WoW... RM8000 for a planted aquarium.... and you gave up on it?

Johnson, I had links to 2 sites discussing DIY CO2 injection systemsin my previous post. It's basically creating an alchohol brewery with yeast and sugar in a 2L Coke bottle, which will release CO2 into the aquarium. U won't be able to 'switch off' the CO2 like in the electronically controlled system (U don't have a solenoid in the DIY system).... so what I've done is put an aerator and airstone on when the lights go out. (using a timer, set on opposites.)

The yeast solution will produce enough CO2 for about 2 weeks and this is only economical/feasible if you run a small aquarium. 2ft - 2.5ft aquarium. If you wanna go with the 4ft aquarium, u're better off using the compressed gas system.

BTW, there are also sites on the internet which detail DIY compressed CO2 systems. Just buy everything (gas tank, control valves, pins etc) from the Gas producing company, and make the reactor ane everything else from household thing..... instead of buying the Dupla or Sera system.

Most importantly like webmaster has said, u need light and lots of it. I have 60W lighting on a 2ft aquarium. I prune my plants weekly and bring it over to the fish shop in exchange for frozen bloodworms.
