts on RC on some older threads on RC regarding his Hiatt experience.

From what Snake has explained, the bacteria settle everywhere in the tank, not just in the carbon tube. They will not be ejected out of the tube with flows in excess of 10X.

The whole point to the required flow rate, is that it helps increase over all oxygen content of the water to assist with the metabolic rate and reproduction of the bacteria (this is per Mr. Hiatt not me).

That could be one reason Bill had longterm problems with his filter system.

When I first start this system I use about 130gal of tap water to make saltwater.

did you check out my profile. I have pictures of the carbon tube design. I have two Baracuda pumps in series and it should kick out at least 8000 gal/h.... on a 250 gal tank with 50 gal of water in the sump. I measure the max output of 6000 gal/h the system with one large carbon tube and three large caclite tubes. The over flow is barely keeping up with it. I have problem with the water staying cloudy for two days now. It seem to be kicking out lot of dust from the calcite or maybe the RN.

If it does not clear up soon, I have to turn off my second pump.

I check your profile at rc nice pic. Boomer is something else at rc.

I think the problem with too much flow is that you need some exposure time to within your carbon system. The single most critical part of the process is oxygenation.

In my case, it worked too well. Even with 1 torpedo on my 215, it worked too well. For a FO tank, I wouldn't hesitate.

Everything looks great Cory! I wish I could get my corals to grow away from the rocks! They cower to the LIGHT!

I'm trying to talk my wife into letting me get a Canon T1i so I can shoot HD video and get better quality pics. She likes to take pics of all our kid and nature settings. So I'm playing that angle right now. Wish me luck!

Anybody use sea lab 28 with hiatt systems?
