I am looking into starting a 55 Gallon Aquarium this weekend and was wondering what alternatives there are to CO2 instead of having a tank and feed? I have heard something about Seachem Excel...any ideas? Thanks!
I have to agree with Bk. IME with my 55g I started with excel then DIY and after a couple of months of less than desirable results I went pressurized. The best thing I did for myself! I have had 10lb tank on for like 4.5 months and I haven't even seen the pressure go down!
Depending on the plants you plan to plant in your tank and how fast you want them to grow will determine whether you need to add C02. Some plants need a lot of light and ferts in order to grow well or show off their colors. In order to do this you need to supplement the C02 in the tank. Since I started using excel it has given all the growth and color I currently need or desire. However, the daily dosing does get tedious after awhile and now I'm considering pressurized C02. I would suggest starting out with good lighting, a fert routine, and excel just to see the effect and growth rate does what you want. Remember the faster the plants grow the more thinning, trimming, etc involved. Just my opinion as usual. Good luck.
