Thoughts on Nero 5 at 100% to flush away detritus in 3-foot LPS tank

ItalCanadaReefer · Jan 28, 2021

I am thinking of blasting my AI Nero 5 at 100% (3040 gph) twice a day for 5 minutes a time to flush away detritus. Do you think this will be far too harsh on LPS corals? I am noticing lots of uneaten food shooting right up when I do this, but I am wondering if this would be detrimental to LPS once I add them in.

Only one way to find out! I think 5 minutes is overkill though

Crank them up at night when things are closed up, I like to add a very high flow at night just for your reason

Huh, my pumps actually have an automatic feature that cranks them down at night so the fish can rest easy

I run nutrient transport mode for an hour cycle on all 6 vortechs, fish seem fine and they all sleep in rocks. I would like even more flow but due to having a mixed reef its a no go. I can see it being an issue in a small tank.

I have the icecaps but 3 times a day I turn the pumps off for 5 minutes followed by 100% for 5 minutes. The rest of the day is pretty random and at night turned to about 40%. Everything seems to be doing well with this and it's a copy of one of the settings on the hydros wave engine, "hurricane mode."

I have two Nero 5’s in a 4 foot tank. I put them both on 100% once and things got pretty wild.

Yeah I like that it flushes detritus from dead spots and from the sand bed but I’m worried it’s too much for soft corals. I saw clove polyps seemed to close up when on at 100%. But then again, I’ve only had corals in there for two days. I’m just not sure if it’s overboard, and pushing it to the point that it’ll kill these less follow-tolerant species.
