I just was reading the side of my salt bucket and it says in the first bullet point that it has the correct calcium and magnesium amount to simulate natural sea water....
I just retested my water and cal is at 390 and ALK is at 7.4. I added more buffer and more liquid calcium. I will check again this evening.
Seachem Reef Advantage Magnesium™ is a concentrated (80,000 ppm) optimized blend of magnesium, chloride, and sulfate salts designed to restore depleted levels of magnesium with minimal impact to the ionic ratios found in natural sea water. Reef Advantage Magnesium™ contains no ammonia! This is a common contaminant in every liquid magnesium supplement on the market. Severely depleted levels of magnesium (below 800 mg/L) can cause depressed pH levels and an inability to maintain proper calcium levels. Magnesium depletion is commonly associated with the use of kalkwasser. 600 g treats 10,000 L (2,500 gallons).
Before dosing any magnesium (or anything for that matter) I would recommend you buying a test kit. Between your salt and the other things you are dosing, you might be fine.
I use the Kent 2 part calcium + alk and 1 galon of kalk a day. My calcium levels are great 430-450 but my ph is constantly low 7.9 8.0. Could this be a magnesium situation also?
Thanks RW, I am going to give this another week and see if I can get this kalk/ buffer/ calcium equation worked out. If I am still have trouble I will pick up a magnesium test kit and some magnesium to add to the system. I will keep you posted!
on another note...DSFDButterfly is going to be stopping by my place tomorrow to see my tank...you should get in touch with me too if you ever out in West Mesa, I like getting other people's take on it.
THats a good point about MAgnesium,although i dont suspect that is what is causing your troubles.DRop me a PM Tyler about this and i can give you some ideas for a DIY kalk/auto top-off system
