What can I do about algae in water lines, will Algaefix work? The water lines are clear will black lines work better?
Replace your clear lines with black and you’ll be fine. Good old peroxide is the hydro growers’ friend.
It took me a while to learn how important peroxide is in a hydro grow, and that it needs to be completely recharged every 4-5 days, kinda like adding chlorine to a pool.
I messed up and used clear lines with my drip system. Gotta get black lines. I did disconnect them all and soak them in peroxide, though. Cleaned them up real good. But black lines. Definitely gotta go with the black.
Add 4ml per gallon Barley Straw Extract. I have a DIY RDWD with white PVC. Light gets in and 0 algae, extremely light algae growth on wet rockwool also. Works great, when you have a coi pond you float barley straw rafts in the pond to keep away the algae. Totally harmless and algae hates it.
After cleaning try adding beneficial microbes to your system.
I use Botanicare Hydroguard Bacillus Root Inoculant
Also pre-chill my water with 2 liter plastic cola bottles that I freeze the day before. Place in your reservoir or you can chill your replacement water a few hours before use.
