AquaErase — Cyanobacteria & Red Slime Treatment
$26.99
Treats up to 1,500 gallons — under 2¢ a gallon.
Safe for all fish, corals and invertebrates · pH neutral · Results in 48–72 hours · Dosing scoop included
AquaErase is a cyanobacteria treatment that clears red slime from aquarium surfaces in 48–72 hours, in both freshwater and saltwater home aquariums.
It is safe for all fish, corals and invertebrates, preserves the beneficial bacteria colonies your biological filter depends on, and won't shift your pH or water hardness.
One 10 g pouch treats up to 1,500 gallons — around 30 full treatments of a 50-gallon aquarium, with a precise dosing scoop included.
Warning: For aquarium use only. Not for human consumption. Keep out of reach of children. Store in a cool, dry place.
How to use AquaErase
The full directions, exactly as printed on the pouch. Two of them matter more than the rest — read them before you dose.
- Increase airflow to maintain high oxygen levels.
- Turn off UV sterilizers and ozonizers, then remove activated carbon and chemical filtration.
- Keep all pumps and powerheads running for even distribution.
- Dissolve 1 scoop of AquaErase per 10 gallons of aquarium water, then pour into the aquarium's high-flow area.
- Allow the treatment to work for 48 hours, or 72 hours for severe infestations.
- Perform a 20% water change.
- Turn equipment back on, then replace filtration.
Why steps 1 and 2 matter. As cyanobacteria die off they consume oxygen, so extra aeration keeps your fish and corals comfortable. Activated carbon will absorb the treatment before it can work — take it out first, and put it back at step 7.
FAQs
What is cyanobacteria?
Cyanobacteria isn't algae — it's a bacterium that spreads as a slimy sheet across substrate, rock and glass, usually deep red or maroon in saltwater and blue-green in freshwater. It peels off in mats rather than scrubbing away.
How fast does it work?
Visible cyanobacteria typically clears within 48 hours. Allow 72 hours for a severe infestation. Follow the full course either way, then do the 20% water change at step 6.
Is it safe for my fish and corals?
Yes. AquaErase is safe for all fish, corals and invertebrates, and it preserves the beneficial bacteria colonies your biological filter depends on. The one thing to get right is aeration — dying cyanobacteria consume oxygen, so increase airflow before you dose.
Why do I have to remove carbon?
Carbon and other chemical filtration media will absorb the treatment before it can reach the bacteria — leaving it in is the single most common reason a treatment appears not to work. Take it out at step 2, and put it back at step 7.
Freshwater or saltwater?
Both. The same pouch and the same 1 scoop per 10 gallons dose works in freshwater and saltwater home aquariums.
Will it change my water chemistry?
No. AquaErase is pH neutral and won't affect water hardness. Your parameters should stay where they were.
