I got slimed earlier this year by being lazy and not using anything in one of my systems for 3 weeks. I saw the slime start, and put off taking care of it until it got to pretty much all of my plants.
Here is how I won. It was easy.
First start a tea. Fill a 5 gallon bucket with 4 gallons of water (tap is fine but you need to bubble it for a couple hours prior to adding bennies to get the chloring out. Add 20mL unsulphured black strap from the grocery store, cup of EWC, 1 tablespoon OG BIOWAR root pack( www.ogbiowar.com ). Bubble hard (I now use an eco5 air pump by ecoplus and a 6" air disc). After 24 hours, tea will be foaming and ready. Unplug air pump. Let settle for a minute to let the talc carrier and EWC chunks fall to the bottom. Scoop the water from the top and use it on your plants and in your res. A 1/2 gallon pitcher will easily fit in a 5 gallon bucket for collecting the tea.
1) drain the system
2) fill with tap water. Add 16 drops of clorox bleach per gallon of water. let this run in the system for 2 hours.
3) drain and refill with tap again.
4) add physan20 at the rate of 3mL/25 gal of water. Let this run for 2 hours. DO NOT forget about draining this one after 2 hours. It is toxic.
5) Fill with fresh water. Add nutes at no more than 1.0EC. pH solution. Add tea @ 1 cup in to each plant site crown, and 1 cup per 5 gallons in to epi.
6) follow up with solution changes and tea weekly for remainder of cycle and all future grows.
My slime is gone. New roots started popping out in a week. I could have done better without the slime, but at 4 weeks (a week after being slimed), my plants looked like this:
And now they look even better. No signs of yellowing, shoot die back, stunted growth.. etc.
