Hi all,

What kind of deficiency can it be? I am using Micromix plus, DIY macro, co2, Gh6 Kh2-3, 0,63w/liter T5 light, Hydor600 with full of seachem matrix and TM30 sponge.

Thank you! I will try to give more Gh from salts and less from tap water. Now I am using 70%ro and 30% tap water(without salts) to have some Kh in the tank. Tap water is 22gh 11kh. I'm adding 0,4 ppm fe/week.
Now I gave 30ppm Mg to see what will happen.

Thank you! If I am using only tap water it would be to hard for example blyxa. The co2 also would be a problem.
I have got MgSo4*7H2o, CaCl2*2H2o, CaCo3. I will try to make 6Gh and 3Kh from this.
 
Hi
Blyxa need a tad more phosphate, good lighting plus a soft substrate with reasonable Co2 distribution!
This will make this plant flourish!

Ph kh table. I need to add much more co2.
No!
Lot's of people make that mistake ( and please throw that table away).
The amount of CO2 IS independent of hardness, you can discus the resulting pH is influenced by the hardness, but NOT the amount dissolved.
Allso all the ions in the tank have influence on the pH ( thus making that chart of CO2 vs pH unusable) but not the amount of CO2 dissolved, that is totaly dependent on the way you administer the CO2.

So can I have blyxa, alternanthera reineckii mini in gh22 kh11 with almost the same quantity of co2? That would be great because I don't have to use the Ro system anymore :D
