I picked up my package and the reactor is a lot bigger than I was expecting. The reactor instructions say to use a minimum depth 2" which is going to be close to 100ml.
So I have a couple of questions. Can I get away with less than the minimum 2" depth? Would that be a hard rule or can I try less and see if I can get the correct flow? The reactor has sponges that are rather coarse. Do I put the the gfo directly on the sponge or add a layer of filter floss? The instructions for the rowaphos say it can be sandwitched between layers of filter floss but I don't think that was for use in a reactor.

You can get away with less than 2" depth, all you have to do is turn the nozzle to control the amount of inflow from the pump to the reactor. Make sure that the GFO has a slight tumble, with 30 grams of GFO you won't need alot of pressure for it to tumble, that why the output of the water volume is very low and that's why it would take some times for all your water to cycle through the reactor. Eventually you want to increase the media to remove the phosphate in your water and starve out your algae. If your phosphate is high I would replace it often. If your system is low nutrients the GFO can last over 6 weeks but I replace mine every month, I've never seen it last longer than 6 weeks.
