Here is an image with full light. I will post all the params tomorrow.

Likely spirulina

But ID doesn't matter in algae threads, the action matters

Can we see the sandbed, that's where the catchments are

Depth, pigmentation in the bed, any extra growths and other small details matter in my opinion. Looking great so far! For sure that rock lift out it, clean that off, rinse well in sw, put back. Be the grazer this round
 
I see the telltale whiskers of a lysmata shrimp

Very sensitive, they're our mine canaries for bad water. That's good water you've got/ small clues from the pics. Actions taken need to account for sensitivity with those expensive shrimp.
 
I can see edges of the sandbed on the side of the rock in the full picture

It's got coverage, it has the extra growths and impacted waste possibly unless you've been dedicated cleaning it the whole time. This is classic old tank syndrome


I wrote a work thread on reversing old tank syndrome, by rip cleans of course :)



In this thread the university of Florida I think it was uses rip cleaning to rehab and skip cycle rebuild just after a hurricane loss of power crash. There's several examples of tank handling done our way saving them from loss

Notice the recurring themes:

We don't ID anything

We didn't ask for parameter readings

We never used bottle bac: keeping the cycle intact means we just cleaned the tank, it's not a start over. A start over is a new cycle on new rocks with new corals and fish. By surgically cleaning your tank vs guessing with dosers and test kit levels you skip the risk of giving your tank full blown dinos or an alternation of generations into a gha forest.

Your tank will simply look brand new 24 hours later and you keep all your current sand, rocks corals and fish. We need all new water matching temp and salinity only for the job.

R2r is where my examples are because of the rate of entrants = high but we want to build new work threads here, live time fix jobs. At fifteen years you've got beyond common time and invest into that system. It's 1% on the site to have a nano that old. There's a lot on the line.

Only choose a method that works in others tanks by pattern.

**side warning
Anywhere I make work threads that eventually become logs of tanks worked with outcome tracking, at the start there's haters. I have to endure it lol to get my outbound reef work. It's noise, static in the line, rf multipathing one must deal with. Ignore the trolls

Consider just the actual reefs: what did surgical skip cycle full cleaning all at once do for the tanks, were the owners happy?
 
We could plan the surgical cleaning for your tank here in sections it will seem crazy but that's one of fifteen threads all doing the same thing. One of them is sixty pages long of tanks/9yrs running.

The reason it's so fun is because we're breaking all current laws of reef care and cycle control, while updating the current rules with better ones :)


The results are too bright and shiny to ignore, that's why it's fun. You'll be rinsing for hours/ catch up tank calories time/ but the outcome is already known.

We then keep your current light settings/ no whites, but lower the power just a bit and ramp back slowly over ten days while feeding the newly clean tank nicely. You will get a coral boost; we'd be giving them ultra clean water with no allelopathic compounds in solution, all corals like that. The rip clean removes all the invasion and the waste impaction in the sandbed and rocks: 1st paragraph.

Supplies needed

Totes with lids to contain jumping fish

A substrate rinse bucket

75 cents bottle of peroxide

All new water readied +10 gallons extra for unplanned needs, extra side rinses. This is a tap water job 98%--> you're only getting enough saltwater to fill your tank plus ten gallons so when it's time to refill you don't run short. we start the tank back with all new water in every job

This is an affordable venture for as much return/ it de-ages your tank while preserving coral maturity.
