i keep a mixed reef. 90g display with approx. 40g. sump. minus the LR it's about 100g.
for years i have been dosing the big 3 manually and now with a SA doser.
i have never used a reactor and i am curious to how difficult or simple they are to use?
even with the stand alone doser, i need to test and adjust on an ongoing basis.
would this be the same with a reactor?
not really sure how they work?
