HELP! cycle an aquarium
I haven’t had time to absorb everything in your post and I don’t want to get into details because one thing I wanted to bring to your attention is that the goldfish should be in at least a 55G… if it’s a fancy goldfish.
Long-bodied goldfish need much more room since they are big swimmers and grow to over 12″ and up to 24″ long. I recommend that they be in a pond.
The 20G is much too small for a goldfish and will cause it to become stunted if left there for too long and stunting causes many stress and health issues usually leading to an early death of the fish.
Now that you may be losing one of your 55G’s, you may have to re-think the rest of your plans…. or re-home the goldfish.
As far as quick cycling your new tanks, if you have 10 fish in one tank and split them into two tanks, take a proportionate amount of filter media from the one tank and split it to the two tanks and you will have minimal cycling issues.
