Water flow

[sinkingbeach]

Do you think 2 SEIO Super Flow Pumps (Model M620) would be enough flow for a 75 gallon fowlr or is it overkill? I may go reef at some point, but right now I just want to set it up as a fowlr but purchase products that will work for a reef also.

I personally do not believe you can have too much flow - (unless there is a constant sandstorm). Go for it.

One of the reasons that SPS'rs go BB is to prevent a sandstorm. I agree with philS19, too much flow is like too much money, there is never enough. Now the right flow is something else!

I would get the 820 over the 620. I bought an 820 and wish I would have got the larger 1100 or 1500. For a 820 it does not seem to push the water very far, maybe 3 feet but it is a nice gentle flow.

I would also go for the 820 or larger. They don't force water as MaxiJet do. You will hardly notice the flow if you go lower.

The 620's are too small for you. I have one and an MJ1200 in my 30 gal cube and I should have gotten the 820.

I agree with everyone above... The more flow the better.... Think about how much flow is generated in the ocean.

instead of starting a new thread,

I have one pump running from my sump to my tank so I'm guessing a need a power head? I have a 110g tank. From what I understand a powerhead just sucks in water and spits it right back out to create a flow? No need for hoses running all over the place?

your right about the discription of a power head, it just moves water, depending on your live stock you may wnat more the one.

I only have LR and fish right now but I do want to add some corals in the future when my tank is suitable enough. does my main return? pump do enough or do I need to add another powerhead? and where should I add it? opposite side of the tank?

[swoopx]

only a few fish at that

So, if you can't have too much flow, then where do you put "low flow" corals. Aren't things like torch corals, clams, and Xenia happier in low flow areas?

Usually if your going high flow, youre keeping sps and most sps'rs don't mix sps with lps and softies. My Xenia prefers a low flow, and only pulses in the low flow.

You can place your "low flow" coral like LPS on the bottom usually right under the powerhead is a good place as there is minimal flow there. You can have LPS in a high flow system you just have to work on placement and may have to move some rocks around to control flow.
