Frequently Asked Questions

Pond dye vs. phosphate binder vs. beneficial bacteria - what does what?
Pond dye reduces sunlight penetration, limiting algae growth before it starts - it's preventive. Algae Armour is an iron-based phosphate binder that locks up the key nutrient algae feeds on. Beneficial bacteria (Kasco Macro-Zyme, Muck Pucks, AquaSphere PRO, and fast-acting Blast) break down organic matter and muck, reducing the nutrient load that feeds future algae. Most healthy ponds use bacteria routinely, dye seasonally, and a phosphate binder when nutrients climb.
Are these products safe for fish, pets, and wildlife?
The treatments in this collection are natural and biological - pond dye, phosphate binders, and beneficial bacteria - and are safe for fish, pets, waterfowl, and irrigation when used as directed. Always follow the label rates, and if your pond is used for livestock watering, check the product label for any use restrictions.
Should I use treatments instead of aeration?
Treatments and aeration work best together. Aeration addresses the root cause (low oxygen, poor circulation) while treatments handle the symptoms (existing algae, muck, poor clarity). A pond with good aeration needs fewer chemical treatments over time.
How long does shipping take?
Orders ship across Canada from stock. Delivery typically takes 3 to 5 business days depending on your province. Note that some liquid pond dyes cannot ship during freezing temperatures.
