Bga In Planted Aquarium.

[jaycat]

Hi everyone,

I have a 75l 30" aquarium with amazon swords, 6 mini amazons, hair grass, ludwigia, wendtti, java fern, tall hydro plants. I'd say about 50% of my substrate is now covered. Beginning to have slight problem with BGA on the leaves of Wendti and Ludwigia.

Lights are one 18w daylite with reflector on for 12 hours. I add 1ml of TNT+ every other day. Prune every other week, water change every 2 weeks. No co2 as only have ladder system, and not convinced it's necessary.

Substrate sand with tetra soil under.

Stats:

gh more than 16 eg. off my scale!
kh 15
ph 7.6
amonia 0
nitrite 0
nitrate 20

21 small fish at moment in there. Tetras, corys and Otto.

Internal filter with flow pointing out into tank and an airstone.

Going to do water change tomorrow and prune, should I then do 3 day blackout?

Ideas appreciated.

Thanks guys

You could do a blackout, its very effective, but if you only have small patches, you could just remove them with water changes. I use an airline hose and just suck off the patches. Weekly water changes would keep it in check. I dont dose any ferts so when it appears I water change it away which works very well.
