Hello,
I am new to the Drak fertilizer.
So far i have bought KramerDrak and Eudrakon N.
I don't want to make mistakes, so i ask some guidelines.
My fishtank is a aquatlantis L:150cm, D:60cm, H63cm(effective water height)
Good for 520 liter netto
I have 4x 54 watt T5 lamps with reflector. 3x Dennerle special plant(3000k) and 1x Dennerle amazon day(6000k) in front.
I use 100% reversed osmose water an harden it with mineral salt.
I have Pressurized and computer controlled co2 and have precision dosing pumps for the fertilizer.
The goals is to have a fully planted thank with plants like Blyxa Japonica, Cabomba Caroliniana, Bacopa Caroliniana, Rotala rotundifolia, Red lotus, Ludwigia repens minor, Alternanthera Rosafolia,...
I have nog fertilized soil in the thank. Just some Dennerle powertabs bij the lotus ans some crypto's.
I have no special filtering materials like activated carbon or purigen. Also no Uv lighting or twinstar thnigs.
Waterchange: Weekly 40%
Values at the moment:
Th: 5°dh
Ch: 2.5°dh
pH: 6.1 (jbl co2 continu test shows green)
NO3: 5ppm
PO4: 0.2ppm
Fe: 0.1ppm (hanna photochecker)
I started dosing drak today. So the values above are from the old dosing system(!)
Dosing quantity:
Everything is dosed daily with dosing pumps at 10 AM(at start lighting)
(tank volume 520 liters)
Kramerdrak: 7ml
Eudrakon N: 7ml
KH2PO4 solution(4 grams on 500 ml): 5ml
Does that sounds a bit right?
I don't like to make mistakes direct from the start.
Will kramerdrak have enough iron in it?
