problem maintaining proper parameters
Hi ,
I seem to have a real hard time maintaining proper parameters in my 90 gal reef. (mostly LPS, softies and a few clams) I've been using the reef chemistry calculator to help me out, but it only seems to push my PH down when I add the suggested calcium and buffers (I ues ESV B-ionic two part solutions). my calcium has been in the 350 ppm range and the alk is in the range of 7.7 to 8.5....I've been adding the suggested quantities by the calculator, to bring the paramters where I want them (i.e calcium 400ppm and Alk to 10-11) but it only last for a few hours and then it falls back on the lower side bringing the PH down with it. My magnesium reading are in the 1200-1250 range. I'm also dripping kalk 24/7 (top off water), could that play a role with the unstable parameters and suggested dosing by the reef calculator. I hope to hear your comment ....and suggestion...Thanks Marco

From what I have heard is that if your dripping to much Kalk it has a huge effect on your PH.....what do you mean when you say it brings your ph lower as in closer to 1 or closer to 12????

Dripping Kalk 24/7 is what is influencing your results. You need to carefully control how much Kalk is added in a given time period.
The inexpensive way to do it is to measure the amount into a container, then let it drip such that the container empties before 24 hours. Repeat with the same amount the next 24 hour period. This way, you always know exactly how much you've added over 24 hours. Measure your Ca/Alk so you know if you need to drip more or less Kalk. If you are simply keeping a container full of kalk and letting it drip constantly, you're headed for trouble.

If thats the case then how does a kalk reactor work? Its feeds Kalk when ever the top off turns on. No way to measure how much kalk you are adding to your tank at any one point in time. depending on how hot or cold my house is that day I can use from 1.5 to 2.5g of top off each day. My skimmer as well plays a part in it. Sometimes it removes a fare amount of water other days not a drop. should i be trying to figure how how much it adds per day or have i got it totaly screwed up?
That would suck lol

If you keep your alk between 7 and 9, you need to keep your calcium at at LEAST 425ppm/Ca. This is because if you keep your alk and Ca in balance with each other, you pH should stay the same, or in the very least fluctuate less.
