That is a good deal. I use two of these to automatically dose my fertilizers in my 37g. I was able to sit them up without any difficulty and they have been wonderfully realiable.

They are described as dual. Can they pump from two nutrient reservoirs?

I don't think so. They do have a video that you can watch. I use one pump for my macros and one for my micros. They are virtually silent.

No, they describe them as being used to dose 2 part for reefs. You need one for each mix you plan to dose.

I started using peristaltic pumps to dose macros and micros over the summer, after I switched to a travel-intensive job. As anyone who saw my tank in February knows, I'm obsessed with having things hanging up over my tank rim, so I plugged the tubes from the pumps into my co2 reactor. (The third tube you see is the co2). This keeps my tank clear of clutter but it did introduce a problem. Once you stuff that little tube through the PVC, the orifice is pretty small. The micros tend to gunk up in this hole, blocking flow. I'm dealing with the problem (I think) by diluting my brew a bunch and increasing the daily dosage of the diluted brew.

That looks nice. No leaks?

<fingers crossed>

No.

I use CO2 tubing--the thick walled kind--and yank it through a hole that is small enough to create a tight seal.

I realize this is light years too late, but why not just do a wet/dry?
