Does Mosquito Bits/Dunks change water quality?

[Donna Saverino MI]

I do not have fish in my pond right now. I had an accident with them. Long story. I completely changed my water 3 months with fresh water. I only have a 62 gal pond

I had to inoculate my pond with "quick kill" Mosquito bits along with the dunks. I did NOT check my water quality before I did the first water test. When I did run tests my phosphate it was very high. The levels of the others, PH , ammonia, nitrite, were OK. Do you think it's from the Dunks? I have to get my water back in shape before I get new fish.

I use the dunks for a bit now. disclaimer i do not test my water i let the pond and fish tell me whats wrong.

I have never had a issue with the dunks and the only reason i use them is for my bog where i have standing moisture other then that i have enough moving water to prevent bug suckers to lay eggs

Not supposed to. There’s nothing harmful in them.

Then wouldn't the other test (Nitrate, Ph, and Ammonia show something going on as well? Like I said there are no fish producing problems.

Unless you're a mosquito trying to have a family!
