I am looking for a reliable calcium reactor for my 120 mixed reef w/ a 40 gallon sump... However the catch is I am not looking to spend too much money being I have a hungry little 3 month old at home... I have been dosing liquid reactor for a couple months but would like to have a more stable setup... Any recommendations for me? I will also post a WTB thread in the for sale forum and see what everyone has...
