Hello all. I have always done water changes the old fashion way by bucket or large trash cans. However now as I step into my largest tank ever 240 gallon total system, I’m researching mixing stations. I’ve watched tons of videos and the idea seems easy and exactly what I need. HOWEVER I can hardly plug a cord into an outlet without screwing it up let along drill and glue and build one of these systems myself. I would be worried I would contaminate my water or end up with a large leak. I’ve searched and haven’t had any luck so here I am. Do companies sell pre-made or atleast pre drilled and bulkhead installed systems? I’m curious what something like that would cost. Anyone have links they can shoot my way or any ideas to get me in the right direction?
