Water Characteristics
Water Characteristics
  My Value Tap Water Ideal * Comments
pH 7.6 - 8.0 7.6 - 8.0 6.5 - 8.0   <7 = acid 7=Neutral >7 = alkaline
Can be lowered with filtering water through peat and adding bogwood
KH 15 15
50.2 - 57** 		4 - 13 If the KH is too high you can filter the water through peat.
When the KH is low (4.5) this can result in swings in the pH value resulting in fish and plant problems.
KH can be increased with bubblers (drives off C0 2 ) or lowered with C0 2
GH >6 >16
15.6 - 17.6** 		6 - 16 Plants will also grow better with a lower GH.
NO 2 (Nitrite) 0 0 1 Best less than 1
NO 3 (Nitrate) 10-25 10-25 <100 Unfortunately algae problems can occur at levels above 25ppm

* This is an average range since different sources quote different values.
** I am on the border of two water areas. The two reading represent the published water authority values.

0 to 4 dH Very Soft
4 to 8 dH Soft

This is a heard water area, but my tanks is 6-10 dH
