Dosing pump opinions

[eastlake]

So, the time has finally come that I need a dosing pump and at the moment I've got it narrowed down to two. A local shop I trust very much suggested the two pump master eshopps doser and I found a bubble magus three pump master doser, used, for a decent price. Is there major separation as far as quality goes between the two products, is it better to have the third pump for magnesium dosing or is the eshopps one best and manual dosing of magnesium simple? Any advice would be great as I've never owned or ran a dosing pump before.

I own the Neptune DOS and it is rock solid, and also owned Jebao dosers, and they lasted a long time. I dont know much about the Eshopps, but have read Bubble Magus tend to be innacurate. Not sure if that has been addressed though

I just ordered a GHL Doser 2. An upgrade from BRS dosers, I can't wait to get it.

I would probably say the Eshopps is the better product as I have heard a lot of negative reviews of the BM not being accurate. On that note I brought a brand new Jebao 4-pump doser two years ago and he has been during very good. I have had no problems or issues out of it and has continued to provide pinpoint accuracy. It was only $100 on ebay.

went with the eshopps, I am noticing though that after its been running that I'm getting excess air in both sides of the lines. Is this from air being taken in on the intake side? Has anyone else had issues with this? I'm pretty confident its not the pump, I just want to figure out why so much air is getting into the lines and how to stop it.

I had the same problem had to put one-way valves in on my Marine color Dozer it's just like the BM it so stopped the problem

I'm having the same issue. Air in the lines. Where did you put the one way valve? At the end out the output of on the input line before the intake pump?
