Im running a discus tank with a temp around 28-30 degrees celsius.
I used to dose around 25 ppm kno3 and used EI. Looking at forums and talking to ppl made me wonder if i dose to much so i lowered the dosage to 2x5 ppm kno3 a week.
I got so much algae after this change so i thought ok its becourse of the sudden change. Plant growth slowed down a lot and so did the "curling" of fast growing plants. (kalcium issue plants cant move it fast anuff)
I tried to clean away the algae as ofthen as i could and changed water a lot but it just keeps coming back (around 2 weeks time)
So yesterday i cleaned the tank and decided to up the dose again so i added 20 ppm kno3. Today all fast growing plants got new runners (like glosso, h. polysperma) and no algae yet.
540l/ 0,5w/l t5
My small tank has lots of more light 1w/l but lower temp 20degrees celsius 10ppm kno3 and no algea at all.
Can this be linked to water temp ?
