Came home to an empty CO2 tank (unexpected).
So i decided to go low energy for a while. Raised the lights to the ceiling (5 ft above the substrate), will add floaters. Only 2x 80W T5HO and 2 125 W HQI. See if this kills the BBA. Mostly swordplants in there so it should work.
update: lower light and lots of floaters. Trying to get a more natural feel.Liitle to no new algea, just some remaining BBA.
Lots less work, only give ferts 5 times a week and have continuous waterchanging on (app 50 liter /day).
In the end i want fewer plants in larger groups.
I have Hydrocleys nymphoides, Pistia, Ceratopteris pteroides, Phyllantus fluitans and Limnobium. DSC_5782_copy by Edvet, on Flickr
