    Hi gabcas0319. Cyanobacteria can either be the result of too little nitrates in a planted aquarium leading to plants leaking organics in the water column. In your case with 10PPM nitrates not likely the cause. More likely just excess organics from other sources. Decaying leaf litter, fish waste, excess food and or lack of maintenance.


    Also low oxygen levels can contribute to this. Filter flow low. May need cleaning. Excessive temps due to summer heat. Also make sure no direct sunlight is hitting tank.


    I would manually remove / siphon off as much cyano as possible. Do a good all around cleaning of tank and filter. Prune any weak or dead leaves from plants. Light gravel vac. Water change and dose nutrients.


    If heat is also an issue try fan blowing over top of tank. Works fairly well at reducing temps.


    The fact you still test at 10PPM of nitrate indicates you don't have a super bad case. Really bad cases of cyano will zero out nitrates. Severe cases may require spot dosing with H202 or dosing erythromycin. You should not need this. Manual removal of cyano, pruning, maintenance, keeping temps down and water changes should take care of it. Let us know how you make out on this issue.


    Regards, Rob

    Low nitrate levels or not enough circulation often seems to get the blame.
