Goldfish Garage: A Two Car Fishroom: This is one hoses I use to change water quickly. It's a 1.5 inch pool vacuum hose with military spec cam lock quick disconnect fittings. I call them the baby blue anaconda (Python water changer joke, comment if you're nerdy enough to get it!), baby because I have a 60 foot 2 inch blue hose called the blue anaconda. Attach a simple pipe hook and you can drain a 220 gallon tank in about 5 minutes by siphoning. I have several sump pumps and a pond o vac 3 with this same connection so I can drain, pump and vac water, which are daily tasks for me. #goldfishgarage #goldfishunion #goldfishpond #goldfish #goldfishunion #goldfishkeepers #goldfishbreeder
