Might add, I have sand bed with many inhabitants. I don't vacuum their homeI have no sump, how would I need to use this? Rhetorical. No way to turn down the suction... IDK. I use the python suction method into 5 gal buckets. I have a few buckets so it's a process, but I love "mettling" with wifely (husbandry) duties of my tank and friends lol
Him on water change day
Agreed completely..after this poll, I got frustrated with reg pump and found a portable transfer pump at harbor freight with plastic valves and a rubber impeller with window to see clogs.. I even have quick connects which make thing so easy....its self priming and powerful. It makes cleaning a breeze using a wide angle return nozzle it cleaned my outbreak so well on the glass and reduced to ¼ inch for corners and crevices and normal clear 1 inch tube with a scrub brush attached w zip tie for rocks..all right to sump in filter sock.. and also agreed..anything with cleaning a mid or larger tank while draining water, a bucket is no good..it fills way too fast. And if it doesnt..you dont have enough power (u may think you do..till u use this..lol) bad = Overflowing buckets if big tank..instant empty tank if small. Transfer pump to filter sock/sump.. the best.. and I've tried it all.I prefer an all encompassing solution for vacuuming the sump (40 gallons) and performing water changes. I find the vac storage receptacle is too small for any meaningful project on a larger tank. I use a transfer pump and hose. In my garage is the mixing station where I prepare up to 60 gallons of new saltwater. I use the transfer pump and hose to extract the water (and also vacuum the sump) into a utility sink. Next, swap the hose connections (use quick connects with shutoff) and pump the new water from the garage into the tank. Very fast process, clean and no buckets. 30 gallons every 7 to 10 days, 60 gallons once a month, vacuum the sump every other month.
For the sand-bed, I use a siphon into a 5 gallon bucket occasionally.
