DIY CO2 ideas!

Alright. So I'm about 4 months into the hobby. I currently have a 25 gallon moderately planted, running a fugeray. I'm dosing EI however I will admit I'm only doing it once a week because I was having issues with high nitrates even after water changes. I actually think my API master is off...but I'm not sure. Anyway, I've been wanting to take the plunge into DIY CO2. I'm really struggling with what I think is Hair Algae.
Here are my concerns.

The tank is already 20" high and the stand is another 3 or so feet high. I'm wondering where I can place my diy co2? I'm worried that if I place it underneath the aquarium on the shelf that I will have issues with pressure or siphoning? I would need about 4 feet of airline tubing if I place it underneath. 2 feet to the top of the tank and another 16 or so inches down near the substrate. Would that be an issue?
I was thinking of somehow creating something that might hang on the bank of the tank that could hold the CO2 but I'm not exactly sure what I'd do!
Any ideas are greatly appreciated!

I had my DIY CO2 underneath my aquarium without issues as far as the pressure goes. As long as you have a check valve in line you won't have any issues with the "siphoning".

As Bandit said, check valve would prevent any siphon problem. If you wanted to make something to hang the 2 liter bottle from the side of your tank, you could probably use a wire hanger. Maybe put a sponge under the hook part, so as not to scratch or mess up tank rim. Then just bend the bottom part into some form of a loop, similar to those wire things used when dyeing easter eggs. May look a little ghetto though, just hanging out on side of tank. Nice tank btw, looks good, I also have a Emperor 280 filter, does a good job for me.

Also another option, if you don't want to do the DIY CO2, you could try Flourish Excel. It's basically liquid CO2, and helps as an algaecide. Look it up here on the forums. Many swear by it. Good luck.
