I just fixed my rodi unit. Took the load off of it by splitting the system and taking the sink faucet off the unit, filtering it separately.
With new filters it's banging out 0ppm water at a phenomenal rate. I didn't even have to change out the RO membrane and I have an extra in the fridge.
It's not a minute too soon. After that big die-off and new fish that died and I couldn't find, my tank is a giant snotfest. It's never been this disgusting, ever. I'll start changing 25-30 gallons every couple days for the next couple weeks until I've turned over at least 200 gallons of water in the tank. It'll be a pain in the ass, but I want it crystal clear and algae-free again.
I should be able to start filling buckets tonight.
