Pump for water changes

1025 Views 9 Replies 6 Participants Last post by  rgr4475
Thinking of getting a couple of 55g drums pretreating the water and keeping them in my basement for water changes. For water changes, I can siphon the water from the fish tank out of the window and then looking to pump the drums full of water into the tank. Anyone have a similar set up? Any ideas on economical pumps that would work?

For that much lfiting you will need more pump than we often use. You need to look at how much distance (head) from the tanks in the basement to the tanks. Sounds like it will be something like12-15 feet. That requires a pump to fit the situation. I found Catalina Aquatics has a line of pumps to fit most jobs but I'm sure a search will finds bunches more. Normally pumps will be rated to pump "X" gallons at a given head and then as the lift increases the GPH decreases.
For the price you could almost consider a small jet pump for a sand point well.

Not sure if that would be applicable, but just a thought.
I use a 21 gpm drainage pump. Picked it up at local tool store. The one they use to drain man hole covers with. It will get your water to where you need it. I just made a few turns out of pvc to slow the flow down when pumping into tank.

I remember chiming in a while ago to a similar question. I have a 125g and here's how I do my WC's.

1. Add salt/Prime to a 20g Rubbermaid and let that fill at the kitchen sink.

2. Simultaneously gravel vac/Python the tank.
3. Use a submersible pump to to pump out old water (takes a minute) -

4. Use submersible pump to pump in new water.

Takes about 30min to WC 40-60 gallons.

Just a heads up warning for those using Rubbermaid type containers for water.

Most are not made to hold water but for dry storage. That leaves them prone to leaking in the long term. Watch the corners and bottom edges over time. As they are filled and emptied the edges flex each time and at some point they will start to show signs of stress. When you see discolored marks at the edges, that is your warning to stop or be prepared for flooding. I'm not against using them, just be aware of the potential.
Thanks to everyone so far
I use a mag18. I wanted something that would get it done quickly, so you could probably get away with something smaller. What's the head height? You could get a mag9.5 that would pump 400gph at 10' head for about $80. Smaller, cheaper pumps usually have a small max head, so may not push water from the baserment to the 1st floor.

Hopefully not too late because you've purchased already. My storage is in the basement and I pump to upstairs. I use the all plastic sump pumps found at most lumber yards or farm stores. They have a bottom water pickup so they can pump down to almost a 1/4". They are designed to pump out of a pit in the floor and up and out of a basement, so the head pressure is not a concern. They come with a garden hose attachment you can screw on to the outlet. That's what I use. They cost around $50. I replaced the mag 2400 I was using because even though it moved a lot of water reducing it down to a hose size caused a lot of water pressure blowing stuff all over at the aquarium. Even though it takes alittle longer I like the flow of these pumps better and you can't beat the price. I have two, one for a backup just in case but after more than two years I don't think I'll need it.
