i sold away the denitrator already due to lack of space to accomodate it. Gonna build a refugim tank instead with DSB.
I ahve not use the Pure Nitralock before, so can't really comment on the product. There are many ways to bring nitrate level down. For a start, dun feed ur fishes too much. Secondly, dun add any new fishes at the moment.
Can consider investing in a denitrator. Reefdepot does carry the Deltec denitrator.
Results dun come instantly. Maybe use the Nitralock a lil longer n see how. If nitrate still dun drop, then stop using the product lor.
