GH / KH questions
I just got a GH / KH API test kit and tested my tap H2O, water in my 20L and 29.
Tap GH is 4 degress or 71.6ppm
Tap KH is 2 degrees or 35.8ppm
20L GH is 5 degrees or 89.5ppm
20L KH is 4 degrees or 71.6ppm
29 GH is 5 degrees or 89.5ppm
29 KH is 3 degrees or 53.7ppm
I am getting ready to do a major reset of both tanks due to getting a ton of plant clippings from a local Atlanta aquarist and will be changing 80% of the pea gravel out in the 20L to 80% Flourite / 20% pea gravel. I will be changing out 20% of the gravel / flourite mix in the 29 and adding more flourite to the mix.
- first the obvious, what do these numbers mean?
- second, should I be raising / lowering either the GH or KH to keep tropical fish and live plants (no CO2)?
- thrid, how should I go about raising / lowering the GH or KH?
- fourth, since I will be doing this major reset and water change should I disregard the above tank numbers and retest after the reset and new water addition. (I plan on using some of the old water to keep the fish from completely freaking out) about 10GL from each tank.
If you have need of any other information from me please post or IM and I will get that to you ASAP.
