Some excellent advice on GFY !
The water isn't actually too bad at all today. Gonna give it another few days and judge if it's ready then to add some fishes.
It is only a small tank, and i'm gonna stick to just some nice guppies etc to start out with and see how i go from there.
I did own a huge aquarium years ago, and it was fine for many years. Although we did perhaps mix too many fish haha. They would all act like they got along, then when the light went off at night, Bedlam !!
