I gave up on my diy cloner for now. I kept finding a slimy pump cord. So its getting to warm and growing bad stuff imo. Just posting so people dont overlook it. When your checking for sliminess, run your fingers on the cord to your pump where its submerged, because it could be a point of failure.
I even tried a timer with 1 minute on 5 off and it made no difference. Within days it was slimy. I guess I need a smaller pump with a bigger cord, but I had just replaced the pump and a smaller one would mean I need less nozzles, which means rebuilding the whole thing anyway. I’m trying to make a simple 5gallon bucket setup with an air stone this morning.
