Quite simply, yes… but you will potentially kill the beneficial bacteria in the Balls. If you are using chemicals to treat your fish, then it is best to wait 7 days and then put a fresh batch of Aqua Balance into the pond.
Can Aqua Balance harm my fish?
The Aqua Balance range is completely harmless to your fish. If they attempt to swallow a ball they will quickly spit it out. Should they swallow one, then it will pass through the digestive tract causing no harm.
How much Aqua Balance do I use?
The dosages are on the tub. Don’t worry if you are not sure of your gallonage as you cannot overdose.
