High light, non-co2, floating plants = no algae blooms?
I was thinking how usually high lights (defined as higher than 3wpg) without adequate CO2 will result in an imbalance in the tank, causing algae blooms.
To counter this without reducing the light levels, is it possible to have floating plants curb algae blooms in a high-light non-co2 tank by absorbing and diffusing most of the light?
The floating plants will draw CO2 mainly from the air, and nutrients from the water column.
The submersed plants will receive less lighting due to floating plants shading and diffusing the light. The submersed plants will have growth typical to low light, non-co2 systems.
Fertilizers will be dosed according to a low light, non-co2 tank EI schedule.
I am planning on experimenting with this idea, but before I go through with this, does anyone have any input/suggestions?
I will use cardamine lyrata and duckweed in a 55 gallon tank with 3wpg (2x 55w PC, 2x T5 NO 28w). Cardamine is slightly submersed but should block lots of light. Duckweed will block a lot of light.
