Well, not that I won't buy more things, but I already bought one...well, technically eight presents for myself. I've been growing less happy with my Chihiros dosers. Their consistency just hasn't been as good as I'd like and I've had a few connection issues with Chihiros lately. So having read comments here and other reviews online, I decided to make my first Alibaba purchase and picked up 8 Kamoer X1 Pro 2 dosing pumps. With my recent struggles on my new garden tank and dosing the separate macros and micros, I'm leaning toward sticking with an all-in-one fertilizer going forward and so will only need one pump per aquarium. The cost of the pumps on Alibaba, even with shipping and import fees still only came to about $63 each. I plan to recoup a good amount of that reselling all the Chihiros dosing gear.
