ICP Test Seawater Pro Laboratory Analysis with Osmosis Water Analysis for Seawater Aquariums incl. Free Return Shipping

ATI > Triton > ICPAnalysis.com I've tried the three major providers and this is the best. here's why. 1) shipping label included. I'm lazy, dealing with postage in 2019 is archaic. They solve that problem for me ahead of time. Which makes me more likely to actually do the test. Which keeps my pets alive. my precious, precious cnidarians! and their Osteichthyes (fish), Crustacean (shrmps & crabs), and Gastropoda (snails) friends happy. 2) tests RO water. Yep, I found a problem. Neither Triton nor ICPAnalysis.com do this (unless you want to burn an extra test kit) 3) Accuracy. They're Germans. With a lab. Seriously. 4) Nitrate results. the others test for individual elements. I called an insider and they said that ATI spent a bunch of extra money on a special machine to test nitrates but then he got into chemistry which is hard so I got lot. I don't try my Red Sea nitrate test kit, I trust germans with a high end scientific instrument. Yes, my nitrates are too high darn it! The only bad thing is the wait. Yep, it ships to Germany. Don't worry, it's on a plane. And I like the sweet anticipation of RESULTS. It's something to look forward to... and be slightly afraid of. It's like going to the doctor and getting a blood test. AM I NORMAL?!! I can't wait to find out! (and no, even advance reefers don't get perfect results and aren't normal all the time). As far as cost... it's basically like a Star Trek level test on the elemental composition of your water. It involves plasma. and German lab techs. If you are on a tight budget, please go fish only with live rock (there are awesome non reef safe fish I would LOVE to keep. like puffers. especially puffers) or go freshwater. Saltwater Reefs aren't for the light of wallet. Reefers know that reefkeeping is basically saltwater water keeping with some expensive animals on the side. This is the best way to keep your water as dialed in as possible.

Very accurate and they gave me some great advice

I tried the Fauna Marin icp test a few months ago, and not only did they lose my kit, their customer service was non-existent and ghosted me when I inquired about it. ATI's test kit in contrast contained clear instructions, and even an included return shipping label. Using the web site was really straight forward and I had my results within a week (sent from Los Angeles). At $45 this is pretty reasonable too. Very happy with the experience.

I have used several of these to check the water parameters in my reef tank. Turn around time of water analysis is good and they give good recommendations on how to correct any problems.

This ATI ICP-OES test kit is surprisingly affordable compared to other ICP options, and now I understand why my corals were dying — some critical trace elements were way off, and I had no idea. The results were detailed and easy to understand, with recommendations on how to fix the imbalances. It’s not instant (you have to send in your sample and wait for results), but totally worth it. This kit probably saved my tank. If you’ve tried everything and still can’t figure out what’s wrong, get one of these.

Long turnaround time, but solid test results. Love that it tests my Rodi water. Found high silicone in my rodi water who would have known.

DEFINITELY NOT 1–3 day fast service. I’ve taken this test three times, and it always takes about A WEEK for the sample to be delivered to the lab and another SEVEN DAYS to receive the results. By the time you get the results, they’re no longer useful for those who need them ASAP…

Good accurate test, but expect 2 weeks for results. It doesn't tell you that you ship sample to California and they ship it to Germany to be tested. Not worth the money to me.
