Randy,

So how do we go about determining the accuracy of our analysis? I understand that seawater complicates things but a reliable standard sure would be helpful to this discussion. As a...

I completely agree, consistency is the key and the best judge is direct results. Now if someone is using the exact same test kit and they open a new bucket and get significantly different results and...

Gee, sorry I covered old territory, guess I didn't read every post. Still, if one doesn't have a reliable standard, they really can't say what test kit error is. I missed the part where the results...

To highlight something from ASI that I quoted in my last post, having a reliable standard is very important. It's not enough to say that one just bought a fresh kit or is using one that everyone says...

For what its worth, here is an exchange I had with Bob Studt of ASI back in the spring of 2005. He provided excellent customer service and I cannot fault anything he said or did. The only issue was...

From a few posts ago...

If I didn't have to add more Ca and Mg to RC too, one could argue that the little extra cost is worth it, but the fact is, since I have to add Ca and Mg to both RC and IO,...

Hope this is not off track, but I have used mostly IO for the last 4 years and I have never tested Ca greater than 350 ppm or Mg greater than 1,250 ppm in that product when mixed to sg = 1.026. It...

I used to use RC and also tried Tropic Marin Pro for quite a while but never saw a benefit in terms of health or behavior of corals. Came back to where I started: plain old IO. I have to add 200 ml...

Yes, better to be safe than sorry, but the ultimate test is what happens in your tank, so add a lot less than you think you need and test. Should be easy enough to test what you made up by diluting...

I suppose you could dilute it and then mulitply the results by the dilution factor. Use RO water so you are not adding anything. For instance, if the alk part is supposed to be 1,900 meq/l and you...

Acro v. Acro

I was just curious, but maybe I did something stupid. I placed an A. formosa next to an A. yongei that had been there a while in a way that would make contact inevitable if one of the A.f. tips...

Just to close the post, our friends at WWM hit the nail on the head. Discoloration was "burn" due to formalin dip. Symptoms are fading and fish looks like it is on its way to full recovery and normal...

Couldn't resist and just introduced a Flame Angel. Mostly picks at rock, but does pick at a couple SPS, one Acropora yongei in particular. Most significant consequence so far is that the A. y. polyps...

Thanks for the comments and the link. In my case, I think that I just did not detect the relatively small change in Ca.

Consuming alkalinity but not calcium?

I started with 3 X 175's over a 170-gal, 24" deep. That was a mistake. Switched to 3 X 250's single ended with T5 actinics and have been very happy. A single 400W on a track would be interesting, but...
