Just out of Interest, how do PPL feed there calcium reactor. when I got my first Calcium reactor the TMC 1000 It was gravity fed and never found any Issues, since then its been a few years setting one up and I fed the Deltec via a Tee off the phosphate reactor feed pump. I had a few issues with it stopping. I have just set up the new one the same way and I'm now debating to gravity feed it or Via a D&D peri pump.
so PPL how do you feed yours and any issues you have come across wether gravity-Tee-Peri pump and what peri pumps you use.
