DO I have enough flow?

[mark]

More than just gph but also layout but for comparison on my 145g have a Dart on a OM-4Way (3600gph less CL loss which don't expect much) and ~1000gph return from the sump. Lot's of SPS growth and sheltered areas so as good on the LPS. Had a crash but really don't think due flow, my signature gives an idea of tank load.

what's your flow thread

I have a 150, closed loop with Dart (3600gph)on a OM 4way and return from sump at about 1500 gph going through a wavysea, and a wavebox (unknown amount of flow). Sps are growing like crazy for the most part and the only coral I've lost so far are due to me going away and not being able to rescue a frag that has fallen into a hammer coral and another frag due to another sps growing into it and touching it and stinging it. So I'd say my flow is sufficient (for now.....we'll see when the corals grow huge).

I'm also part of the dart + OM 4-Way club as my return system and then I have a mag 12 pushing water through a spray bar in behind my rock. In total it should be about 29x/hr or 3500gph in a 120gal. Most of the water flow is focused to the center of my tank where I keep my acropora. Surrounding them is a combination of clams, LPS and less flow demanding SPS like montipora.

So I should be good for a while then. Just need to figure out better SPS placement and whatever else I'm doing wrong LOL

Dan, you could try adding a few of the cheaper powerheads hidden off in the corners. I have 2 Korillia 4's in my 120g and I need to be careful where I point them or they will blow the sand around. They are only about $50 each so a fair bit cheaper than a mp40
