RAIN2 ATS Installation Results
Going to try posting pics and test results as the RAIN2 builds up the algae layer. I've also sent off an ICP test and I'll do another in a month or two to see if any changes from the ATS - supposedly it also removes heavy metals (not sure I have any but I'll find out with today's ICP).
I have done no water changes since the above 'before' pictures. I did siphon my algae into a filter sock in my sump, but didn't change out any water. I don't plan on it, unless something comes back from ICP that warrants a water change.
Edit 061821 - received ICP results from 06/12. No significant issues noted except my interpreting reading from CA (I'll add ICP to results below)*.
Current tanks parameters:
NO3 - Nyos - 3 ppm
PO4 - Nyos - .025 ppm
Alkalinity - Hanna - 7.2 dkh - a bit low - I usually manage to 8 to 9, I'll add 10 ml today.
Salinity - Refractometer - Calibrated - 35 ppm
Temp - Apex - 80.5 (Checked with handheld)
I don't test for Ca or Mg that often. I only have softies and no coraline to speak of. From day 1 it's been 480 Ca and 1480 Mg. I use HW Marine Reef salt so suspect my high Ca / Mg with is from that and no consumption. If anyone really wants me to test, let me know. Otherwise I'll wait for ICP return.
Ok so I read that and thought..man, what a lazy reefer, the test kits are right here at your feet. So...
Ca - Red Sea - 480, ICP - 437 ppm*
Mg - AF - 1500, ICP - 1318 ppm*
No surprises...but now I feel better.
I'll post pics of the ATS screen here and edit to post going forward for the next couple of weeks. I probably won't post everyday. You'll see some on the screen now. I took some GHA and rubbed it into the screen...most of it washed off but some actually got pumped onto from my cleaning.

061621 - Looking thicker along top. I expected growth to start in middle - suppose it doesn't matter.
061921 - Week update.
Current tank test results (also see post below on ICP):
Temp 77.8 - Apex
pH 8.03 - Apex
Alk - 8.3 - Hanna
Salinity - 35.0 ppt - Refract
NO3 - 3 - Nyos
PO4 - .025 - Nyos
Ca - 450 ppm - Red Sea (correct per ICP)
Mg - 1350 ppm - Red Sea (corrected per ICP)
Observations: I cleaned out the remaining algae in the tank today. I didn't get it all initially (removed 75%) because removing the skimmer I didn't want to have any spikes in nutrients. Obviously it wasn't a concern and the tank is fine. The algae in DT doesn't appear to be growing as aggressively and it looked somewhat less healthy and was much easier to remove (similar to how it acts after a Phosphate RX dose). Granted that could be confirmation bias, but hey it's a positive result and I'm taking it. No parades yet, but I'm hopeful.
062421
Thicker still. Turned off one set of lights on 6/22 after reading
Algae Scrubber Reactor forum in hopes to get that middle filled in. I'll post there in a week if this work for some specific advice. Also added 4 fish (see post) which should increase my nutrients a bit.
062721
NO3 - 3 ppm, PO4 - .025 ppm, Alk - 8.8, Salinity 34.5, pH 7.98, Temp 79.2

Santa Monica recommended cleaning and staying with one light and monitoring for a week to see if screen can get better coverage.
Before
After - removed maybe tablespoon of algae - I'll post in a week.
070221 - No pics, just a quick 3 week update.
Cleaned out the tank for the first time in 3 weeks. Before the ATS - the rock and sand would've been covered in algae at this point. I purposely waited a few weeks to see if things were improving. So the rock I initially cleaned on the 11th is still free of algae. I didn't clean it all then as I've stated. The remaining algae is for the most part browning up on the rock and not spreading. There is a few problem areas still - mostly on my little rock up front with the GSP. Sand bed had a little algae but easily vacuumed up. I would say I removed in total less than I did when I cleaned the RAIN2 a few days ago. So far so good.
070321 - NO3 5, PO4 .025, CA 470, Mg 1470, Sal 35, Alk 8.5
3 weeks without a skimmer and no significant changes. NO3 a tad higher, but using a fresh test kit. Pic of my tank post minor cleaning yesterday. Still no water change, I cleaned to sock in sump and not external bucket.
070621 - One week after first cleaning - spreading nicely.
071021 - Test Results - NO3 - 5, PO4 - .025, Alk - 8.4
071321 - 2 weeks after first cleaning...figure it's about 50% coverage. Been 4 1/2 weeks since installed the ATS. Still very pleased. Algae has not returned to rocks I removed it from before install. Do have some on the sand bed I'll need to clean in the next day or two, minor but don't want it to spread.
More later
071821 - Test Results N - 5, P - 0, Alk - 8.0, Ca - 480, Mg - 1500, Sal - 35, ph - 7.87 , Temp - 80.8
PO4 is now 0 with no detectable to my eyes. Not overly concerned due to continued expanding coverage of my screen and I still have 5 ppm NO3.
I cleaned the screen after the pic above - maybe a tablespoon of algae. I reversed when reinstalled to get coverage on other side - which worked. Probably 75% coverage now.
Interesting observation - I have coralline algae growing on my pumps. I've never had that before, not sure why an ATS would help coralline grow. My nutrients have always been low, Mg/Ca always high. Nothing else is different.
101421 - N/P 1/0 Alk 7.9 C 490 Mg 1380 pH 8.1 Temp 77.6 S 35
The screen isn't much different...maybe fuller coverage of slime and bit less algae. That's likely because I let the DT grow a bit of algae. It was enough that I was getting ready for normal cleaning as I've done every week or two (not as bad as above), but then I noticed that the algae was leaving the rocks and sand. Even the hard to get/never removed areas. All the GHA was on the back panel. So I decided to let it go for a while and see if it kept up. After a couple weeks I basically had no GHA on the rock work or the sand. But I am extremely happy with how my tank looks...better than it has since before dino outbreak.
Will be sending in ICP test Monday (if not today). 4 months without a water change or skimmer, just ATS and 3 tbsp GAC every few weeks.

One of the tabs broke and I used tie wrap (like a good reefer) to hold in place. Actually I like the tie wrap through the screen better. Maybe not as slick as having tabs, but seems a lot more long lasting and easier to manage.
121221 - I know I had an update in here from November - must have deleted it accidentally. I'll recreate the pics at least above. Wasn't much to report as the tank has been stable as can be for the last several months.
I decided to wait until the 6 month point to send in the ICP (that's today). I'll take a set of tests and post that here.
As you can see below the screen has adjusted to lower feeding volume (less fish). Bringing down lighting to darken it up some but it's still pulling nutrients out. There's almost no algae in my tank. I did have a few tufts last weekend (after a month or more) and they simply pulled out with barely a tug just like everyone says it should and rarely has for me. The sand bed is staying clean as well and I've been neglecting my sand bed in only doing a stir once a week maybe. I simply couldn't be happier with this methodology. I'll wait for the ICP results but I'm not expecting any huge surprises. At that point, I'll post the results here and close out this tracking post and put together a summary post - maybe in the main forum - we'll see.
020822 - Test Complete of ATS
I'll be putting a summary post at the end of my thread on the ATS and the testing results now that I have the latest ICP back. I'll post that as well.
Tank and ATS have looked the same now for months (since last pic). Corals a bit bigger perhaps. The ATS never greened up again fully and I have the lights now dialed back to 12 hours/day (overnight) to see if it can green up some without impacting nutrients.
All in all the ATS was very successful in fighting GHA in my display tank and it maintained nutrient levels as well as the skimmer. Definitely worth the money and in a similar circumstance would do it again.
Would I run a tank just on ATS/UV in the future? Yes, no doubt. Will I? It depends. My final thoughts will be in a separate summary - next page.
