The Incredible Coral Man Posted April 28, 2007 Report Share Posted April 28, 2007 hey just wondering... is it essential to have a CO2 system for a planted tank? would just adding fertilizer be good enough? Quote Link to comment Share on other sites More sharing options...
Plantman Posted April 28, 2007 Report Share Posted April 28, 2007 fertliser and lighting are more essential than Co2. but again there are those who has neither special fertliser and lighting and yet their plant thrives. if you just got started with planted tank, you can have the Co2 at the later stage when need arises. Co2 is there not to ensure plant's growth but is there to compete against the dreaded algae but still there is no guarantee if the aquarium keeper did not have a proper maintenance. Co2 does not eradicate algae but to keep alae under control and at the bear minimum. if are well into planted, you can always start a DIY Co2 which is not expensive like the pressured co2 system. maybe some fellow members of FNZAS will share some light for you and others who wants to know. have a good day Quote Link to comment Share on other sites More sharing options...
Caryl Posted April 28, 2007 Report Share Posted April 28, 2007 You can get spectacular results using CO2 but personally I have a well planted tank which has never had fertiliser added to it (apart from fishy poo), just has 4 daylight fluoros and no CO2.

alanmin4304 Posted April 28, 2007 Report Share Posted April 28, 2007 If you want to use CO2 you will need very little aeration and strong light. Most plants will grow quite well without it. Quote Link to comment Share on other sites More sharing options...
