you need to run bennies and keep the water cold and dark. pond-zyme from petco or petsmart... aquashield... great white... heisenberg tea... any of that should keep the water clean assuming you are keeping it cold and dark. the roots do not mind the bottles of ice at all. as you can see root rot will destroy shit and warm water with nothing to control the slime is asking to get fucked.
I also suggest you stop using the floranova. it is too organic and a known trigger of slime blooms in dwc. I used it my first grow and had nothing but problems. often when we see root issues in dwc it stems from water too hot, using organic based nutes, or shit like superthrive and some AN additives triggering slime.
salt based nutes like flora 3 part series with bennies (or zone h2o2 bleach chlorine etc) and cold dark water.
Hey thanks for the tips, but what's bennies? After making a few changes I've got another plant dieing.... Very frustrating.
Also not running the flora mutes, not sure where that came from. I'm actually running fox farms trio in 4 bucket under current setup.
All four connected with 1" PVC pipe. The resivoir is just a tote but I was thinking of using an old ice chest to try and keep temps down(adding ice as well of course) I was looking at switching to Maxi series,only because it cost so much less than fox farms.
Thinking about trying to automate everything,with chiller/ heater and top off valve. since I don't want it to more time consuming. I have a 210g reef aquarium that I automated to make it less time consuming and I know when it comes to maintaining a hydro system it can get pretty time consuming.
