Nitrite should be a 0 ppm.
Yip
ur ph is alittle on the high side for alkaline, try buffering it down to a neutral level of 6.8 - 7.2.
I wouldn't bother. A ph of 8.0 is quite common and most fish will adapt to it with no problem. A stable ph is most important, far more so than the actual value.
I use ph down. But make sure you do the ph down in the bucket before you add it to ur tank and lower ur ph level gradually, due to if it fluctuates severly it will harm ur fish.
Please don't use PH Down. As i said, theres really no need to change your PH value and Ph adjusting chemicals such as PH Down will inevitably cause problems. The first time you use it, you are then dependant on it to keep your Ph correct. The first time you forget to add it, you will suffer PH swings which can kill your fish. Much better to leave Ph as it is.
Also what is ur alkalinity (KH) reading, if it is high you will have a hard time keeping the ph level at a nuetral probably due to hard water.
Actually, hard water helps keep the PH stable. If your PH is 8.0, your water is probably reasonably hard. Don't mess with it. You will only cause yourself problems.
What I have done to soften my water is add aquarium salt. 1 tablespoon to each 5 gallons of water, alittle more if needed.
Again, no need, and depending on which fish you have, it may do more harm than good. Most freshwater fish tend not to like salt very much, although some do.
I heard if you put crushed coral in ur filter it will buffer ur water.
Yes it will. It will make the water harder and increase the PH. In your tank, there is no need for this.
Sorry to be so negative about your comments Kaylee, but IMO that was really bad advice.
Those are some funny readings that you have. Fish-in cycles can be that way. Try keeping a log for another week or so. It may be easier to tell by then.
Cheers.
