So it is completely my fault that I now have hair algae. I know it is due to a build up of excess nutrients and it happened whilst I was away on holiday and then when i came back, my pump to get water back into the tank broke, so i couldn't do the usual 50% water changes. So this is my fert routine - Sunday â€“ H2O change + 3/4 - KNO3, 1/4 - KH2PO4, 1 â€“ Epsom salts Monday â€“ 1/4Tsp - Trace Tuesday - 3/4 - KNO3, 1/4 - KH2PO4, 1 â€“ Epsom salts Wednesday â€“ 1/4Tsp - Trace Thursday - 3/4 - KNO3, 1/4 - KH2PO4, 1 â€“ Epsom salts Friday â€“ 1/4Tsp - Trace (optional) Saturday â€“ DAY OFF Except I don't usualy add the trace on Fridays. My question is - my plants are starting to yellow (not enough nitrate?) and get pinholes (not enough potassium?), so I'm guessing I have to increase these amounts, so how much would you reckon? It is a 240l tank with pressurised CO2 (not sure how much goes in, but the tester is lime green), eco complete substrate and about 3wpg. But my main issue, is that I am worried about the hair algae getting out of control, and how do I get rid of it because it is in my mosses and when I pull it off, it pulls all of my moss off as well!
