CA at about 360

[MadReefer13]

my calcium has been low forever and i cant get it up.i dose with kent nano a and b but never any change.i have no clue what to do any help? cal is at 360-380 and i did two gallon wc yesterday on my 20 and added 6 drops each of a&b...an i use regular IO not reef crystals thats why i dose..switching salts once this batch is gone

6 drops is going to have a very negligible effect on your calcium in a 20 gallon tank.....according to the reef calculator (http://reef.diesyst.com/chemcalc/chemcalc.html) you should be adding about 5 and a half teaspoons to raise your calcium from 380 to at least 400 (kent tech cb and kent nano reef have the same concentration).

 

You should also measure your cal/alk consumption over the course of a day once you raise your calcium to the desired level, and then dose to meet that need

 

Other factors that could be effecting your calcium reading: imbalanced alk or magnesium. Do you have measurements for those?

I have alk.I'll test that now mag I dont

And so what your saying is I'm adding too less?

[MadReefer13]

Should I get Kent's calcium and just add that for now till I get it up?

 

Then g back to using the a&b

You're definitely not adding enough to raise the calcium from 360-380 up to an acceptable value. That would take significantly more than 6 drops. Whether or not 6 drops is good enough for maintaining calcium once you bring it up over 400 is another matter, which depends on the stocking of your tank. That can only be determined by measuring your daily consumption rate

OK ya I have thriving sps and my coraline is finally trying to grow...I have a green slimmer,tri color validia(sp)X2,purple monti cap,and another unknown sps that's a vary fast grower

I added 12 of just one as the reef calculater said to add just A.and tested right now cal was at 400 this time
