Would depend on how many fish are in what size tank, and how much food is entering the tank daily.
In larger tank, with fewer fish, and careful feeding's then maybe not.
In over crowded,smaller tank's,with numerous feeding's then testing could reveal much about how fast waste is being processesd or not.
If you can skip a day without water change, and ammonia/nitrites don't rise, then this is good sign assuming fishes are present ,and not too numerous for particular volume of water. Is also a sign that biological filter is working as it should. IMHO

interesting. my tank is 20g and 4 weeks old, with 4 platys. in wanting to keep the water good ive been doing 25-50% changes daily. i had 3 platys for 3 weeks and added 1 who turned out to be aggressive. i returned her and traded for a calm one. but now two of them are staying at the top with mouths open.not gasping really but open. i assume the waters good or all 4 would be at top. is that correct? any idea whats wrong or what my next move is? feeding limited 2x a day,half of that is fresh vegs

Because the fish are all not exactly the same, they won't all react the same to adverse conditions. You are right - if the water was really bad, they would all be doing it. However, if it's only a little bad, then fish that are less healthy will show symptoms first.

When you are cycling, it's best to not assume things. There is only one way for you to know whether your water is good or not. Have you tested the water lately?

It's best to not overfeed while cycling with fish. The more they eat the harder it is to control the water quality. Twice a day is really too much, unless you are splitting up one feeding into two, but since you are where you are now that's a moot point.

Apology accepted.

It's best to wait a day after doing a water change to test the water. Water conditioners will give you false positives.

Water for platy's needs to be hard ,alkaline pH 7.6 to 8.0 and around 74 to 76 degrees F.
Need test result's for ammonia,nitrites,and nitrAtes.
Test result's are much better than assuming water is ok.
Once the tank has cycled,then testing doesn't need to be done as often unless you suddenly introduce a bunch of fish at one time.
Is good after the tank has cycled, to perform test's each week before a water change .
This will give you an idea as to what the tank is doing with the fish load present with regards to bacteria colony processing the waste from fish and fish food.
Live plant's can be a huge benefit for helping consume those toxins which are harmful to the fishes.

It seems right in that it's screwy - You have to wait a day to test the water after doing a water change.
