Hey thanks very much and what an amazing amount of comments. I’m picking up on yours as wanted to say I’ve just done some tests.Welcome!
I use the 123 (mix my own, which is cheaper by 2/3rds). Your best bet would be to stabilize all your parameters where you want them before moving to dosing regimen. The ratios that each is consumed is pretty consistent and I've maintained rock solid levels by dosing the three in equal amounts.
I'd start by making sure your salinity measurements are correct. Something has pushed your Ca high. Could be dosing another product, salt mix or higher than normal salinity.
Once you're sure the salinity is right, re-check the calcium level in the tank, as well as in freshly mixed water to get some clues why the Ca is high. Lower the Ca either with water changes, or by letting it come down on it's own without adding anything that increases it.
Increase your Mg to closer to sea water levels. Somewhere between 1300-1450 is good.
Keep dosing whatever you are already doing to maintain the Alk, so that the Ca can continue to come down. If the alk supplement you are already using contains calcium, then just plain baking soda is a fine substitute for short term use.
With a consumption of only 0.1 dKH per day, you probably will only need a few ml. Dose less than you think you need, and correct it manually until you find the point where it's balanced and you no longer need to make manual corrections.
salinity is 1.025 always has been.
my Ca 520. Mg 1200 Alk dropped exactly 0.1 a day and now at 7.6. (I’ve stopped dosingfor now)
I’ve never had high Ca before. I started dosing Alk and worked out the right amount and it stayed at 8.4. It’s only since I started dosing Alk that my mg has dropped and Ca shot up. I stopped dosing as read that if you dose Alk but not Ca it causes Ca to rise? Don’t really understand how I’m meant to maintain Alk if it throws Ca out. Hence why I bought the Aquaforest 123 but now I can’t start using it as My parameters are out.
Hope that makes sense.
