Hi, Tank specifications - 240l tank Water - 26 deg C, pH 6.0, ammonia, nitrite and nitrate were all zero when tested this morning. Lighting - 2 x 40w T8 bulbs (the standard lamps with a fluval roma 240 setup) on for 8 hours per day. CO2 - DIY yeast setup, delivering roughly 1 bubble every 3 seconds, drop checker is a nice lime green colour most of the time. Filtration - Fluval 305 external rated at 1000L/hr, UV steriliser pump rated at 800l/h Fertilisation routine - 6ml TPN+ per day, 20% water change once per week. Im having some fairly bad algae problems in my tank at the moment. Ive got BBA on a big java, hair algae on the glass, plants and stones, diatoms on the glass. Plants are very healthy and growing nicely. Im using a DIY yeast setup, but am really struggling to get a steady and constant level of co2 in my tank - i guess its the nature of this method. I cant afford to go pressurised at the moment so my question is... Would doing away with the yeast setup and i guess going more low-tech help me reduce my algae growth? Im prepared to accept slower plant growth if this is a side effect, just sick of having to clean the glass and stuff so much. Would i still keep up with the TPN dosing?
