    High Readings

    Ca deposits without adding Ca?

    I know you can get calcium deposits, if you add excess Ca or add it too quickly, but why would I be getting calcium deposits without adding anything to the tank? I'm using Reef Crystals, and have normal water quality, as far as I can tell. Can someone tell me what might be going on? Could the...

    Huge swings in Mag & Calcium on a DAILY basis. What's going on?

    Hi guys, This forum has been very helpful with all my beginner questions and was hoping some of you might shed some light on my ongoing problems with water chemistry.

    Red Sea Foundation A Powder - HEAT

    So I've been advised that mixing Red Sea A (powder) in 2L coke plastic bottle will resulted in the plastic bottle not being able to handle the heat which is emitted by the stock solution. Is this the case?

    24 hour 2 part dosing?

    My current 2-part dosing schedule splits Alkalinity and Calcium into 2 separate times utilizing the Reeftronics program generator to program my Apex and BRS 1.1 mL peristaltic pumps.

    Another CA test gone bad

    I've read about others experiencing this but didn't give it much thought as I go through my tests well before their expiration date. My "old" -- less than 1 yr -- was off by 170 ppm. It was giving me a reading of 400 when I was really closer to 570. That got me to thinking, how many have...

    Saltmix Parameters bring on the test results

    There was an excellent thread put together quite some time ago now by Billybeau1 and hilgert.
