Do I really need two of these???

[whosurcaddie]

Ive recieved two of the wireless vortech pumps for christmas and I have a 120 gallon tank that is progressing into a sps tank. my question is wouldnt one of these pumps be enough flow for my size tank. Or for sps should i keep both of them.

if you told us what else you currently use for pumps we may be better able to help you because right now we don't know if you have a closed loop, other pumps, etc...
