testing input

Well, I have everything but mg. It will be picked up today...for some reason it had to be ordered, everyone locally was out?....anyhow, Here are my most recent results..
no2 = 0
nh3 = 0
ph = 7.8 still
no3 = 20
po4 = 0
ca2 = 460
kh = 196.9

Today is my water change day...but I want my mg reading first...so I will wait untiol I get back from lfs.

Any input would be helpful and very appreciated.
Thanx.

 

Its better to test ph right before the lights turn off. If 7.8 was in the morning, thats pretty normal. My ph in the morning is sometimes at 7.7. Salifert is hard to come by, the rumor is that the guy who owns Salifert is the same guy who makes all of the components and he doesnt let ANYONE else make it and he is sick. All of my LFS are out of Salifert, even DRfoster and smith are back ordered. I found the Mag tester at Marine depot.

 

Im gonna test the mg when I get back from the lfs...then change out my 7 gal. and test again this evening..I remember now...ph in the PM.. : )
BTW..
After the every other week 7 gal. changes, should I give it a day or so to get settled(before testing)...or as in this evening I will be testing approx 6 or 8 hours after water change..
Thanx.
