Chrysophyta (golden-brown algae)
The Chrysophyta are the golden-brown algae and diatoms, which respectively account for 1,100 and 40,000-100,000 species of unicellular algae. These algae occur in both marine and fresh waters, although most species are marine. The cell walls of golden-brown algae and diatoms are made of cellulose and pectic materials, a type of hemicellulose. In the diatoms especially, the cell wall is heavily impregnated with silica and is therefore quite rigid and resistant to decay. These algae store energy as a carbohydrate called leucosin, and also in oil droplets. The golden-brown algae achieve locomotion using one to two flagellae. The photosynthetic pigments of these algae are chlorophylls a and c, and the accessory pigments are carotenoids and xanthophylls, including a specialized pigment known as fucoxanthin.

The Beginning...
JBJ Rimless 30 gallon. The tank was erected on Feb 1st 2016. The two photos above are March 1st 2016.
Diatoms, CUC, Coral
Not long into March did diatoms bloom. Additional clean up crew was added. 3 Cerith, 3 Astrea, 2 Nassarius, 2 Turbos. A few days later I added 3 coral. 2 types of zoanthid and 1 acan.
Let's fast forward a month and discuss inhabitants.
This tank was started with the "BRS method" or dry rock and bottle bacteria. Everything was planned and executed properly. The first 3 days after the tank was started and bacteria added, ammonia, nitrite and nitrate tests were preformed. All tests were good with no detection of ammonia or nitrates. As suggested by BRS a fish was added. I chose an Azure Damsel that had been observed for more than 4 weeks at a local fish store. The fish was healthy and active. He remained in this tank for exactly 28 days. Ammonia, nitrite and nitrate never spiked.
First month:
Azure Damsel
The Damsel was returned and I immediately added my existing live stock from my previous tank. At this time 2 clownfish were introduced. A month later a Firefish was introduced. Following was my pistol shrimp and goby pair. Last but not least, the cleaner shrimp was added. This took a total of 3 months to get that list moved over.
Four Months Later:
Azure Damsel(removed)
Clownfish x2
Firefish
Hi-fin Goby
Pistol Shrimp
Fifth Month:
Firefish was found dead inside shrimp and goby cave. It was believed the firefish had a hard time establishing itself a home. Often times darting itself quickly into the shrimp and goby cave. This accident was witnessed more than once, even though the firefish had it's own cave. I believe the shrimp got the best of him out of being frightened. After 3 days of no signs of firefish, a large rock was removed to find the skeleton and partial face of the firefish.
A week later Phosphates spiked and 2 turbos died. not sure if it was related or lack of food for turbos. 2 weeks after that phosphates peaked at 0.21ppm. Cyano quickly exposed itself.
Identification Period via R2R
The mulm, sludge, slime, slop, whatever you want to call it began to progress. I decided to get on R2R to get a positive ID and go from there. Diatoms, Calothrix, Dino, Cyano, Nutrient mulm and now Chrysophytes have been floating around. Quickly more pictures and videos have been uploaded.
The pictures just weren't telling enough so on to the videos...

Videos weren't enough. On to the microscope!

Things I've tried...
The tank today September 1st
(actually this was taken 14 days ago, not much different though)
Todays water parameters
SG: 1.026
pH: 8.4
Cal: 450
Alk: 8.5 - 8.7dKH
Mag: 1610(bad bucket of TMPR)
PO4: 0.02ppm
NO3: 2ppm
Amo: 0
Nitrite: 0
Temp: Somewhere between 76F and 81F deg. Four thermometers all with different readings.
Finnex heater set at 79 deg.
Last water change was 9 days ago. 10% WC performed at 3 gallons.
Tank peripherals
JBJ RL 30
Aquamaxx HOB-1
Chinese 165w WIFI LED
2x Jebao RW-4 with Aqualink S1 controller
2x Finnex 100w heaters with controllers
Jebao DC3000 return pump w/ controller
Hydor Smart ATO w/ Avast peristaltic pump and reservoir
Dosing
3ml KNO3 'stump remover' once every 3 days
Filtration
Stock media basket
Sponge
Matrix
Skimmer
Conclusion
I need a cure. The tank is 8 months old now. The golden algae is still thriving. I apologize if I missed some information. Please ask me anything.
I want to give thanks to @twilliard , @brandon429 , @Russ265 , @saltyfilmfolks and anyone else that I've forgotten.
