Hallo!
I'm not satisfied with the growth of some of my plants.
But first some tech. info..
Filtration: 2xinternal filter (2x600lit-h)
Flow pumps: Atman 2x500lit-h , 1x350lit-h
Overall flow: aprox 2500lit-h
CO2: 20kg pressurised tank , fabco nv
CO2 level: DC is yellow , CO2 goes through an airstone and into the three Atman flow pumps and spreads across the aquarium , co2 is set as high as it goes , if i turn it up higher my fish start to pass away.
Light: 2x45w t5 , 9 hrs-day
Dosing:
NO3- 45ppm
PO4- 12ppm
K - 60ppm
Fe from csm+b - 2.0ppm
70% weekly WC
My ludwigia ovalis is s in a bad shape, older leaves showing K deficit at 60ppm K dosed???
Am i overdosing something or what?
A while ago i've had a beautiful Ludwigia bush and after trimming it just stopped growing like before..
In the meantime i planted some microsorums, rotalas and bacopas, is it possible that they are K consumers and they take all the K from my ludwigia?
That maybe sounds stupid but i dont know what to do anymore..
On the other side i have Alternanthera reineckii that looks weak, lower leaves are wrinkling and dying, not very bad but the plant is not in top shape.
I have let the valisneria over it so it has some shade and also i turned one of the pumps towards that plant so it would get more co2 bubbles.
O yes, i forgot, my polysperma also showed some holes in the old leaves.
Anyone has some suggestions?
Please excuse me for my english.
....on one pitcure you can see my ludwigia bush as it was a month or two month ago...
