I have a 40 gallon I'd like to turn into a planted tank... lighting?

Hi! First post here. I saw this website and figured it could be really useful for setting up my tank.

I have an old bowfront 40g I really want to turn into a planted tank.

I have a t8 fixture(i think? The old bulbs in there are about between the size of a quarter and a nickel), and I would like to go for medium lighting.

Heres my fixture: Attachment 208769 (sorry about the dustiness of it, i need ot wipe it off)

Each bulb is about 18 inches. http://www.drsfostersmith.com/produc...fm?pcatid=4489 I was thinking about getting two of these. Would this work? How many watts per gallon would that be, do you think?

Well...

2x15w = 30w/40gal = .75 wpg

Wpg isn't used very often but even so you'd have pretty low light. Might not be able to grow much other than the very low maintenance plants.

Lots of different options to go with nowadays with T5s and LEDs becoming more of the norm with planted tanks. Hence why Wpg is becoming outdated because it doesn't work well for more efficient lighting. I wish I could give you a more specific suggestion, but I haven't chosen lighting for a planted tank that size.

Have you read Hoppy's thread about PAR? It's a lot of text, but a good source of info.

Finnex Fugeray or Current Led plus would be good ones to check into. They offer good light without having the need for co2. They may not grow the highest light plants but will grow the majority just fine. As for your t8 lights, those precede my experience in this hobby. You would probably be able to grow Java fern, anubias, hygrophila, and a few other plants if you wanted to stay with the t8 fixture for now. Growth will be slow but it is possible.

Ah, okay. Thanks for the info. I figured my lighting would be pretty weak.

Anyways, in t5 lighting... is there any way to get a t5 set up without spending 200-400 dollars on equiptment? I've seen people use what pretty much appear to be lamps. Is that more inexpensive?

ZooMed makes a 2x39w t5ho as well, its 80 dollars on petco's website. Don't know if thatd be better than the one on no ebay links allowed(deleted said ebay link because i found out that posting ebay links isnt allowed ^^ sorry about that!)

The big box home improvement stores like home depot carry multi tube t5ho or t8 shop lights that may be a bit more affordable. They don't mount like a standard aquarium strip light so you'd either have to make a hood or hang the light.

after this I'm not sure what answer you want.. Using 2 of those would "only" be 160-ish though also in the range of a fair LED fixture. Even one way more than doubles your current setup..

As to the "better" question: Weak point is usually the ballasts.. which is probably similar in all those fixtures (if not from the same factory..)
