I have been considering dosing calcium. I don't know what I need to do it though. Could someone help me with a product name (generic) and chemistry name please?

I read that one of the signs of a deficiency is twisted, irregular, or yellowing growth, and some of the edges of my leaves are a slight yellow. I don't seem to have any extremely irregular growth, except what was there when I bought the plants. I just want to catch the problem before it gets bad. Is there a test kit I need to get or is it even worth it? I also think I'm going to add some crushed coral to my filter, so will that add calcium? Will this be enough?

Thanks for the input.

I also want to add that I just started dosing Flourish, Flourish Potassium, and Flourish Iron 1 week ago. I dosed again mid-week. Should this product give me the amounts of calcium (or possibly Mg) that I need to get optimal growth? Should I just wait a couple weeks and see if I need additional amounts or get them now? Maybe it hasn't had time to correct itself yet, but the nutrient levels are OK now? Any insight?

I have a standard 20 gal with 40 watts of light. I'm running the Nutrafin (Hagen) DIY CO2 canister, but plugging it into my Duetto DJ100 internal filter. I'm averaging about 10ppm CO2. I have planted about as much as it can be without looking crowded. I have majority Crypts, with some Swords, Anacris, Micranthemum, Java fern, and Anubias. I am dosing Flourish 1mL 2x/wk, Flourish Iron 5mL 2x/wk, and Flourish Potassium 5mL 2x/wk (which I will be adding more this next week. I just heard about dosing K to 20ppm. I will be getting some NuSalt hopefully for this, since what I'm using now will kill my wallet! How does my fertilizer regime sound so far? I have never had a planted tank until about 1 month ago, and started dosing ferts last weekend. (I was letting the plants settle).

I also will be picking up some Greenlight stump remover (although my N levels are fine now [5-10ppm], they may later get low). I'll also get some Fleet enema. My PO4 level is about 0.1ppm right now, and I'm thinking of keeping that between .2 to .5ppm.....sound right?

Any input would be great!
