Mp40 settings

KOJ · 03/02/2016, 06:07 PM

I need some advise. I know the mp40 questions have been asked a lot, but I can't seem to find an answer.

I have a 90 gallon tank and I am currently running two mp40's. I have a frogspawn, bubble coral, open brain, and a rbta. I have to keep my mp40s at 20% just so my bubble doesn't rip apart. I see a lot of people say they run them anywhere between 50 to 100% with similar setup.

My question is how do they do it? I would really like to crank them up to get more water flow. Currently I have the bubble under some rock work so it will block some of the flow.

If I'm missing any information you might need, just let me know. I've moved it around several time looking for the right spot but now I think I'm just aggravating the coral.

By the way, my lighting is two onyx rapid LEDs with 80 par.

Thanks

Placement, rockwork, quiet zones.

I run about 70% on a 90g in a mixed reef scenario. The torches get a LOT of flow without any issues.

The Pearl bubbles can take more flow then the larger grape size polyps. You just may have to adjust the rockscape and provide a low flow area somewhere. The area just below the pump may be suitable too.

Thanks for the advice. Currently I have it under some rock work and it seems to be doing better. I really think that I need to add more rock work to interrupt the flow more. The bubble is "grape size". My fear is having it under the rock, it will not get enough light.
