Hey guys, I was wondering if you could help me with a problem I am having. I have recently had a 15g planted tank that has really started to take off. I have fallen in love with the planted tank idea. So I have decided that I want to convert my african cichlid 75g into a planted tank :icon_eek:. I know its a huuuge tank and it prolly will be a big project but thats where the fun is.

So here is my dilemma :icon_roll

I have a regular dimension 75g that is 48" x 18" x 21" and this is what I need to purchase a light fixture for :D. I saw in this thread (http://www.plantedtank.net/forums/showthread.php?t=105774) that the T5HO Dual Lamps would be "High Light". Does anyone have opinions on this? Would that be enough light you suppose? Or do you think I would need to purchase a fixture with more lamps?



Also this is what I was looking at (http://aquaticlife.com/products/286) and was thinking of getting 2 or 1 lunar lamp in it with either 2 or 1 lunar bulb. The timer on this one will allow me to set which lights turn on when.

2 t5ho is more than enough. I spent way to much money on my 4xt5ho only to later learn that wpg is a myth.

I'm now looking into led lights because the t5ho fixture cost like 40-50$ a month to run.

Hmmm do you happen to know any 2 lamps that have built in timers?!?

Where do you live that your electric rates are that high? Even if we assume you have 400w total, at 10 hours a day for 30 days = 120 kwh. Your electric company must be charging you near .50 kwh....eeek!

I have that 4x54 fixture that you originally mentioned.

It's a great fixture. The 4 bulbs are arranged in 2 banks of 2 that are individually controlled by the timers. That gives you a couple of advantages. First it gives you more flexibility over amount of light provided. Need higher light, run some overlap of all 4 bulbs mid day.

Second it lets you deliver light from different source locations over a larger spread. That lets you deliver light into more locations than you can from 2 bulbs, reducing shady spots and legginess in stems.

Third it lets you run different sets of bulbs. I used to have different colors...daylight bulbs that I'd run in the morning and pinker bulbs in the evening for a different, more subdued light in the evening.

I have one for sale in fact. Search the swap n shop. Still available.

mitch, that's a good fixture for your size of tank, and has the flexibility. The 6.5K bulbs are good.
Running all 3 bulbs together may be a touch heavy-duty and could invite some algae issues, but running just 2 bulbs for say, an 8 hour lighting period should be just fine, imo.

Ya exactly. I knew I diddnt want to have a 4 light fixture for these principles:

1. Money... The aquaticlife 4 light t5ho was much more expensive. I got this light with the 2 switches on it and 2 timers for $160 less than the 4 lamp. Thats HUGE.

2. Convenience. I knew I diddn't NEED more than 2 bulbs. However I got to thinking and was wondering what would happen if one day I did NEED an extra bulb? With this I will the ability to have the flexibility. Also I can run a Noon-ish burst for an hour or so if I really want to.


So I agree with you entirely tho about running all 3 would invite algae issues. But the price was great and the ability to be flexible really helped me decide on that fixture.
