I have an Aqueon 210 with dual over flows and dual returns. Planning on going away from filter socks to a Reefmat1200 and eventually a UV sterilizer. Looks like I have a few options
For the overflows I think I have two options.
1. Run them both to a wye and then to one side of the reef mat (don’t have room to run it to both sides)
2. Run one return to the reefmat and one to the UV sterilizer.
For the return.
A. 1 return pump to the sterilizer then a wye to both returns.
B. 2 return pumps, one for the uv sterlizer, 1 as the main.
2B is Plan A at this point, wanted to get some thought on this.
My main concern with option B is cutting flow through mechanical filtration down by 50%. However, Currently the drains are loud, I have never been able to solve this, have 1.5” hose for the drains and there is a lot of air in it. So I am also thinking maybe more water with less air through the now 1 line directly to the reefmat will be quieter. I would expect the closed loop UV sterlizer here to be pretty quiet as well.
