OK. I'm going to start with multiple 10% changes and then reassess in a few days. In the mean time, I will also order a Triton test. I'll post an update in a few days.

What is the corals turning more green an indicator of? We've been having an issue with TN and have noticed 2 of our sps corals green color brightening up (one is a red planet and the other a cali blue tort).

Default Test kits and Salt - Buyer be ware!

Thanks to the advice and encouragement from this forum, I think I may be back on track to a healthy tank. The short answer is be VERY suspicious of your test results and even the salt you buy.

Following advice in this thread, I sent off for a Triton Labs test. Triton results are attached to this post. I believe the most significant result was that my Ca levels were far below what I expected. There was also an indication of high Fe levels, but I doubt that's the problem. I did use PhosBan GFO in my tank years ago when the tank was new, but I can find no current iron/rust sources in my tank.

These Triton results caused me to purchase new Ca and Alk test kits. And of couse, my new Salifert Ca and Alk test results are very different from the API & Hanna results I've been using for years.

new Salifert Ca 350ppm versus API 400ppm
new Salifert Alk 5.76dKH versus Hanna 7.04dKH

After these results, I began a series of10% water changes, 5 changes over 2 weeks. And I began ramping up my Ca dosing and my Alkalinity solution dosing (use Bulk Reef Supplies balling solutions). I was also surprised to find that my newly mixed saltwater made with Reefers Best Salt tests at 5.2dKH and K+360ppm, Ca is ok at 455ppm. So even with the water changes, I've had to increase my sodium carbonate dosing from about 28ml/day to 110ml/day still my Alk is only up to 6.4dKH.

My favia and chalice coral have finally started showing sweeper tentacles at night. And my Sunset Montipora is showing better polyp extension and a bit better coloration.

I know I'm only one in a long list who have been harmed by inaccurate/inconsistent tests and batches of salt. So once again, the problem was right under my nose, but so hard to see.

Thanks for the support.

I also had problems with high Barium in zeo tank like you... When I recieved results from triton my barium was around 300mg/l (it should be 10mg/l) They advised me to use their PO4 remover which also removes barium... As I added it I noticed that corals were happier. One week of using remover and I could see big difference.

I've been having very similar problems with my system.

What does the corals turning green indicate?

Usually high PO4 or a iron or iodine overdosage. I have seen this also if there are some kind of equipment in the system which has rust.
