Rotalabutterfly.com has lots of info to get you pointed in the right direction.

Also try https://www.advancedplantedtank.com/fertilisers-how-to.html

There is a lot of variables to fertilizing a tank. Read as much as you can on every aspect of fertilizers, co2 ,lights, plants, soils, filtration/circulation, and lots and lots on algae.

It's very rewarding having a planted tank, it's even more rewarding to learn and understand what your tank is telling you. You got this.

250ml bottle for micro
CSM+B 2g / each 2ml dose = .13ppm Fe

250ml bottle for macro
KNO3 6g / each 4ml dose = 7.35ppm NO3
KH2PO4 1g / each 4ml dose = 1.39ppm PO4
K2SO4 2g / each 4ml dose = 1.79ppm K
MgSO4 3g / each 4ml dose = .59ppm Mg
CaSO4 5g / each 4ml dose = 2.32ppm Ca

Add CaSO4 last in macro bottle after everything else dissolves.
Shake this 250ml container before drawing a 4ml dose since most of the CaSO4 will be in suspension in the solution.
It will dissolve once in the tank.

Please check these on an online calculator I ran the numbers rather quick.

You have also not described a target for KH and GH levels in your tank.
I'd recommend a KH of @ least 1dKH

KH of 1 would be fine.
GH of 4 or 5 would also work.


The Ca & Mg in the macro mix could get you by maybe.
That is why I included them.

Worst case you could use baking soda to get a KH of 1
240mg to 8 liters to get a 1dKH
Could maybe add every third water change.

8 liter tank correct???

Yes,8 liter tank
-RO water 100% new 30ppm Ca, 10ppm Mg is 4-5 GH
-RO water replacement 50% more 15ppm Ca, 5ppm Mg
-maintain 4-5 GH a week?

Sounds reasonable.

If you do add Ca & Mg to macro mix it will add a bit more GH.
Or omit the Ca & Mg from macro mix.
