thanks for your help
do you think i need another type of filtration, like a canister filter or would the 300bio balls with the 1200gph would be enough.
before the water hits the bio balls they have to go thru 5 layers of filter media that i had install
what are your thoughs on this?

Personally, I like overkill. Why not add a canister?

I was thinking the same thing.
 
I posted earlier but seems I offended the mods when I said there is no reason for overkill filtration.

Stop deleting my posts!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I answered the guys question about "why not add a canister".

Since it sounds like you're new to sumps, I would also caution you on the horrors of backsiphoning. If your pump output is low in the tank and the power goes out, the water will back siphon into your sump until the water level in your main tank has breached the output nozzle. What this means is you will have a flood because your sump is probably not large enough to hold a large percentage of the water in your main tank. Solutions to this problem include keeping your output nozzle at the surface and/or drilling a hole in out output just below the water line so that if there is a backsiphon the siphon will be broken once the water drops below the hole you drilled. You didn't mention mention the configuration of your overflow, but make sure that it is high enough in your tank so that if you turn your pumps off there won't be so much water overflowing into your sump that it overflows the sump.

Has anyone tried PVC check valves to deal with the back siphoning issue? I am planning on setting up a sump for my new tank (if I ever manage to pick it up) and would like to put the return near the bottom to increase the circulation. I'm not sure I get how pulling water off the top with an overflow, and returning it to the top circulates water through the entire tank. That is unless you point the spout down, which increases the pressure needed from the pump?

I use them exclusivly...I plumb one size larger to be sure no restriction in flow...
There are others that swear they will plug in time and don't...I have never had problems with mine...
 
Why would they plug? You are pushing filtered water through them. I have had copper check valves on my furnace for 15 years without problems.

Hot water in a closed system is way different than an open system with algae buildup etc...they don't really clog but they could foul if you don't keep them clean ...
