okay this is a new tank, with a non mature filture yet, no fish involved, i know exactly what caused the algae and that was i went away for 5 days, so i dosed 5 days worth of ferts in one day and left the tank i come back and boom literally i can't explain it, only plant in the tank is cuba and is small isn quantity's altho the plant has grown nearly 10x in those 5 days the algae has grown nearly 1000000x here is a pic to explain what I'm dealing with, diatoms and a kind of hair algae, now i know that to much nutrients dose not directly cause the algae, but the cause is due to my non mature filter, i did exactly the same in my other tank, which has an overstock of fish lots of plants and a mature filter, 5 days worth of ferts and 0 algae i mean 0 not a single snippet of algae, lights are both on for the same amount of time 6hr a day, co2 injection 1hr before and 1hr after its lime green on the drop checker, altho i have upped it in my cuba tank so its now yellow.
again non mature filter i have 0 ammonia and 5ppm of nitrite, I AM NOT adding any ammonia into the tank this is coming from other source substrate, decaying plants or anything else.
all i want to do is help fight this algae initially to stop it spreading and to keep my plants as best i can without to much of a black out last time i did a black out i lost half my plants and i don't want that with this tank, the plants are the thing that makes this tank
i have just removed as much as i can and done a 100% wc but i can't get all of this algae, a black out is not an option so what should i do? liquid co2 came to my mind, i am reducing my light to 4hr should i keep dosing ferts? btw i am doing EI method
the algae involved is common in a new setup with a non mature filter, so once i have matured my filter and my plants take hold more i shouldn't have a problem but this is the tank now
