Is 30x turnover to much for LPS

[jaydub74]

I have a 86 gallon tank that I have yet to setup - I'm planning for the following

two Korelia (1200 gph each)
return pump (500 gph)
= 2900 GPH total or 33 x tank volume turnover.

What has been your experience?

thanks

It should be fine because the flow pattern of the korallias is very wide so it should give the corals a nice sway

I have 2400 in my 90 and I've not had any trouble. the corals all move alittle but none are getting bombarded. I'd say 2900 in a 86 would work great if done correctly.

I've got an unmodded tunze 6025 (660gph) and a sure flow kit on a maxijet 900 (1000+gph) giving me 1660+gph flow on my 42 hex or a tank circulation of about 39.5 per hour (this doesn't include the return). The euphyllias aren't as expanded as they are in a more moderate flow, but they look nice none-the-less. I just need to be careful of the blastos as they don't like high flow at all IME. FWIW I'd like to add another modded maxijet or tunze somewhere to increase the flow and keep particulate in suspension.

Good luck.

I have 3600 gph (gyre style flow) on a 67 gallon tank. LPS do just fine in my tank.

There is really a lot more to this question than just giving the overall turnover rate.

Some of the lps are bottom dwellers (like to be on sand) like Trachyphyllia, Scolymia, fungia, etc. They do not like direct flow but enough to keep them free of debris. Other LPS are found in a vertical orientation on a reef wall, etc.

If you put a Euphylia in front of a pump for circulation, they will not expand well and can suffer. It has a lot to do with actual placement in the tank, are they in the direct "line of fire" so to speak and are they placed properly according to their natural location in the wild.

The total "turnover" of a tank is actually a very useless number when trying to determine whether a coral will do well or not. Much better to ask where is a coral found in the wild (reef flat, reef wall. lagoon) and then doing your best to replicate that.

E. Borneman's book on Corals is excellent for providing this information.

SPOT ON!!!

I have a koralia #2 in my 33 gallon, my euphyillas are farthest from it, not expanding fully but not unhappy either, my pagoda cup is right below it and loving every minute. The brains don't seem to really notice but my plate moves away from the flow. Like lhoy said it really depends on what lps and where they are, I think you could pull it off no problem, just put the wavy expanding stuff below or farther away. I have several softies that really enjoy the flow that I use to break it up a little in my tank.

Just be cautious where they are pointed & you'll be fine =)
