Nice tank Mervin . I especialy like the first pic planted setup.
Is that red plant on the firs pic the notorious Rotala Macrandra ? Hoe did you manage to keep it alive w/o Co2 ? How long did it last ?

Not sure if this method of inserting images works but if so then this was my low tech tank.

I keep variety of plants in a good state in my discus tank without any Co2 or any additional fertilizers .
All I have to offer my plants is a good light source and a bit of rich nutrient soil in their pots to keep them well fed.

Here is a pic of my tank to encourage you to go without CO2 for your discus sake.

Beautiful fish here Filip. What type/strain are the two to right of photo?

Thanks for your inputs guys, didn't think i'd need co2 but wanted to confirm. Oh and don't worry about the 'hijacking' cool overflow design.

I've used CO2 in a discus tank some years ago and found it hard not to stress the fish during wc since the CO2 lowers the pH. This means you have a pH-rise with every wc.

They are a cross of Rose red with Piwowarski Red turquoise discus .They got the brownish look from the rose red and the blue striations up and down their body and fins from the Red turquoise .
Theese and similar lookin Brown based discus are ussualy sold by the name Alenquer discus on the market.
