I'm assuming you mean the dual head pump?
I got it from here (back when the Canadian dollar was MUCH better lol):

Where did you get the dual head peristaltic pump?

Oops sorry

[daplatapus]

I got it right from Lockewell.
LOL,

Gobytron:

I'll explain this the best I can. Feel free to ask anything and/or criticize my thought process too. I'm learning a bit as I go and changing a few things I don't like about my existing set up. So, first up the 2 barrels: the one to the left is my RO/DI water. My RO/DI system will be mounted to the wall on the left - I haven't got it moved yet but probably will be by the end of the weekend. Right at the top of that barrel I'll be drilling the float switch that will turn the RO/DI on and off. Right now in my 30 gal bucket I only turn it on every 2 or 3 weeks for a day, depending on how fast the auto top off uses it up. I'm using a Tunze Osmolator as my ATO. LOVE IT! So nothing there will really change.
On the right is my SW barrel. Once a month I'll have to re-fill this and mix new SW. But it should last a month I figure. I'll get to that in a sec.
In the middle I have my Reefflo Dart. I have a line coming from each barrel, each with their own ball valve, tied to a "T" that goes into the pump. From the pump I go up and back into the SW barrel. Check my build page for the pipe I have inside. I just posted it this morning.
So when I want to fill my SW barrel with fresh RO/DI water I close the valve between the SW barrel and the pump, and open the FW to pump valve. Turn on the pump until the FW is empty and theoretically the SW is full. Turn off pump
Close the FW barrel valve and open the SW barrel valve and now you have a re-circulating pump. Into the pump from the bottom of the barrel and into the barrel at the top. Pour your salt in and let the pump run a while to mix. I'm thinking of having the pump on my Apex and have the pump come on once a day for a half hour to keep things mixed and aerated.

Now comes the part that will be new to me, the dual head peristaltic pump. It's rated at 100 gpd. So in theory I could actually change the entire volume of the barrel in a day, bit I'm going to be aiming for 3 gallons via a timed plug on my Apex. I'll be running roughly a gross water volume of 300 gallons a figure between display and sump. 3 gallons for 30 days is 90 gallons. My barrels are 100 gallons, so I should have some leeway. The pump has 2 individual heads so they pump exactly the same amount. So one will pump from that little 1/2" valve you see on the far right at the bottom of the barrels, through the dual head pump and into the return section of the sump.
Then on the other head of the dual head pump, I'll draw water from the filter sock area of my sump, through the dual head pump and into a drain I have plumber right where the pump sits.
So once a month, I'll need to re-fill the SW tank and fill the RO/DI water. Other than that I think that's it.
Ask away, I'm sure there's questions or comments

It works really well, spreads the food evenly and the AFS does not have to be set up on the DT.


I do small changes everyday , just so I do not have to have two barrels etc, Even though the RO/DI is connected to 2 barrels and a 5 gal bucket for ATO. All have float valves and shut off valves with J Guest fittings, so I can interchange, or disconnect quickly to move etc.

[FishyFishy!]

Here's mine

2 40 gallon Brutes, 2 150W heaters, 1 powerhead and a Mag 24 to tie it all together. Also use a 5 stage BRS RO/DI with an upgraded 150 GPD membrane.

Plumbed directly into my tank/ato upstairs. Probably the best thing I have done yet. Actually makes water changes fun!







You can see here where it goes left into the water change sump, or right into my ATO resevoir




I usually leave all the valves set so that I can just flick a switch upstairs and it fills my ato resevoir. When I want to do a water change, I just divert all the valves from the saltwater mixing barrel on the left. Best thing I did was run an extension cord up to my American DJ powerbar for the water change pump. After everything is set up downstairs, I just go upstairs, and turn the pump on.

Im working on a video that outlines how I do a water change. But I also have a video in my tank journal that shows me topping up the ATO resevoir if you want to check it out.
