So after playing around with a kalk reactor, dosing kalk via dosing pump and just useing ca/alk/mag additives I'm starting to learn towards just using 2 part and mag. I'm looking for opinions on rather I should leave my kalk reactor hooked up and running or just use more 2 part. There are several +/- to using kalk and I'm just not sure. My tank has been doing fine with a lower pH (8.0) so I'm not to worried about doseing more via a pump to correct that. My alk is also ok, I prefer a lower alk.(Not sure why, I just do) So my main needs are ca. With the amount of evaporation my tank has the kalk reactor isn't adding much kalk anyways, so is it even worth running it. The benefits to not running it would be- less opportunities for any heavy metals entering the tank, one less piece of equipment to maintain, and it would open up 2 outlets on my reefkeeper for use with other stuff and one less piece of equipment sitting outside my stand. Down sides would only be needing to run alittle more 2 part.(that I can think of) But 2 part through bulkreef is cheap so I'm not too worried about that. Any opinions or advice would be great.
