Might be a silly question. But Iāve been doing my water changes with a hose the past few weeks without issue. Run the hose from the tank to a close by walk-in shower, itās a breeze. As of last night Iām having a scientific troubling. Water will no longer flow through the hose. I checked the obvious, kinks, nothing. Hooked it back up to the spout and ran water through it, runs through just fine, no clogs. Tried a whole different hose, same thing. Literally the only thing Iāve done since the last time I did this technique was install a water heater, my water is now 3Ā° warmer - surely temperature cannot affect this. Iām at an utterly confused loss, ha. Any ideas?
