Hi everyone, I have a Red Sea reef 300xl and I am planning on going heavy in the SPS in a couple of months once everything settles in. Since it’s only 85 total gallons I was thinking dosing pump instead of calcium reactor and dose a two part like b-ionic(exact dosing liquid still being worked on). When comparing dosing pumps I found these and the price compared to the eco tech or apex versions seems too good to be true. Anyone have any experience with these? Any reason to stay away?
