I paid 8.99 a pound for the stuff I got from kees. For GFO if they had it I would have been paying twenty two something a pound. Its been a day or two havent noticed any results yet except where the algae I had before was a darker green it now seems to be turning a brighter green hopefully this means its dying off.

As for the tumbling there is some tumbling in a couple areas.

Chemically I will pry do a test this weekend and see.

Oh as for the pump its the one the recomended to me the cobalt mj1200.

The assembly was so easy for this dual reactor from BRS. I realy hope it does a great job for my tank.
