Dosing pumps

[Ab129]

So I am starting to pay closer attention to maintaining my water parameters and have been calculating what I need to add to keep magnesium, alkalinity and calcium stable and at target levels.
Now I am considering purchasing a dosing pump so I don't have to keep track and remember everything on my own.
At first I was looking at a $500 ghl unit but now I see jebao 4 unit models for well under $100.
Are these inexpensive models reliable?
I usually tend to go with the more expensive choice but this is a huge difference and I don't really need to spend the $500 right now.

I like the jeabo personally I have used it on my tank for the past few years with out problem. I have always wanted to try out one of those GHL ones also and see the difference. But if you calibrate the jeabo and keep up your maintenance it is great.

I have run the Jebao DP-4, four years and counting now.

I use a pair of BRS 1.1ml dosing pumps on both my DT and FT. Paired with digital lamp timers from HD they are bullet proof IMHO.
