Hey everyone, just a quick question... While my tank is cycling I'm going to add some plants and a DIY CO2 system, it looks easy. Will I still need to leave a CO2 system in a heavily planted aquarium once the plants are fully grown and fish are added (after it's done cycling)

What's your wpg going to be? If it's anything over 2wpg, you'll need CO2 as long as you have plants. The plants will never be "full grown", they'll always be photosynthesizing and growing new leaves or fronds or whatever they grow.

Oh the bulbs I have right now will only be running 30 WPG, guess I need to get some better lighting, lol. And I did a lot of googling and found some stuffs out. Thanks for the reply, it got me started on research. XD

Do you mean 30 watts or 30 watts per gallon?

You're going to need some pretty powerful lights to have a heavily planted 70g tank. Even if you just grow low-light stuff like java moss and java fern you'll need at the absolute least 70 watts. High light plants are in the 3-5 watts per gallon range, so 210-350 watts.

It is just 30 watts for the 70 gallon, which is less than .5 per gallon, so I know I need to upgrade.
I'm on a budget can I use the newer curly fluorescent bulbs to DIY my lighting?

Compact fluorescent wattage is considered the same as traditional fluorescent tubes. Unfortunately, you're going to need a T5HO (high output) fixture to get up to the kind of wattages you need for medium and high light plants, and they aren't exactly cheap. When looking at them, the wattage listed for T5HO is roughly double standard wattage.
