Why AquaErase?
Safe for aquatic life
Gentle on fish, corals and invertebrates while preserving beneficial bacteria colonies.
Fast-acting
Treats visible cyanobacteria within 48–72 hours. See results quickly.
Freshwater and saltwater
One product for all home aquariums — the same pouch, the same dose.
No water chemistry impact
Maintains stable pH and hardness throughout treatment — no chemical disruption.
Thirty years of service calls behind it
AquaErase was developed by a professional aquarium design, installation and maintenance team with more than 30 years of hands-on experience across freshwater tanks and reef systems.
Red slime is one of the most common problems we get called out for. The treatments available either worked too slowly, stalled the biological filter, or moved water chemistry enough to create a second problem. So we made our own, and used it on client tanks long before we sold a single pouch.
