Adding Calcium Chloride

[lbbudle]

I managed to get my aquarium out of balance by adding too much buffer so now I have 200 ppm of calcium and a alkalinity reading of 5. I have been using calamax in addition to adding calcium chloride (about a teaspoon and a half per day) to a 75 gal tank with sump. I done this for the last four days. So far I haven't seen any movement in either of the two readings. Is the dosage amount correct or should I be at a higher level or is it just going to take an awfully long time? Thanks
:rolleyes:

I recently asked the same type of question to Randy. You will need to add a lot more of the calcium chloride to make a dent. Randy gave me a great link that helps with figuring out how much of a product to use and what its effect will be.

I had a reading of 300 ppm calcium on my 75 and it took 15 tsp of Kents turbo calcium ( calcium chloride ) to raise my calcium to 390 ppm.

I have a diy filter box that is the input to my sump/refug. With strong waterflow throught it.

my calcium went from 250-300PPM to 400ppm over a three week period and has remained there for three months. All I did was switch to crushed oyster shells as the filter media.

I've never heard of calamax. What is that?

[lbbudle]

Calamax is just another two part supplement of Ca and alk. It's made by WM and it just another competitor of ESV's Bi-onic. Good stuff if you don't add anything else like I did.

lbbudle:

You'll need a lot more than the recommended dose to raise calcium that much. The calculator above sill show you how much.

Bob:

I don't know what happened in your case, but oyster shell wouldn't normally be able to raise calcium levels like that, unless the pH or alkalinity were very low.
