Hey all.
Touch wood my aquarium is currently pretty algae free apart from green spot which I cant seem to shift.
Going on Jame's planted guide seems it could be low co2, low phosphate, poor water flow, to long a photo period or a combination of them.
my tank is 200l
I think I have flow sorted. I have a full length spray bar running off two filters and a power head. I can see good plant movement in all parts of the tank.
Lighting is from 2 30w T8 tubes on for six hours a day.
injected co2 on for 6 hours a day, comes on 3 hours before lights and drop checker is bright yellow at lights on. I cant inject any more co2 at all as I'm right at the limits for the fish.
This leaves me with phosphate. I'm EI dosing and have been using the recommended mix from aquarium plant food.
on my last mix I tried adding more potassium phosphate "recommended was 1tsp, I used 6tsp"
but It didn't seem to help with the green spot algae.
Is there any thing else I should try?
Do you think I need to add more potassium phosphate? It seems like a lot?
cheers for any help.
