"MG will not help increase your CA levels. it will only make the CA available to your corals adn coralline. "
You got this wrong.
Without correct level of Mg i doubt you can Alk to 9 dKH and Ca to 400 ppm. I think its called Mg poisoning. Mg forms a complex around Ca ion which stops it from combining with carbonate hence you can reach these levels of saturation without the calcium precip .
Its very easy to correct the imbalance once the levels are known
Yes. you are correct in the chemical analysis. however, just adding MG will not up your CA levels (that is what our friend was mentioning).
the combining thing is exactly what i said. only when Mg is in correct propotion (3x times CA) will it allow the ca and carbonate to be available.
but just dosing without testing is risky.
btw a bit tangent here, what will you say to this (my tank actually)
Alk - 5
CA 300-320 (but amazing coralline growth)
no amount of CA dosing (kalk slurry) will raise CA by more than 5ppm a day.
but, I have better results using Tropic Marine bio calcium.

I know alk and CA are low. that was not what i was asking
I use sodium bicarbonate and purposely stopped and let alk fall because i suspected it was blocking my ca from going up.
I know PH will rise with slurry my friend
but that is not a problem as long as the change is within 0.2 points.
anyways, what i was asking was
I dosed slurry of 1 teaspoon calcium hydroxide (analysis grade) in 300ml of water daily for 1 week.
why dont i get a rise in CA even though i dose slurry every night?
i purposely reduced alk from high (8-9+) to current 5 as i thought this was the cause of my CA not rising with addition of kalk slurry.
I doubt the testkit is wrong
I get better results with tropic marine bio calcium
I am sure of the quality of the kalk as i tested it with a test kit.
can you tell me what can possibly be wrong when i dose kalk slurry?

T5 are really good optioin make sure you mix some actanic lighting as well it will inhance the colour of Zoanthid's ....
Arcadia T5 is one of the best option i would say but on expencive side... but realy satisfys with the output.....
