I'll look into those. The reason I was kind of looking at Apex is to control my lights, powerheads, and uv pump from the same system. Then add the DOS for additives and eventually I would love to do auto water changes. But, the price is so much. Every time I get ready to pull the trigger on a used Apex Jr or a DOS, I talk myself out of it as I only have two fish right now. I need to buy 2-3 more to start QT this week.Always take reviews with a grain of salt. HAHA
Seriously though, if that's how they worded it, it sounds like it was a user error with programing. It doesn't automatically split doses. You have to program it to do separate doses, or at least mine was that way, I suppose it might depend on the model. If it was meant more along the lines of the doser malfunctioned, every doser can malfunction. Yes, jebao probably has a higher failure rate, but many of us (myself included) haven't had any issues. Plus you get what you pay for a lot in this hobby. When I buy jebao I fully understand it might fail. If I have a problem with that, I don't buy it. For example, my main return pump is a Sicce SDC but my maifold/skimmer feed pump is a jebao pump. I knew when I purchased my return pump that 14ft of head pressure with a 20ft horizontal run was a lot to ask of any pump. I don't have Abbyz money, so I went the next best thing I could afford. I like Jebao, and personally have quite a few of their products on my tanks, but in that instance, with a higher than normal demand I didn't want to risk it. I started off with a jebao doser because I needed a doser for the tank but I couldn't afford to swing a name brand at the time and figured even if I only used it for a year it was a good $70 spent. It served me well, and eventually I upgraded to a GHL doser for reliability and accuracy. For me personally, I don't really see what I gained by going to a GHL over the jebao because I had a good experience with my jebao doser and ultimately feel like I wasted the money. If I were to buy a new name brand, I'd go with a Redsea doser or a couple of Kamoer F1's. If I was budget minded I would just buy a jebao without hesitation again.
Since you're just dosing AFR, I'd take a look at the Kamoer F1. Its a great price for a quality product.
