![]() I use just use a siphon with an irrigation valve to control the driprate. Took about 4 weeks to fully cycle then the nitrates dropped like a rock. I have this on my SW. For the hose going in and out, I drilled through the top then using a torch I warmed up the factory hose connections and sealed them off.
