Levels

Hey all im having a problem keeping my levels up especialy my dkh and calcium. and my PH is always high. after PWC my PH is high. i test it before i feed and before the light go off and its high.. as for the calcium it dips from 430 - 360 in 1 day. my mag is at 1300 so thats good. my dkh is at 9-11 but if my dhk is good my calcium is wacked. and if my calcium is good my dkh is wacked. i dont understand it. as for my PH its always about 8.4 or higher. nothing helps i did a 30% PWC and it was still high. is their something im doing wrong? and im having a small algae problem and i think its due to the PH.
thanks
Matt

How old are your test kits. I would take a water sample to your LFS and have him double check your results.

I'd also suspect the test kits - that amount of calcium consumption is pretty odd, even with huge coralline algae growth. The other thing that could be happening is that it's just precipitating out of your saltwater. Are you noticing any white dust on your rocks? Precipitation would be caused from an imbalance of your ca/alk. How long has this tank been up? Are you adding any buffer or calcium products? PurpleUp? Also... what brand is the test kit?

I dont have a Phosphate test kit but do you think phosphates could be killing my calcium?

The fact that this is such a new tank, and you're adding both calcium and buffer, leads me to think that you've got your parameters out of whack and your calcium is not staying in solution. At this stage in your tank's life, there's probably not enough coralline growth to really require ca/alk supplementation other than normal weekly water changes.

Based on that thinking, I'd lay off the buffer/ca, wait a couple weeks doing your normal water changes, and then retest things at the end of a couple weeks. Then you'll probably have to follow the advice given in this article...

Chemistry and the Aquarium

... to get your alk/ca back in line.

Not familiar with the tetra kit, but have used the API calcium kit. While I've found it's not the most accurate in the world, it DOES seem to be pretty consistent and get you close enough for what we need it for. So I'm thinking your test kit is OK.

I agree with the suggestions made. Stop all dosing and let your tank settle for another month or so.
