Green algae in my water tanks

[Diyandimitrov]

I have a green algae in my tanks I clean them often and. I finally cover then wirh black plastic so I can block the light and start to fight with the algae. But for whatever reason I keep having it. Idk actually how dark it shoud be.but I also wanna ask its there something wich I can put in the tank with every watering wich can kill the algae? I heard thw gypsum can help me but im not sure if I can used every time when I watering my plants. Cause I remeber it was hight % of calcium. So I'm afraid im gonna put too much calcium an lockout some other nutritions. Any one have a idia how to kll that algea once and forever? I also heared thw oxygenated thw water it will help but I looking for something else? Thanks

Hydrogen peroxide is what I used to negate/reduce algae.

not hydro guy but algae needs light to grow, cut light from equation and you are halfway there but you need more than plastic sheeting. Can you black out with osb, sheets of tin or a tin roof? Whatever but much beefier than 6 mil of plastic

prolly need to blackout first, clean the tank and go with enzyme like hydroguard or Z9

Hydroguard anz z9 add them every time when I have water in the tanks ?

I think they contain same active ingredient but hydroguard is for US while Z9 is the Canadian version. Not sure how well they will work if you don’t eliminate the light tho, but seriously Skirk knows hydro stuff much better than I do.

If you're in Canada there is a product called Enzymes Komplete that will take care of that issue for you. I use it at 1ml/gal with success. It's just a made in Canada version of the other products that were mentioned. Be careful to not add too much though, there was one fellow here that said it killed his grow and it may have but for me it's been working for a couple of years now. At 1ml/gal it's not the worse expense and well worth it IMO, it is also compatible with h202. Enzymes Komplete also does a fantastic job of aerating the water.

If you're not in Canada then you can ignore everything I've said .
