Control PO4
Dear all bros,
My tank PO4 level is getting too high. As my tank use only external pump and no sump tank. I check with some shop, they suggest me to buy a PO4 reactor. Price for reactor is SGD95/-, Reacting agent is SGD65/-. (Too expensive for me) Can any bro teach me where I can get a cheaper reactor? |
