see if the cleaner sontains ammonia
(ammonia) doesn't hide in the substrate (gravel) or anywhere else for that matter,
it is diffused into the water column upon production.
is primarily produced by fishes body waste and respiration, and the decomposition of organic matter within the tank. Most of the waste organic matter in a tank ends up in/on the substrate and decays there generating NH3
, hence the need to vacumn the substrate in order to remove these NH3
To add my $0.02 to the original question...
I would do a total water change, add a max dose of dechlor, preferably a brand that also binds NH3
into a non-toxic form and add a generous amount of carbon to your filtration for a week, you'll probably recycle but "Better safe than sorry."
Step by step...
Max dose the entire tank with dechlor/NH3
Now siphon out as much water as possible, add just enough water to cover substrate and dose with more dechlor/NH3
remover, stir gravel thoroughly and then top off the tank, now add carbon to filters to remove any leftover chemicals.
That is what I would do.
