I just seen there is light coming into my rez and my new rez. Its like the old rez failed bc I had it for years anywhere from 3-7 years. The new rez exactly the same has light coming in the top and the roots look brown all of a sudden when they were white.. I put mylar on top of the rez and its a lot better. So could I have gotten root rot/pythium in one of my plants and effected all of them???? Its like I got it from one tent/rez and it got into all of them and effected all my tents rez's in my basement. No way all my rez's went bad at the same time.I mix the same 3ppm strength to everything. I add it to my RO water jugs (7gallons) to keep them sterile. Then I don't have to think about it for a while.
I used a local brand in northern Europe but I'm currently situated in Thailand so I use the local brand they have here. I'm used to using bleach and what I do is check the biofilm in the reservoir to see if the bleach is doing what it's supposed to do, removing it. You should feel plastic and no slippery biofilm(algae) on the inside of the reservoir. If it's still there you increase slightly.
It's very hard to overdo it with bleach.
Rubbermaid Commercial BRUTE Tote Storage Bin with Lid | eBay those are some of the rez's I use and I also use the hydrofarm ones for growing. ITs like they all of a sudden went bad and let light through the lids and the new one is doing it too like it wasn't made as good.
I think I might have to start all over with new rez's buckets and just start from scratch.
