Mad Reefer

Hi, I am building a tank with high flow that will result in even higher flow through the sump. I'd like to slow the flow through the refugium chamber of the sump. I have seen this accomplished by placing the return in a center chamber then split the return flow between the display tank and the refugium. I have also seen this accomplished by splitting the return and running a lower flow through the refugium Neither one of these works well for my application. I wonder if anyone has seen it done another way and can direct me to any information on it? One way I am considering is to provide a bulkhead on both entrance and exit of the refugium chamber with ball valve/PVC allowing control of the amount of water allowed to bypass the refugium thus slowing the flow through the refugium. Something like this image below if you can imagine adding PVC with a ball valve at the bottom of the refugium connecting the entrance to and exit from the refugium (shown in the below digram from left to right). When the valve is off it would be at maximum flow through the refugium. The more the valve is opened, the lower the flow that actually enters the refugium. I might just build it to see if it works as expected. But I'd rather see if its been done before and how it worked out. Anyone seen this out there? If you dont like the idea of running PVC through the refugium area , you could always run it out one side of the tank before the refugium and then back in by the return.... Thanks for reading! -Madness

Hi y'all I need a new canopy for reef tank. Its disintegrating. Standard 1.5 foot by 4 foot canopy needed. Typically found on 75gallon and 90 gallon tanks (the difference is tank height so it doesn't affect canopy size. Please let me know what you have. Thanks!

My ballast died and my new one is pissing my tank off. Anyone have one of these old ballasts lying around? looks like this

Well, I never lost one in my powerhead. you can see it them in the full tank pic in the first post of this thread. korillas i think
