I need to now what lvl of makro and mikro do you have.
I have planted tank with a LOT of plants and i give to fresh water when i change them 15 ppm K, 5 ppm Mg , 0,5 ppm Po4, 15 ppm NO3 , and mikro I add daily in size 4 ml ant taht is 28ml in week(0,1ppm Fe in week, 0,1/7 ppm fe daily) and what is not as should be.
for example if i add 15 ppm k to fresh water i want to reach 15 ppm of K in water kolumn.I czange 30% of water every week. if the plants eat all K and before changing water K is 0 ppm when i add 15 ppm to 1/3 water(fresh) i reach aproximeatly 5 ppm K in water column. Good i thiink ?
ok now my problem.More plants semms to be in good condition but some no.
For example hatarantara have black colour in underside of leavs and the black colour push through the top of leavs in all the leaves without 2 maybe 4 new.Is that possible the Mg is to low????
The conus(taper,bell) of indica, aromatica,and stellata are dying and i dont now that is too low mikro or too high?? I add 0,1 ppm fee weekly but i add daily this mikro in size 0,1/7 ppm. My tank now http://republika.pl/andkoni/akwarium6.jpg
