That made it more clear. Thank you Chelsey. I'll look for that product tomorrow at the LFS. What are the readings of alk and Ca that I should be shooting for?

kh anywhere between 2.5-4 or 7-10, depending on which scale you are using
ca, between 350-450

If you can find Dowflake or Pelaflake, that is your cheapest bet for Ca. Many have used Prestone driveway heat and had great results. I was dosing the liquid, but had to dose so much that it got easier for me to start dosing three heaping tablespoons of Dowflake every other day (dry, mixed with RO at the time of dosing) and three heaping tablespoons of baking soda every three days or so (uncooked-dry, but mixed in RO just prior to dosing). This was in a well stocked SPS tank (125), though. I think that should have been too much, but the test kits were tellinh me I needed it. My magnesium was likely off (it seems to help the balance stay stable). One thing you don't want to do is drastically overdose and bring the values up quickly, so start slowly and bring it up over a couple of days. Then monitor frequently until you get the right amount and frequency figured out.

gary, my tank is so small that i think liquid might be a better idea. i'm not sure yet, because i just dosed few drops tonight. i'll test tomorrow to see how much it has went up.

i tested the alk with salifert alk test kit, and this is what i got.
14.4 dKH, 5.14 meq/L

i'm guessing i need to lower my alk now? this is only after dosing baking soda twice over a period of 24 hours interval.

i'll need to test the ca tomorrow.

should i be adding the kent dKH buffer along with the baking soda? i haven't ever since trying the baking soda.

anthony, is 5.14 meq/L dangerously high and i should be thinking about ways to lower it?

i'm still not sure why some of the sps were bleaching if my alk was high to begin with. you think it's the calcium issue then?

Just tested the Ca. it seems to have gone up from 280 to 300. I'll dose with liquid calcium again tomorrow afternoon.

I just add the liquid calcium and the baking soda, never any kind of buffers or anything. Keep testing, you're on the right track :)

Hmm...I don't know what to tell you about your alk...how much were you dosing at a time?

I dose Epsom salt to control Magnesium ($1.94 at Walmart).

i dosed 1tsp dissolved in about 3 cups of water over a period of 24 hours. i should have waited 48 hours. =\

the sps that has bleached so far, do they have a chance of bouncing back? or should i be considering fragging away the healthy parts for now

Bleached as in lost their color some or have they turned completely white? Definately dose in small amounts and wait 24 hours before adding any more.

i'm scared to mess with baking soda for now. i'll test them again in 2 or 3 days. for now, i'll work on getting the Ca up. hopefully by tonight, it will be upto at least 320 or more. i've dosed about 5 drops over a period of 24 hours.

bleached as in, completely white starting from the base, and some parts losing color. only two things has bleached so far. one tricolor acro which has bleached from the base and shows white discoloration in various spots, and my superman monti which began to lose color from the edge.

i would do a water change, your alk is high, but if you raise your ca, it will come down on it's own

i just did a water change about 2 days ago, so i want to avoid doing one. it's such a small tank, and last time i did series of water changes resulted in a near-crash. =\ i'll try to raise the ca slowly over a period of 5 or 7 days.
