CO2 testing and cycling for fish
Planted and filled my 20 gallon tank on Wednesday. Filled with DI and added RO Right to bring back some elements. Did 2 water changes of about 30%. Last night I added some Lilve Nitrifying Bacteria to help speed up the cycling process for fish.
I have Co2 set for 2 bubbles per second for first few days. Now set at 1 bubble per second. Plant list below.
I have an led light above tank with 24 bulbs. Sits approx. 3 inches from top of water. There is a glass piece that sits on top of tank.
Dwarf Hairgrass (Eleocharis)
Micro Sword Narrow Leaf (Liaeopsis)
Dwarf Baby Leaf (Hemianthus Callitrichoides)
Question, is there a way to test the Co2 content in tank to make sure not too little or too much or do you just need to sit and wait to see how the plants look/react? Also, This morning readings on the water show no Nitrite with 20mg/L of nitrate levels, ph of approx. 6.8, KH around 80 and GH arouind 50. Am I good to go with small quantity of fish or could these readings just be inaccurate, since I just started the process 4 days ago.
