I have a low tech planted tank containing some java ferns, anubius and crypts. The lighting is very low, only 17 watts t8 on this 38 gallon tank. While I enjoy not having to deal with algae or trimming the plants are not as green as they could be. Actually they are turning brown. So I'm thinking of upgrading my lighting. Nothing drastic though, as I only want to maintain healthy plant life and not after vigerous growth of my low light plant choices. I'm looking at a t5 that is 24" and a single bulb for 24 watts. Although my tank is 36" is this a factor since it's not going along the entire length of the tank? The 36" version would give me more light than I'm after. I'm looking at t5's versus say a higher watt t8 because of efficiency and a t8 would require a double strip and wouldn't fit onto my integrated hood/cover. Would this be a good choice?

Thanks, I do dose excel daily and that's all I do. CO2 is not a route i want to take. I actually got the 36" fixture with a single 39 watt t5. It is extremely bright in comparision and I'm not sure if I like it, the angels were hiding and actings as if a ufo was about to land on them. Every little scratch, algae, poor condition plant, debris etc really sticks out. Maybe a hardscape or decorative(fake plants) is more my thing. Still undecided.

THe only way to use the brackets to raise it is to remove the lid becasue they clamp onto the edges. Since it's not rimless, has a centre brace, and a hob filter, and is generally caked with gunk where the lid would be it's not a clean look so I'm going to have to play around with it. I've seen that chart and sitting only an inch or so above the lid would be alot of light so I'm going to have to figure something out

Ya that would be cool, problem is the tank is in my front forier which is two storys high. Maybe I can mock something up. Thanks

Also regarding the chart in the link...based on the chart a single t5 on a tank of 20" would be low light at 4" above the tank and also low light at 12" above the tank. So is that to say that whatever you like better or works for you, either or is the same thing basically?

Well there was no real practical way of mounting this without building something to hang it off. Even with the top removed using the brackets the most you can get is 4" from the top which was still way to bright. I personally feel that s.american fish dont' show best in such bright light. I was perfectly happy with the 8000k 17 watt t8 bulb looks wise, just wanted healthier plants. Even though they are not in perfect shape, they are decent enough for me so I ended up returning the fixture the following day. Just looked very unnatural to me, and showed every little scratch, algae, dirt etc in the tank bright as day. I could see the light glowing through my frosted glass window on my front door from down the street! Seeing as I only have some java ferns, anubius and a couple of crypts(the crypts actually grew in here), I think i'm just going to leave it be for a bit and see what happens. If in a few weeks everything has died then I'll have to decide between a simple woods and rocks hardscape or a tastefully done decorative scape(plastic plants).
