"Towel" is in a 2.5 gallon "mini bow" tank with a small hydor 7.5 watt heater (on a rheostat "dimmer switch to adjust the wattage)
I am having a heck of a time keeping the algae out.
I purchased "tetra algae control" and i am dot sure of the dosage... I think it says 1 drop per gallon.... So I added 2 drops
replaced the filter, took out the plants and washed them and lightly vacuumed the gravel.... and now 3 days later the algae is back.
How many drops should I use of the tetra algae control.... (btw the tanks temp is between 79 & 83)
