Well, plans didnt end up working out on the 100g acrylic I was going to use. I was not able to repair the leak. SOooo I decided soon to pick up a standard 125 gallon, 72w x 18d x 21?" tall. Figured for lighting I need med to high lighting. fertilized and co2 injection. going to use two 36" lights T5HO, question is, total of 4, 6, or 8 to acheive my lighting needs?

You should think more about how much light you want to use. If you have 40-50 micromols of PAR at the substrate, along with good CO2, and good fertilizing, you can grow whatever plants you want to grow. But, that light level is low enough that any algae that begin growing will do so at a slow enough rate that getting rid of it will be pretty easy. The plants will also grow at a slow enough rate that you may not need to prune them every week. If there is a reason for using more light it would only be to attempt to get as intense a red color as possible with those plants that become reddish only with lots of light and fast growth.

You can get 40-50 micromols of PAR with a single T5HO light bulb about 22-24 inches from the substrate. With an 18 inch front to back depth tank, one bulb will not give very uniform light from front to back, but two bulbs, widely spaced, 8 inches or so apart, will give you good uniform lighting, without exceeding 50 micromols by too much.

One way to do this is to contact Catalina Aquarium, http://www.catalinaaquarium.com/store/index.php?cPath=71 and have them build you a pair of custom 36 inch long lights, using a wide housing made for 6-8 bulbs, to get the two bulbs widely spaced.

i would always get more than you need and turn some off, hoppy is the lighting guru.... but if your going to buy a new luminaire then get a 4 tube unit and start off with 2, better to have it and not need it..... IMO

If you don't need it, why get it? Once you have it, the temptation to use it will be very strong.

Yea I was reading that chart and getting a rough idea. Its still a lot to take in! As always thank you for the info. Hmm the idea of getting the more bulbs isn't to bad of an idea either. Probably go with the 4-6 bulb route. Thank you again!

you are right but its cheaper to buy a unit with more bulbs now than replace the unit when you change tanks, hang it higher or want more light. The grass is always greener on the other side...... so build a bridge now :hihi:

Found the lights I am going to go with for now, my question is one set comes with the pink pepto "plant-light" and the other uses the 460 Actinic. I like the effects the actinic give the tank enviroment. Each one also uses a 10k bulb. Would the Actinic work or should I go ahead and get ones with the pink pepto bulb?

Still debating on the Porshe....I don't need it, but I am very tempted in driving it, however the idea of constant tickets doesnt thrill me.

The 460nm blue would function fine. I suggest getting both bulbs so you can make up your own mind. Spares are good to have anyway.
