flushing

has anyone ever used humbolt royal flush,if your growing in dwc you may not want to use this,I followed the instructions on the bottle and my res started foaming like crazy,if I turned down the air the foam would slow down so I drained it replaced the res with plain ph 5.8 water,the foam is still in my res just not foaming out like it was.has this happend to anyone else

can you post some pics? I had a similar problem when I was running Hygrozyme and H2o2 at the same time in RDWC system. What kind of fertilizer are you using ?

stop using flushing products there overated, use plain water and replace the water every three days for 2 weeks you will end up with
some of the cleanest shit
