i use multiple cloners every day and have for years. you must bring in cuts or never even rinse it because that's not a typical experience at all and I've turned at least 30 people onto aero cloners. the only faulty part is the sprayers and they cost less than a dollar each and you lose maybe 8 a year. so because you can't clone in your cloner after a year you assume its damping off pathogens and can't be removed and that that happens to everyone else? surely that sounds ridiculous to you too.
honestly, either a freak incident or something you do because countless people use aerocloners and don't destroy them. most convert old ones into rdwc or just grow plants in them. rapid rooters also cost ridiculously more over time considering $20 of sprayers and nothing but water will last 5 or more years with 100% success. i can't tell you why yours are failing but that is absolutely a one in a million situation if you actually had to throw out an aero cloner after bleaching. most people don't even clean their aeros in my experience and still don't have problems. just some algae. besides buying your own pump and sprayer attachment every year is cheaper than rapid rooters also.
