Its so dark... cannot find replacement florescent
Hello people,.

I have a 30"x12.5" 20gal freshwater tank. Guppies, Clownfish, Neon Tetras. I just ordered a fermentation Co2 system. Heres my problem:

I'm using a 28" lighting fixture that has two Coralife "T5" florescent tubes (One 10,000k bulb, and one "Actinic bulb") The tubes are exactly 27.75" from one end of the pins to the other. Recently the 10,000k bulb went out.

The store that sold this to me went out of buisness, and I cannot find replacement bulbs in this size and length anywhere. Can anyone point me in the right direction? If it helps, this is the model/serial number of bulb: F18-T5-BP (google search leads nowhere)

I am starting to wonder if this lighting fixture was ever meant for a green planted freshwater tank anyways, but I really dont want to throw down a ton of money on another one. (I will if its really needed)

My guppies and clownfish will be eternally thankful for any assistance provided.

Home Depot or Walmart (look both in the home lighting and the pet sections)

I have seen good plant lights at both of these places...they may not be advertised as such, but if the parameters are the same, it will work, and be much cheaper too...

Cheers. I checked the pet section at Walmart (hate going there), but had no luck. I'll check Home Depot, and if that fails, the lighting section at Walmart... and will report back tomorrow :wink:

Do you mean clown loach? Clownfish is salt water and won't survive in a freshwater tank.

If it's a clown loach then these guys need to be in groups, best if you can have six, and they also get huge so a 20g wouldn't be anywhere near large enough I'm afraid.

Did you check on line? I have some specialty bulbs in my home, not for the aquarium. The only place I can find them is on line. Try Googling your type of bulb or just light bulbs and you'll get lots of places to try. Some will even special order for you.

Best of luck!

Yeah, clown loach. I have two. I've had them a year and they have not grown significantly. I did the radiohead avatar, btw.

Hm.. after some googling, I just read that the 10,000k bulb is not reccomended for planted freshwater tanks. My lighting fixture also has an "actnic" bulb. Did the guy at the petstore sell me a saltwater light fixture, knowing i had a freshwater tank??

What kind of lighting should I be using for a planted tank? :(

^Err, I meant "dig" the radiohead avatar

Finally did enough searching to figure it out....

30" fixture = 28.1" . So I needed 30" bulbs.

After searching more, I saw that "ColorMax" and "6700k" are the key bulbs for freshwater growth. Hmm.. Is that why my plants strugle so?

I think I paid $120 for this fixture, that is worth $50 and was not the one I needed. . now that store is out of buisness. It is no wonder why. :evil:

I've ordered colormax and 6700k bulbs. Between that and the Co2, I cant wait to see the difference it makes in the plant growth.
