Hello All.
My aquarium 540l {water 370-400l] 150x60x60
Dosing Ei index micro and macro 3x times a week{Every sunday 50% water change] - Only RO water { no added equlibrium booster] - Using 35 kg Seryiu Stones!

Aquarium equipment:
Lights 6x80w T5 tubes Ati sunpower unit {lighting 8 hours each day] lights 55 cm above the water level.
Co2 from presurize bootle 2h on before lights on , 1h of before lights goes of!
Tropica soil = tropica ferts sand = Npk tablets in a substrate aded.
Filter 2x Oase Biomaster thermo 600 ..Flow 1250l/h { media Bio media Eheim,Seachem purigen 6x,Seachem matrix,Eheim bio balls] ,connected to the lilly pipe and skimmer.
First filter is coonect to the external reactor with bio media in it so real flow of the filter is propably arround 500l/h
will have to add adjustable flow external pump connect to the filter {remove it the impeller] as the reactor have problem disolving all co2 and is filled up with air on the top and boobles comming out from the lilly pipe outlet.
Second filter real flow 600l/h its full of media.
