Jehmco Has the Solution to My Water Change Question!

I attempt to explain how I can now change water to 10 tanks at once using some products from Jehmco that I bought with my own unsponsored money.
Not talked about but still part of the water change system: pvc 3/4” male threaded attachment, 3/4” pvc pipe, Christie’s PVC glue and purple primer, Python hose and Python female hose clamp thingies, and a brass 4 way hose splitter found on Amazon.
