Just got my first one...and it's also my first side hole fill tank. AWESOME! I got the polypropylene type (budget and wanted to check it out before committing much money). I am impressed...and very happy. I'll be getting more of these...and probably some Pyrex ones, too! Ray seems like a great guy! Okay..so here's the question (probably answered elsewhere, but thought I'd ask anyway). These have grommets for end caps. They are kinda hard to get on and then get the carto in them. Wondered if anyone had any tips or "systems" that work well for assembling these guys with the carto into the tube? I muddled through, but I'm sure there has to be a better way!
TIA!
