I used one bag of bio active gravel, plus added fritzzyme live nitrifying bacteria intially. I weekly add easy green and use fritz completewater conditioner when adding water. I planted tank on the 10 th, added a small amount of water that evaporated. Yesterday, I cleaned tank taking out 1/3 of water. That’s when the cloudiness and increased nitrate occured, it is sublte. Trying to send pic. Thank you!
