I am using an Dennerle Cycloturbo internal reactor on a 125g tank and I am extremely pleased with him.
Previously I try to use an Dupla 400 and an Tornado - external reactor from Aquatic nature. Both reactors fail to satisfied my PH needs. Dupla wasn't big enough and the other one proves to be lost money.
