Flow?

I am thinking of getting the MP10 that you suggested.

Do you think one MP10 would be enough for an SPS 55g tank or do you think I should get t two?

 

The more the better, but keep in mind the price of them, so if you can only afford one right now, get the wireless one so that later on down the road when you get another one, they can talk to each other .

If price is an issue for you, which it is for 75% of us, then koriia is a real attractive option. You can get three korila 750's for $100 off amazon. That'll give you 40x turnover rate, which is awesome, and you can point them to have high/medium/low flow areas. And the 750's ane "small" so that's a plus too. Just something to keep in mind

 

+1 I have (2) 750's and (1) 1050 in my 55. Total with sump return of about 50x turnover
