venzi Posted August 7, 2022 Share Posted August 7, 2022 Hi. So a common setup for UGFs and powerheads is to place the powerhead at the top of the uplift tube. This is obviously a quick and convenient setup. However, in my 20H tank, noise and aesthetics are a concern for me. Having the powerhead at the top of the uplift tube is not ideal for aesthetics nor noise. Also, it seems the slowest/smallest powerhead I could find are like 100gph and higher. But there are smaller pumps (https://www.amazon.com/dp/B086G9M568/ref=emc_b_5_t?th=1) that can do like 50gph which would theoretically be quieter. So I was curious if anyone has tried to place the powerhead at the bottom instead (to conceal the powerhead more (perhaps even completely within the gravel) and maybe have some tubing or pipe stick out to the top. And maybe have like a 90 or 45 degree bend at the top of the tubing to agitate the water even better than having the water go straight up. As shown in the attached picture, I'm not sure the best way to setup the intake for the pumps. For Pump A, would it be ok to just place the intake flat on the UGF plate? For Pump B, would I drill a hole into the UGF plate for the intake nozzle or add some tubing/pipe that would somehow affix to the where the uplift tubes typically go (not sure how to affix it - maybe silicone caulking?). I guess in either situation, I'm trying to understand how much of a "seal" there needs to be be in the intake to ensure good enough flow is coming from below the UGF plate and not the surrounding gravel.
