Thanks....took the readings into the local petstore and they confirmed the water was ok. Bought a couple of colourful male guppies and a bronze cory ...... they seem to be adapting quite well. Not sure how much to feed them though....crushed up about a dozen flakes of tropical food and put that in the tank 8pm and 8am.
Congrats on your new setup.
Just a couple of thoughts: with male guppies you are going to need more than two as they are highly sexed macho characters; there is a serious risk of bullying with only 2. A group of 5 or more will spread aggression, so it's not the same poor sod that gets it in the neck all the time.
(If you can handle the fry, the other option is getting 4 or more females- for the same macho oversexed reasons, you need at least 2 females per male, but be warned- they are very prolific fish.)
If you have the room, your cory will also be happier with some mates, as they are schooling fish. At least 2 more, and gender does not matter, as corys are totally unaggressive creatures.
A dozen flakes seems quite a lot for these 3 fish. I calculate about 2-3 flakes per day for my female guppies, maybe a bit less for the males- so about 2 flakes/day. The cory, maybe a bit more, don't know for sure as I feed mine catfish tablets (1/4 tablet per cory once a day). Overfeeding will mess up your water stats.
I also feed my gups veggies (e.g. 1/2 crushed pea or a few shavings of sprout) twice a week, and jellied bloodworm or daphnia once or twice a week.
