I just bought fish tank and put tap water in the 90 litre tank and put the filter on for 24 hours
But I out fish in just now and didn't know about the cycle I'm suppose to do as I wasn't told
What can I do now to prevent my fish from dying of toxic, is there way to get my tank up to date with the right level of healthiness for my fish
Only tap water I put in and it's cold fish... what can I do now, what do I need to buy to help me
