You first need to know what the other levels are, like ALK
. First thing you should do to increase your ph
is increase circulation and surface agitaion. It is likely an increase on CO2
that cas your PH
depressed. Another thing is...when are you testing your ph
? Lights on or lights off?
Here are a couple recipies for ALK
buffers compliments of Boomer (from another board)
Preheat oven for 400F. Cover baking sheet with aluminum foil. Cover foil with baking soda (don't use all of it), spread the baking soda around, since it must have contact with the air. Bake at 400F for 1 hour, or until lumpy and awful tasting (a lot of my other recipes turn out this way). Mix 1 part of baked baking soda with 5 parts regular baking soda (some people use 6 parts regular baking soda). Store in a dry container.
Be sure clumps are broken and mixture is well mixed before adding this to the aquarium, be sure everything dissolves (baking soda dissolves much easier than baked backing soda). Also, be sure to test pH and Alk
6 parts Arm & Hammer Baking Soda and 1 part Arm & Hammer Washing soda. Mix well and add one table spoon of the mix to RO, RO/DI or Distilled water per 25 gal of tank water to raise DKH 1.0. Again always check pH and Alk.
