Not sure why it got off the idea...but this isn't for siphoning...I was kinda meaning a pump for putting freshly made saltwater INTO the tank from your brute trash can.
Or mixing new salt...way better and cheaper than a Mj1200
IMO, leave your pump set up with the hose for transferring water to the tank or from the tank. Drop the pump into the tank for removing water, in case you hadn't thought of that....works great, but you might need to put a 90º fitting on the hose to prevent kinks. :)
In my old
A Water Change A Day... thread
I did a lot of water changes. :)
In the course of things I tested
a lot of ways to mix saltwater. From airstones to flow pumps to a mixing paddle, and every permutation.
Using one pump for mixing and transfer is possible, but not really ideal and a little too much bother reconnecting and detatching the hose when it's not really necessary.
If you're going to use a pump for mixing, use a flow pump with a propellor – their mounting options are always superior. Performance (mixing time) is better with a flow pump too. I've used a Seio 1000, a spare Tunze 6045 and a gen 1 Hydor and all worked well.
So if you want to use a pump, set up something like this where the pump is aimed at the bottom of the mixing container:
But if you want the best way to mix saltwater, a paddle has to be it – and this is how I do it still even in a 55 gallon drum. Inexpensive, no power and no setup required, quick results, works in any size container:
