phos reactor question

I have some of the dreaded bryosis algae in my new 55 gallon been up for 2 months. i have been scrubbing it to get rid of it and hoping the problem will correct itself. I use R/o. and have gotten a sea hare and chaeto in a fuge and cuc with lawnmower blenny.

I think i need to add a phosban reactor and was looking at the 2 little fishes one? any others i should be looking at? what pump do I need to drive it?

thanks

 

you could also look at the next reef reactor its a nice quality reactor you could run them with a maxi jet i run mine on the mini jet 404 and 606
