Hi,
I have a roma 240l with two 40watt tubes
It's a goldfish tank with goldfish friendly low light plants like onion plants, vallis java fern, anubias, crypts and amazon swords (only java moss didn't catch) And a big piece of bogwood
I have a jbl proflora easy 2 split to 2 rhinox 5000 and i recently bought an AE cal aqua drop checker and the two liquids match
I am using kno3 and k2po4 and ae trace elements in solution,
I do a 40litre water change every other day
Thanks Bruce
