it looks like cyano. is it slimy?
Cyano can be many different colors: red, green, dark-blue, purple, etc. I wouldn't be surprised if it was cyano that looked odd under your very blue lighting.There’s no bubbles anywhere and Cyano is usually a different color
I’ve had cyano previously (I have had to fight it for 2 years…) and it first emerged under heavy blues. Looks nothing like this, it’s usually a deep red. Cyano bacteria doesn’t appear bright orange even under heavy blues.

It actually looks more like it could be a type of sponge to me.
This is cyano bacteria. Cyano generally is triggered by high nutrients such as elevated nitrate and phosphate and high white light intensity. Like when your body gets too much sugar, the same happens with nutrient levels triggering this.

This is cyano bacteria. Cyano generally is triggered by high nutrients such as elevated nitrate and phosphate and high white light intensity. Like when your body gets too much sugar, the same happens with nutrient levels triggering this.
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. When the protein skimmer does not output the best efficiency or you do not have the suitable protein skimmer to cover the tank, the air bubbles created by the skimmer might be insufficient. And this insufficiency of air bubbles can trigger the cyano to thrive.
- 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.
water is generally the key issue and to determine- Purchase from a different location and see what changes you noticeAppreciate the In depth resolution, the store I receive my RODI from always has 2-8 TDS I had found out myself. Went there and they told me it was reading 3TDS
My protein skimmer is a reef octo 110s so it shouldn’t be an issue. I have 5 small fish and a tang so that’s reaching heavy stocking for a 55g tank in my opinion but I do weekly/biweekly water changes. Ever since I actually did more WC this red slime has appeared more.
I always ran higher nitrates 25-35 with monthly 20% Water changes but now I’m running 10-20 nitrates and biweekly water changes. I do 10-20%
It does blow off if I run a higher flow at that spot , that spot seems to be in the dead spot as I have a circulating flow around the center.
I believe my issue has been the water source I receive from.
I have purchased my own RODI system and I’m awaiting my RODI booster that comes this week. However, I’m in a rental home and I’m closing into a home in 1-2 months. I plan to setup the station there with another tank. Looking at RSR625xl or RSR650 peninsula, considering my issue possibly with silicates or nitrates from the RODI Should I start with entirely new water or use existing and add new water and try and resolve.
Would this big of a water add create a cycle ?
