Awesome Reactor By Ericm on 11/29/2010Ericm would recommend this product to a friendI was looking for a reactor for my new frag setup and i bought this after doing alot of homework. Geo's were out of my price range and this one was a great price so i bought it. i was very surprised how well built this was. i thought it would be cheap thin acrylic for the cylinder and a crappy pump. boy was i wrong. i hooked it up and controlled it via my RKE and loaded up with media and after a month i seen dramatic difference to my frags. the growth and color was very noticeable. no more over dosing 2 part for me anymore. best investment i bought.
