Hello everybody,
I have algae problems in two of my aquaria. I have blackbeard algae in my community tank, and cyanobacteria in my blackwater aquarium. The blackbeard algae has gotten completely out of control and is everywhere. The cyanobacteria is contained to lower parts in the substrate and a small part on the wood visible in the pictures. I have tried using eheim algozid in both of the tanks in the appropraite dosage for the respective algae, but this has had little impact. I do a 30% water change once every two weeks in both of my tanks, and I also top of the blackwater aquarium once a week, since it has no lid and therefore loses more water to evaporation. the lights are on 7 hours a day using a timer. I started using a plant fertilizer which contains nitrogen and phosporus based on advice from my local fish store, and I add liquid carbon dioxide (Flora Grow Carbo) once a day, also on advice from my LFS. But I have seens little impact on algae growth from these measures. And the added nitrogen from the fertilizer has actually spiked my nitrite and (I think) killed my gourami. I have measured the following water parameters today before the water change using drop tests:
Community tank:
pH: 7,5
KH: 11 DH
CO2: 13 mg/l
NO3: 30 mg/l
NO2: 0,4 mg/l
NH3: 0 mg/l
PO4: 0,5 mg/l
GH: 13
Fe: 0,08 mg/l
Temperature: 23
Stock: 12 neon tetra's, 2 molly's
Blackwater aquarium:
pH: 7,5
KH: 12,5 DH
CO2: 14,5 mg/l
NO3: <10 mg/l
NO2: 0 mg/l
NH3: 0 mg/l
PO4: 0 mg/l
GH: 14,5
Fe: 0,05 mg/l
Temperature: 25
Stock: 1 Betta Splendens
I have added pictures using the following imgur link:
I was wondering what I could do to reduce eliminate these algae. Any tips/advice is appreciated.
