Water Change

No, pura No3 lock won't reduce much. If your NO3 is super high, the best is perform water change. Don't waste $$ to buy No3 remover/absorber. They are costly and you have to change / recharge them often. It will even cause you more effort in maintaining.

Pura lock did not work for me. NO3 is still high after using it.

Resolve the problem from its roots. At the meantime, do 50% water change as frequent as possible.

water change is the solution for super high nitrate.

other stuffs like filter medium or no3 lock should be use only after water change to CONTROL the level.

it's cheaper to do water changes than using other method.

good luck.
