D-Solv

I missed this before.
That's got to be a heck of a climate change from Cold Lake to Newmarket.

Man, not this year. Looks like Alberta is downright balmy compared to the beating we've been taking here.

Regarding the D-Solv, if it's sodium percarbonate and that is a method of adding hydrogen peroxide in the pond, then there is a danger if too much is added.
I use liquid hydrogen peroxide in my freshwater aquarium to control outbreaks of cyanobacteria and you have to watch the dose because too much could definitely harm your fish. You could wind up burning the gills of your fish or causing gas bubble disease.
I saw the reference to hydrogen peroxide in the Koiphen link jw posted.
Something to be aware of, anyway.

I'm not a chemistry guy...where's Charles?.....

Used my Green Clean this morning. The 5' deep pond had a lot of string algae but I thought the bottom was pretty clean. NOT. Within 5 minutes lots of leaves and gunk floated to the surface. I treated the other pond that has a lot of water lily pots that had leaves etc around them and same thing. Everything floats to the top to be skimmed off. I only use at 1/2 strength as a precaution. I'm sure the filters will need a good cleaning tomorrow but I didn't have to stir up the bottom and spook the fish.
Morewater- thanks for starting this thread!

3% hydrogen peroxide - the cheap stuff in the brown bottle from the drug store? While it may be an issue in the relatively small sized aquarium, I think you'd be hard pressed to put enough in a pond (unless we're talking tiny pond) to cause any problems. I've heard of people using as much as 10 or 11 quarts per 1000 gallons of water. In my 4000 gallon system that would be 40 quarts - I'm too lazy to open that many bottles! (You can buy full strength hydrogen peroxide which is 35%, so that would only be a gallon - not as impossible as it sounds.) I generally add a half gallon of 3% every two weeks or so.

Anyway, everyone really has to do what they feel comfortable with. I brush my teeth and rinse my mouth with peroxide twice a day on my dentist's recommendation with no ill effect so I feel confident using it in my pond in either liquid or granular form.
