Hi can anybody expand on the Hydrogen peroxide idea at all? I do really want to rid of the algae, but don't want to risk any issues with my soil as I am about to plant £100 worth of plants into it!
Another suggestion that was mentioned by mnemenoi in this
other thread I started, was to dose a liquid carbon source. Does he mean to spray the algae directly with it before filling, or just start dosing it regularly into the water once the tank is filled, or both??
The other question this raises is wether that means I would have to continue using the liquid carbon? I hadn't intially planned on dosing any added carbon to keep it as low maintenance as posible, but since then, I found I can get 2000ml for £22 (based on 4ml per 200L per day) which works out at 500 days worth (more economical than I first thought).
What factors should I consider when deciding on whether to use the liquid carbon on a soil base low tech tank?
