Water Gardening: my pond, 1 by silverfluter

I do beleive the formula is... for irregular shaped ponds, take the longest length, X widest point X depth, to get cubic feet, then multiply that number times 5.7. That should get you in the ballpark. Using that formula out pond holds 218 gallons. I figured it has closer to 180 by timing the amount of time it took the water hose to fill a one gallon milk jug. Then using the total time it took to fill the pond to calculate the total gallons in the pond. Both methods have plenty of room for error, but they get you in the ballpark. The think with the peroxide is, there is plenty of room for error built in to the dosage.
Just how bad is your problem? I posted a pic showing some of the growth in our pond. This was after one application of a pint of peroxide. The lower left corner shows a lot of residual algae on the lilly stems and even on the white plant marker stake. When the sun gets a bit higher I will take another pic of the same area for comparison. As you can also see, our problem was only with the string algae, no floating algae. Stay tuned... Tom
