Healthy PondsAquasphere PRO Biodegradable Pond Treatment, Treats up to 1,000,000 Gallons, Tan

My lake is just at 1m gallons and takes up about an acre of our land. I put one of these in, waited two weeks and put another in just to nuke it as my lake was pretty nasty looking. After the third week, my water looks fantastic, it was black and crystal clear. The bottom started softening up which means the bacteria was eating the biomass that settled to the bottom of the lake. Love the results and will definitely use again.

The underground fed pond of ours is prone to grow a green bed that duck weed likes to grow on. Needing to order another soon at $106.00 for a million Gal. pond est. it's working good so far. I called n we est. the pond to be 900,000 Gals. In northern NC.

This works great. Highly recommended. You will be pleasantly surprised how well it works.

I buy these pond balls twice a year for my million gallon pond. It stays muck free year round and clear. I swim in this pond all summer and don't worry about getting slimy feet when I go in.

Love treating our pond naturally twice a year with this. It keeps our pond healthy with sparkling water!
