Hello everyone! I hope you and your tanks are doing well. First off let me say that I am very happy with my Rena and I am by no means bashing it as I have two of them and they both do an excellent job. The only thing I ran into (and this is probably just my dumb luck) is that during a water change I accidentally moved my intake a in a way that the top connecting piece came apart from the two lower connecting pieces, and one of my two brand new baby Rotkeil Severum got sucked into my intake, and by the time I noticed him/her missing right after finishing my water change it was already too late. It was such a shame too because they were both doing so well in there and getting along well, ARGH!
I am going to replace him/her in the next few days but after that I took both of my intakes out and used a thin layer of silicone to bond those pieces together so that I can hopefully avoid that problem in the future. Next time I buy a tank and buy a new canister filter, I will bond the top two pieces together before I even put it in the tank so I don't have to scrub the area clean beforehand again. Just some food for thought, hopefully other people haven't run into this problem and this is just a Murphy's Law thing for me, but I would hate to see anyone else lose a healthy fish without warning like that!!!
