RW 8 for a standard 90

[intyme]

Is it to much? Or should I get a 4?

I have two rw8's on my 72 and they work great. A 4 may work but I would rather run an 8 at 50% than a 4 at 100%.

I have two rw8's in my 90g. lps/softie tank and run them on the lowest setting in W1. I cant use else mode because they are to powerful. If your doing a sps tank i'd definitely go with the rw-8.

Prob not sps, maybe a few chalices, mostly Lps, zoas, shrooms.

I have 2 rw-4's in my 29gal at 100%, no way would I try running the same setup on a 90. Get 8's, or maybe even higher.

I have 2 RW-8 on my 4ft 90 gallon with one on each end of the tank. Works well with my rockscape.

[intyme]

I've also been steered towards one 8 and one 4 on opposite ends

Two 8s will be enough with the coral you are planning to keep.
