This is probably a really stupid question, but how do you find out the parameters?
The hardness of the water and the pH are the two important parameters. Temperature is also a parameter, but you already know that and it is fine. Nitrates are also important.
You can buy test kits for both pH and hardness, or a combination kit. Hardness is not something you usually need to test over and over, since once you know the hardness of tap water it is unlikely to change. Some fish stores will test water for you, and getting them to do the hardness test (ask for GH and KH, and get the numbers) will be sufficient.
A pH test kit is not very expensive, and worth having, as pH fluctuations in an aquarium can be dangerous. You should also have a nitrate test kit, as nitrates can increase suddenly if something happens. Once you have plants growing in the tank, nitrate will (should) be low and not a problem.
No question is stupid, don't ever be afraid to ask questions here; we have all learned these things by asking questions, or for the "older" of us
by making mistakes and learning the hard way.
