Welcome to our forum.
I have to add Calcium at each water change and usually 1/2 way through a water change. I am told if you dont keep your calcium in line it can start to eat away at the plastic parts and make them brittle.Ray
I always get worried when I read threads about chemicals. I was never told to worry about calcium, not to mention my dealer does not even sell it. Also I read nothing about it with arctic. I here people buying digital testers and special test kits, and all kinds of chemicals. I have really had an easy year and a half with my tub chemicals, and this makes me feel that I am doing something wrong.This may sound bad, but I just add based on my initial tests. I maintained a 3 month cycle and observed what the water would do. Based on that material, once a week I shock, and fill up bromine. I have learned that setting the brominator to level 4 is the best. And once a week I add two capfuls of alk up. PH has never been effected since I have had the tub.I have not had cloudy water yet, my water never stinks, and I know that by month 3 to 4, I start watching for signs to change my water. I can usually tell me look and feel of the water. By using the micropure filter, I do not have to wash filter or add stain and scale or clarrifiers to the water. I have been enjoying clear water without incident.I have taken this approach based on my 15 years of expierence with fish aquariums. I have maintained marine reef tanks for the past 8 years. In the beginning, I added chemicals with digital testers and I would drip chemicals in to the tank to prevent any changes to the eco system. I was a fanatic. My friend who is into aquariums would do a water change once a months and fill the new water up with chemicals based on what he had determined appropriate for his tank. His tank looked 20 times better than mine. I switched styles and everything just started working better. My fish and corals were in heaven. Am I wrong in thinking that this is ok?? Should I be more dillegent with my water maitenance??? I just wonder if all this work just causes us to screw things up and makes us spend more cash on chemicals.
