Algae Controll

[aaronnorth]

Easycarbo/ excel will not kill BGA as it isnt really an algae.

Best way it to do a 50% water change while removing as much algae as possible, then cover the tank up for 3-5days (depending on seriousness) without feeding or peeking etc and stop any fertilisation and/ or CO2 injection. After the blackout do another 50-70% water change to remove the dead algae spores.

This should clear you problem. It may come back so you will have to look why you are getting it in the First place.


dirty filter - can cause ammonia spike
ammonnia spike - lots of organic matter
general lack of maintenance
poor flow/ circulation - in a planted tank we aim for 10x turnover to minimize dead spots, i am unsure of how much decor (rocks & wood) you have in your tank which could be slowing the circulation.

WHere the BGA is growing, jow is the flow in that area?

i dont think it is bga that was just the closest match in your link. ist like very short fine green hair on the substrate in 1 very small area by the entrance to my kribs cave which is situated in 1 of the calmer areas of the tank. its literally only a small area around 2 inches square . tank is maintained weekly with 30 to 40% water change ( upping to 50%) weekly gravel vac filter is kept well maintained too cleaned every 3 weeks pipes every 4 . it never seems to spread any further im just a bit concerned it may suddenly 1 day "explode"
