My rocks are still covered in algae after two applications: any tips?

Is this product safe to use on water features that attract birds?

Sorry don’t know. Ask manufacturer

How much for a 300 hondred gallon pond

Dilute 1 ounce of CrystalClear Algae D-Solv for every 360 gallons in a container of pond water. Pour the solution into the pond in an area with the greatest circulation. You will see the best results using Algae D-Solv in conjunction with vigorous aeration.

I just have a small fountain, how much should I use for 4 gallons?

Guessing teaspoon. A small portio you’d use in a koi pond. Read instruction. Use a small % of that. We have 2 koi ponds 4x16x2 feet and 4 ft wide and 2 feet deep x 22 feet long.
