Walmart only has the dip strip type test kits..those are complete junk. You want the liquid type.
They mean 100% changes on a 10 gallon..because you said you didn't pre-cycle it.
If you don't cycle it before adding the fish (fishless cycle) then if you don't do 100% water changes your girls will go through a cycle..which can kill them..and/or shorten an alreay short life span.
Cycling is hard on fish.
Changing the water 100% keeps the tank from cycling..as instead of using old water to live in..you take out the old and replace it with new. If you're tank isn't cycled..I suggest a 100% water change at least every 2 weeks, with sooner being better.
I think you need to quit blaming your miscomings and memory on your ADD...my 9 yr old is ADD and has a better memory then I do. ADD does not affect your memory..it just makes you not finish things you start due to lack of attention span, that has nothing to do with your memory.
This thread hasn't left the front page all week...there is no way you forgot it..all you had to do was look.
If you can't remember these things, how are you going to take care of these fish? Are you going to forget about them too, like your "homework"?
I suggest writing yourself notes and taping them in clearly seen areas if your memory is that bad.
