Hit them with Zone from Dutchmaster or H2O2 and do it now. Follow the label on the Zone and use the max amounts. If you go with H2O2 buy the strong stuff and mix it down to 3% and than add 3ml per liter to start if no improvement in 24 hr, hit them with 4ml per liter and repeat in 3 days. That should do it. I run a tight ship also but this stuff happens. I have run at 62 and got slimed..

That white slime is a Cyanobacteria & it loves oxygen also thrives in dark places. I'm still unsure where exactly it comes from but my guess is my water source. I use a big boy RO with the big boy uv sterilizer & it still likes to show up so the only thing I've found that keeps it at bay is a microbe tea. I currently am using CS A&B & bud booster with some cal mag. When the slime appears I brew a 10gl batch of tea & add 8 gl into my 200 gallon system. The other 2 gallons I top feed directly onto the net pots. When first starting to brew tea I followed Heisenberg's brew witch is 15ml of Aqua shield per gallon,1/4-1/2 scoop of Zho,1-2 handfuls of ancient forest that I put into nylon pantyhose tied off & suspend into the water then add about 10ml of unsulfured molasses this is all per gallon of dechlorinated water. Use a large air pump & stone run under the ancient forest & let brew for 48hrs. It works! I've tried zone & H2o2 it helped but the bacteria always came back. After introducing this tea to the system your roots will turn a dark color,don't trip the tea is working within a few days you will see fuzzy new white shoots everywhere. Also if you feel the side of the epicenter it will be slimy if the bacteria is present once the tea takes hold no more slimyness. You must add new batch of tea every 3 days but only using a cup or two per module. I currently have been making my teas with caps bennies or triple helix brewing key to fungi & key to microbes with success. I hope this helps. I know it sounds scary adding organics into the UC system but it was the only thing I found that works my plants have never been as healthy.

I am running my 12 site 8 gallon uc system for the first time. I used a aeroflo 2o for my pre-veg and tranferred my girls into the uc when they reached 12 inches on top and bottom. My room temp is 70 degrees and thanks to my water chiller my water temps stay at a constant 65 degrees. I have covered all the exposed pipes and buckets with reflective insulation. There is zero light getting through to any water. I have only had the girls in the uc system for 50 hours and there is already white slime on the roots! I am using Dyna bloom at 4ml/GL and Cal mag at 3ml/GL with H2o2 at 1ml/GL. What could be causing this slime and what it the best course of action to take? I have read that this slime cant take hold if you keep your water temps down and you have plenty of oxygen to aerate your system. Please lend some knowledge to the new guy.
