Ok so I'm an idiot... how do you clean your tanks? I'm starting to get a nasty taste out of mine - changed the carto, juice... saw a little bit of residue where the carto hits the top, cleaned it with a q-tip, rinsed in hot water... taste is still there. I didn't want to use alcohol for fear of cracking. I read the maintenence thread on IVC, but didn't see anything on cleaning.
Thanks all
I would mix vodka and water.....or vinegar and water....Give it a soak.
I use dishsoap and hot water. Clean mine like that every time I change a carto. Top and bottom cap and poly tube alike. Never had a juice residue after cleaning like that.
And just FYI, after I fill my tanks, I wipe down the whole outside with 91% isopropyl to remove any residual juice, and I've never had it affect them (the polycarb or the acrylic). I'm not saying you have to soak them in alcohol, but its not going to hurt them.
