My tank's dimensions are 46"x17"x14" LxWxH
My measurements are from the inside of the glass, so I am not including the thickness of the glass. Also, the height is measured from the top of the substrate to where the surface of the water is. This results in a volume of 47g
When making my macro and micro doses, I calculate for a volume of 45g.
For the past two weeks, I have been dry dosing my macros
Macros 3x a week: Sun Tue Th
1/2 tsp KNO3
6 ppm of K
9.4 ppm of NO3
1/8 tsp KH2PO4
1.2 ppm of K
2.9 ppm of PO4
Micros 3x a week: Sat Mon Wed
Using 1/2 tsp of CSM +B solution in a 500ml container and dosing 30ml per dose provides .05ppm of iron.
I also dose 5 ml of flourish iron three times a week
Total iron dosed during micro days is 1.05 ppm if my calculations are correct using zorfox's calculator.
I have also been adding 4 3/4 tsp of Nilocs GH booster after water change on Saturdays.
According to zorfox's calculator this should provide,
10ppm of Ca
20ppm of K
2ppm of Mg
Nothing is being done on Fridays.
The tank has been setup for more than a year.
I am using one 48" Dutch style BML light fixture suspended. The distance from the substrate to the light is 21"
And the fixture is set at 100% power.
The tank has two 2217 Eheim filters and using pressurized CO2.
The co2 is set to turn on if the water's pH is > 6.1 (using a Milwaukee Ph controller)
Well, most plants seem to be doing well with the exception of my rotalas and some ludwigia (I think)
Here some pictures that could help identifying the deficiency or toxicity.
