thank you!red cyano. red slime remover will work like a champ!
hard to tell, but looks like it could be a sponges or tunicates. Can you see in/excurrent siphons or pores?
comes apart.does it stay together in chunks or come apart? if it comes apart, it's probably more cyano
Its a bacteria with characteristics of cyano and can be removed with a turkey baster using suction or siphoned easilyany chance you know what this is?![]()
Looks more brown
will try this thank you.Its a bacteria with characteristics of cyano and can be removed with a turkey baster using suction or siphoned easily
Agree on cyano.
thank you. My nitrates and phosphates have never reached passed 2.5. I assume i am getting cyano because of the low numbers.Agree on cyano.
Cyano blooms typically start when water nutrient 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. 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 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 3-5 days in lieu of resorting to chemicals which at times cause harm. 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 which serves as an oxidizer. Add a pouch of chemipure Elite which will balance phos and nitrate and keep them in check.
After the 5 days, add a few snails such as cerith, margarita, astrea and nassarius plus 6-8 blue leg hermits to take control.
