Dino’s ?

[RC Reefer 5184]

Ok guys. Been fighting this for a while now. Tank is about 18 months old now. I feed Lrs frozen once a day and some nori every other day. First off numbers are
Alk-8.7
CA-475
MG-1280
Ph-8-8.2
Nitrate-.12
Phosphate-.012
Running a uv sterilizer, reactor with carbon a Rowaphos. Water change 20% per month. Running rodi water with zero tds. The stuff blows off easy and is back within a couple days. Any help would be appreciated. Thanks

Maybe and some cyanobacteria

Is the nitrate .12 or 12 ?

.12 Low for sure

Cyano blooms typically start when water nutrient concentrations go haywire. Just like when you eat too much sugar and your waistline starts to bloom, the same happens in your tank when concentrations of phosphate, nitrate and other organic compounds are too high.
Some of the most common causes include:
- Protein skimmer which fills water with tiny air bubbles. As bubbles form from the reaction chamber, dissolved organic compound molecules stick to them. Foam forms at the surface of the water and is then transferred to a collection cup, where it rests as skimmate
- Overstocking / overfeeding, your aquarium with nutrients is often the culprit of a cyano bloom
- Adding live rock that isn’t completely cured which acts like a breeding ground for red slime algae
- If you don’t change your water with enough frequency, you’ll soon have a brightly colored red slime algae bloom. Regular water changes dilute nutrients that feed cyanobacteria and keeps your tank beautifully clear
- Using a water source with nitrates or phosphates is like rolling out the welcome mat for cyano. Tap water is an example
- Inadequate water flow, or movement, is a leading cause of cyano blooms. Slow moving water combined with excess dissolved nutrients is a recipe for pervasive red slime algae development

I recommend to reduce white light intensity or even turn them off for 5-7 days. Add liquid bacteria daily for a week during the day at 1.5ml per 10 gallons. Add Hydrogen peroxide at night at 1ml per 10 gallons. Add a pouch of chemipure Elite which will balance phos and nitrate and keep them in check.

After the week, add a few snails such as cerith, margarita, astrea and nassarius plus 6-8 blue leg hermits to take control.
