WP40
 

I have a 90 gallon tank with half SPS and half LPS, thinking of giving the Jaebo WP40 a try, would 1 be enough flow?

I have a 120g with mainly sps. I run 3 tunze 6055 and 1 wp40. I think 2 would probably be enough, but you would have tons of dead spots with just 1.

As soon as mine arrive in the mail i will let you know..:lol:
But i have seen a 120G(4 feet) with 1-wp40, and 3 Koralias to prevent dead spots..

Depends on the dimensions of the tank. If its a standard 90 I would put in 2. I have 2 in my 100 gallon but it's also 26" wide.

2 wp40 for the 90g or 1 wp40 1 wp60. Jebao ftw!!

2 wp 40s will be good.....FTW lmao

i have 2 wp40 on my 5 foot by 3 foot by 12" high frag tank and they work wonders, use two you could use one with a voltage reg to turn the power down if there to much flow 12 bucks for voltage reg
