I checked my chemicals in the water and I ran across a problem and need some explanation. I dont remember the exactly but i can guess close. Here are my aquarium info.

Ive been having the tank for about 2-3 months. but i just now started using the test strip just to see if i had any problems. I have never had any fish die on me. But the ph and the alkalinity are both high.

10g Tank
Penguin bio-wheel 150
Marineland water heater
4 Platy's and 3 neon fish
gravel
many many live plants. (java ferns, anubias nanas, lots of water sprite)

Nitrate - 0.5
Nitrite - 0
Hardness - 50 ppm
Alkaline - HIGH i dont know the value but i just know the yellow test strip turned blue.
pH - also high i think 8.5

ANY SUGGESTIONS?
