room temp 21c-29c and water 23-26c after every grow i clean my systems whit (carbonperoxide) it should kill everything that moves. same as used to blond hair but stronger liquid form. not harmfull to plants
Ok this is what I hear:
Rising pH
Brown film on roots
PVC pipe with running water
Silicone present in water
You have brown algae brother. Read up on aquarium forums if you really want to understand it. However the simple solution is light proof. I mean REALLY light proof. The PVC does let light in, just not enough for you to register it. However the algae will respond to very little light. Algae needs all the things you are giving it to survive: light, water, high 02 levels, silicone. This is like an aquarium set up, and really algae is a sign of living water. However in a garden designed for plants the algae will run wild, and brown algae in particular is troublesome in aquariums too.
So in short: cut out the silicone, and cut out any possibility of light getting in. Wrap the pipe with reflecting sheathing, and foil tape the joints. Make it look like a spaceship in there. Cleaning the system will be trouble as you need a dedicated algaecide like Physan 20, if its not a dedicated algaecide it will NOT kill brown algae. Anything tough enough to kill the algae will also kill ur plants - so be sure you wash and rinse AFTER using these products. Make sure the algaecide is GONE before starting again, or just get new pipes, hoses etc replace anything touching water and then start again SUPER light proofing.
Now you know, and knowing is half the battle
i got this liquid oxygen now and i added it but 1 died after it now i got only 4 left... sucks
