hi randy i am sorry if this question has been asked before but the search functon is down. i use a 20 gallon aquarium that sits beside my 110 gallon reef to hold freshwater for top offs. i use a float switch to control the water level that changes do to evaporation . would there be any problems if i added your calcium recipe directly to this freshwater so that when it refills the sump it also adds the calcium the tank needs. i am sure i need to find a balcance in this which would be the problem i suppose. i am guessing the answer would be no since the evaporation probably doesnt happen at an even rate everyday. is there another suggestion you could provide that would work something like i had in mind. i am using the salifert all in one now and although it works pretty good is getting expensive but i love the ease of use it provides. i figured though that if i already have fresh water pumping in daily i could also use it to provide calcium that way as well. thanks for any info you can provide. oh i guess i should mention my tank inhabitants my tank has mostly lps corals with a couple of softies and one sps. in the future i do plan on adding more montipora to grow on my overflow as well.
