flow in my 180??

[colgan10]

I have had a 180 and it's been set up for about two months now. I have a mp20, and three maxi-jet 1200 with the mod, is that too much flow? I had just one maxi-jet with the mod and mp20 in the tank and added the other two tonight and my fine sand bed is everywhere i'm thinking that is going to be to much flow for the fine sand. My tank is a sps dominated tank that i just moved into from a 75g. Any advice would be helpful. I feel like this shouldn't be too much flow since i see many people on here with tons of flow as well.

is always good to have a lot of flow in a SPS tank

try to upgrade your MP20 for a MP40


make sure that the sand is a reef grade sand other ways your will be move all over the tank

I think the general rule for sps tanks is 40x-50x total turnover.

sorry the it is a mp40, and it is bahamas very fine sand reef grade but it is getting blown around everywhere is that normal for a new sand bed?

FWIW, in my 180, I have about 7200GPH total circulation.

1200 from the sump
3600 from closed loop
2400 from a pair of Koralia 4's

SPS tanks seem to do best between 30-50x turnover rates.

yea i totally understand the need for flow in a 180, i currently have 9600g total turnover, i'm concerned with the sand bed being blown around everywhere. I just want to know if that is common for a new sand bed and if i should not run that much flow till the sand matures or is it something you just run all the pumps and let the sand do what its gonna do?

I have 2 MP40's in my 120 cranked up all the way in reef crest mode. I would think 3 MP40's (or similar) would be about right for that size tank.
