Hi,

The only thing I can think of is you are stirring the gravel with the cleaner? Move very slowly when repositioning it and plunge it straight down into the gravel and withdraw it straight up and stop the water drain just after removing it.

The amount of ick will go down with each cleaning so it should become less and less of a risk.

Does your tank have support spars across the top anywhere?

I used to use a watering can amd slowly pour the replacement water across the spars to prevent it jetting down into the water if that helps.
