Here's what I do for a 1.3g with 13w PC light...
KH2PO4 - 1/8 tsp (.125 tsp) of KH2PO4 mixed into 500ml of RO water.
I dose 5 ml into my 1.3g to get about .9ppm Phosphate level.
KNO3 - 1/2 tsp (.5 tsp) of KNO3 mixed into 500ml of RO water.
I dose 5ml into my 1.3 to get about 3.8ppm Nitrate level.
Micronutrients - 1 tBsp (TABLEspoon) of CSM+B mixed into 500ml of RO water. This is a full strength dosage solution that I use on my 55g. Because of this I dose a very small amount.
I dose 1 medicine dropper drop into my 1.3 (I counted how many drops in 5ml to determine that dosage).
Excel - I dose 3 drops every day.
I do a water change weekly on the same schedule as my other tanks.
M - KH2PO4, KNO3, Excel
T- Micronutrients, Excel
W - KH2PO4, KNO3, Excel
Th - Micronutrients, Excel
F - KH2PO4, KNO3, Excel
S - Micronutrients, Excel
Su - Water change. No dosing.
Filtered with a nano HOB filter. Floss changed weekly. Have a small square of floss that always stays so I don't wipe out my bacteria colony.
