Hard COral Diseases?

[whatcaneyedo]

I'm not a big fan of Hagen... A different test kit with units in ppm, dkh, or meq/L would make this a little easier. Also, make sure that your test kit isnt past its expiration date. Are you sure the test kit didnt mean ppm? If its 80ppm then your alkalinity would be 4.48dkh which is really low. You can boost it with baking soda using this online calculator http://reef.diesyst.com/chemcalc/chemcalc.html


"Alkalinity is a measure of the amount of acid necessary to reduce water's pH to the point where all carbonate and bicarbonate have been converted into carbonic acid (about pH 4.2 in seawater). In seawater, bicarbonate and carbonate provide nearly all of the alkalinity. Consequently, reef aquarists can use it as a surrogate measure for bicarbonate and carbonate which are taken up by calcifying organisms (Figure 1). The units of alkalinity can be meq/L (milliequivalents per liter), dKH (degrees of carbonate hardness), or ppm (meaning ppm of calcium carbonate equivalents). One meq/L = 2.8 dKH = 50 ppm CaCO3 equivalents. Seawater has an alkalinity of about 2.5 meq/L = 7 dKH = 125 ppm CaCO3 equivalents."

I can't believe the DkH is that low. I would find a LFS and get them to verify the carbonate hardness. Edmonton water is already hard( unless of course you are using RO/Di water) and plus fact that he is dosing with a calcium additive

The thing that jumped out at me in your posts were that you lost a couple crabs....how old and what brand of test kits are you using? First thing I would do if you wanna keep sps is invest in some quality test kits (salifert or elos) dkh, mg, ca and ph. ( I personally wouldnt bother with a phosphate kit).

yah all my kits are hagen ones.

didn't know those thing expired
