Default Another LIGHTING question and short Co2 quest. (at least I've narrowed it down...) :)

I have searched the forums and read quite a bit on the specific lights that I'm about to discuss... but there just wasn't any SOLID information that really made me say.. MAN that's the light fixture I'm gonna go with!! lol... anyway, here goes.......

Coralife NO T-5 Aqualight Double Strip Light 2x14W 24" vs. Current Nova Extreme 24" 2x24W T-5 HO



I know it's driving some of you batty just thinking about this question... but I'd appreciate some valid advice on the topic... Maybe some pictures and current or past experience with either light??

OK... as for what I currently have..........


I actually already have the Coralife NO T-5 Aqualight Double Strip Light 2x14W 24" on my 20 GAL High tank and I've been running it since this time last March... I LOVE the color contrasts the light provides, but it is definetely not enough light for most plants to survive in... I actually recently bought a Hagen GLO 24Watt single strip T5 HO fixture from Petdumb and realized that they burned me a new one as usual! It has a very nice reflector, but its just not as "colorful" as the Coralife. I'll be returning that whenever I get one of the new fixtures in.

So I'm either thinking of combining another Coralife NO T-5 Aqualight Double Strip Light 2x14W 24" with the one I already have OR combining the Coralife I have with the NOVA 2x24 T5 HO mentioned above...

What's your suggestions???????

I think combining the Coralife with the NOva could produce an interesting and vivid color scheme although it might not look as pleasing haveing 2 kinds of lights...

ALSO... My Nutrafin Co2 system does not seem to be producing C02... I have pure cane sugar and followed the directions to a tee... I have the system sitting in the bottom of my cabinet and cut the excess tubing... Is it taking longer to form due to the fact it's on the bottom of the tank and not attached to the side??

Any quick advice is greatly appreciated yall... Sorry if I'm asking questions that have been answered already...

I have the Nova HO fixture on my 20H and am quite impressed with its performance. I am still trying to get used to lighting for planted tanks though because I have been into reef aquaria for quite a few years where the lighting gets crazy high.

I would add a 2nd Coralife NO fixture.
It is plenty of light for a 20 gallon with two.
I run 20L tanks with two 30" models and IIRC they are the same bulbs as are in the 24"

I also think that you NEED two because the lights are so narrow that they don't get all the tank by themselves.

Plus as you noted, the color is great.

Honestly, I have not used the Current T5 HO fixture.
I have PC current lights which i like so I do like Current stuff, but I think that with the single reflector that they provide, the HO becomes a waste. I also think that they will be just as narrow as the Coralife as far as not covering the tank bottom well enough with just one, so I would probably say get two. However that might be too much light for your 20H.

If I were you I would stick with what you have and add to it.
Or if you like, add a current to the coralife and have one of each.

I don't have any experience with either of these lights and actually have been trying to decide between the equivalent Current and Coralife 30" fixtures. My purposes are different (lowish wpg on purpose) so I went with the Coralife. I'm glad to hear that you think it is a good light (I had read mixed reviews on this forum). It seems like most people here prefer the Current.

I did a lot of online checking and found the (30" sizes) Current for $58 at Dr. Foster and Smith and the Coralife for $37 at Big Al's. Lots of places had them, but these were the lowest prices.

I love them and Roy Deki swears by them and if they are good enough for him....

Most people like the HO because it is HO and it is a bigger toy, know what I mean, Heck, I have HO
Not that they are bad and there is a place for them, but over small tanks, I don't think it is needed.
And those Coralife's do a darn find job and are cool and SOOOO low profile and CUTE.

Check out this thread about true light needs from some real pro's

http://www.aquascapingworld.com/foru...low-light.html

Really interesting and it reflects what I have to come to believe. Most of us strive for way too much light to really enjoy the scape (unless watching plants grow insanely fast is your enjoyment)

You can see some links to some of the posters tanks, I am talking 75 gallons with two T5 HO lights and that is all and the tanks are awesome. That is all I use of my Tek BTW over my 75 gallon.
I would not have gotten the 2 lamp fix, they cost almost the same and this gives me more options like mid day blasts, but I use mostly just the two lamps.
