    Does the "bow" in bowfront tanks aid in flow when your return line is aimed toward the front glass as opposed to the traditional flat front tanks? It seems to me that it helps quite a bit. Just wondering if others feel the same way?

    I guess its possible if you hit it straight on. otherwise I think the bow is just there to piss me off when I scrape algae.

    I think the bow is just there to disrupt my view LOL.
    I point a powerhead from the back to the front of my flat front tanks and it works well, I don't see why it wouldn't work with a bowfront.

    I seem to get very good flow from just my return which is done with 3/4" loc-line and a 3" flare on the end of it. I also have a Korlia nano on the overflow side pointed across to the tank to the return side. When I have my 2nd PH (Koralia Evo 750) on, most my corals seem to not like the heavier flow. All corals are LPS and softies no SPS. It seems to me most people have 3 or even 4 PH's and with my 2, it seems like too much flow. What gives?

    it does depend on the corals, but also the powerhead aren't there exclusively for the corals they prevent dead spots.

    And dead spots are areas that don't get enough or any flow which allows detrius, waste,and uneaten food to collect and pollute the water correct? So if all my residents are happy and healthy, and I have no dead spots, I should be ok on flow?

    yes but to check I would pick up your powerhead and point it at areas of rock to see if detritus comes off.

    Gothca, I do use a turkey baster and blast the rockwork when I do a water change every 2 weeks and I get a little bit of dust and sand, but doesn't seem to be much. No deadspots on the sand near the rocks, no nuisense algaes.

    It'll also depend on the size of the tank, the power of the powerheads, and how much rock is blocking how much flow...which means everyone's tank will be different! I only had a 38 gallon tank before, so I just had the mini powerheads. With the 55 I just got it came with a larger ph that came with it (dunno how much it moves per day), and stuck 2 of my minis in there. Just bought another large ph today cuz the minis just aren't cutting it in there. I'm hoping to just get away with the water return and the 2 higher flow ph's, but we'll see!
