Hello,
I am working on getting all the plumbing together for my 270G DT and approximately 70G Sump. The sump is not underneath the tank, but located behind the wall that the tank is on. I was planning on using 2 cor-20 pumps for my returns. One was going to run a fluidized canister and the other I was planning to run my 50w UV Sterilizer on. The Sterilizer recommends about 1500GPH for algae control. I am estimating that the vertical head pressure will be about 4.3ft. There will be about 2ft of horizontal pipe and probably about 4-5 90" elbows.
I am starting to think I will not be able to push enough GPH through the UV filter to make it effective using the cor-20. Can anyone doublecheck my math or help me out with this?
I have a 1" return that I will be coupling to the 1.25" COR-20 output
I am thinking I have two options to remedy this.
1. I can get another, more powerful pump for my return and continue using the design I mentioned above. The only thing I can see that will be strong enough, I believe is the Abyzz.
2. I can get another return pump and dedicated it to the UV Filter. Currently the tank has 3 1.5" holes I was planning on using for the drain and 2 1" holes for the returns. I was planning on doing a bean animal style drain. I could use one of the drain holes and reuse it as a 3rd return for the UV sterilizer. I think this may be overkill, but I am not sure what other options I have.
I heard it is best to take water out of the sump and return it to the DT for UV, is there a huge downside to having the water get picked up from the refugium area in the sump, go through the UV and then drain into the return area. My sump is setup as follows:
DRAIN---->Skimmer--->Return--->Refugium
One of the return pumps T's of into the refugium and then the refugium overflows back into the return. This is a Geo AFR sump.
Thank you for any and all help on this.
