    CO2 wont mess anything up unless you have high light and fluctuating CO2 levels. I think you will have about 30-35 micromols of PAR with no water in the tank or from about 35-40 micromols with water in the tank. (Water concentrates light and allows reflections from the glass to increase the PAR)

    Hey Hoppy,
    A couple weeks ago on my thread you posted a link to a chart showing the PAR's for CFL bulbs and noted that a PAR of 35 or below would keep me from worrying about CO2. At that time I was planning on using 14W bulbs but I ended up buying 19W bulbs. The bottoms of the round clamp light reflectors are about 17 inches from the substrate and the bulbs themselves are probably about 19. From the chart it appears this puts me at a PAR of about 35 but I thought I'd ask you to be certain. Also, I was thinking of adding a little DIY CO2 every now in then, will this mess anything up?

    In case anyone reads the conversation I have with Hoppy below - these Coralife T5NO fixtures are growing plants real fast! It's not super bright and growth is a little leggy, but I have almost 0 algae (8 amano shrimp is the only kind of "algae crew" in there at this time and the only place algae exists is on the glass...plants wood are CLEAN) - I hung them 1" above tank.

    Thanks Hoppy! Don't think I would enjoy trying to keep up with T5HO Growth at this time, maybe in the future, near or far, but this is great lighting for my first foray into planted tanks!

    If you raise the light above the top of the tank, a 24 inch long light is all you need - the light spreads out to cover the whole tank.

    Hoppy. I hope you don't mind me sending this PM, but you seem very informed about lighting. I was wondering of you've heard of anyone with a 29 gallon tank, which is 30" in width, using a 24" light? It seems 30" T5ho are a little more rare. Thanks for any help! I appreciate it.

    A good T5HO reflector used with T5NO bulbs, driven at T5NO power, should produce as much as double what a Coralife light produces. Great reflectors almost triple the light from a bulb. Coralife reflectors are poor.

    As luck would have it, Amazon has them

    Cannot and will not argue! That seems great then. Hopefully I can find two of the coralife 36 inch fixtures ; I can replace the bulbs with any brand so going out of business doesn't matter right? Is a reflector from say a catalina 4 bulb t5ho fixture (with t5NO bulbs) going to be signifcantly brighter or should it still be in that 40 mms range you recommend? I can get a custom fixture there but are their reflectors "too good" for a four bulb spread?

    Look at some of Tom Barr's (Plantbrain) tanks. Those are now all running at 40 mms of PAR or less. He uses high CO2, very high surface rippling, and other tactics to get high O2 levels in his tanks. Then, he grows whatever plants he wants to grow, and sells the excess regularly. I can't see any way to argue with that success.
