T5 bulbs for planted tank

I'm looking to buy one lamp for my 85 gallons tank (21 inches height), 4 bulbs T5:
2 Plant Grow
1 6500 K
1 10000 K

It's ok? or change the 10000K for another 6500K?

Any combination will work fine, it all comes down to personal preference and how you want the tank to look. A little offtopic, but that seems like a ton of light for your tank

I have a 125 and I rarely run more than two bulbs at once. Mainly because I have a 4 bulb fixture with 2 switches and 4 bulbs on at once is too much light. If you can find a 3 bulb fixture with 2 switches and have two bulbs burning all the time and one bulb for a noon burst it would help you more. Catalina Aquariums can custom build for you and they are decently priced.

mmm Do you think that? My iniccial suggestion were only three bulbs, but I finish looking for 4 because the .5 watts/litter rule (2 watts per gallon) and for the height of my tank, I wan't to put in cryptocorynes, echinodorus, mycropterus windelov, and glossostigma. Inhabitants: Altum Angel (around 6) some German Blue Rams and one group of tetras.

If you can find a 4 bulb fixture that runs on three switches that would work too.

Have you seen this thread here? http://www.plantedtank.net/forums/li...t5-t12-pc.html

I think you'll find that two T5HO bulbs over almost any tank will give you 'high' light

Precisily is in Catalina Aquarium where I want to buy it, really I don't know if three or four bulbs, I'm from Mexico so I really want to make a good decision and by the way take advantage from the shipment.

I have a Catalina 3x24w 24" fixture hung 15" over my 60-p and about 30" over the substrate. I only run the bulbs for 6 hours a day. I also have a Catalina 4x24w 30" fixture over a 37g that is on legs over the tank so about 3" above the tank and 21" from the substrate. This light is run with 2 bulbs for 4 hours and all 4 for 6. I have pressurized co2 and I hope you do too. Otherwise you are going to have an algae farm.

Hi Arturo, I had the same problem as you. What to get..3 bulbs or 4? I have a 90 gallon, 48x18x24 and I called Catalina and asked for their advice and they said to go with 4 bulbs, 2x 6500, 2x plant gro on 2 switches. So, I took their advice and am totally happy I did 4. I run 2 bulbs 8 hrs a day and blast the other 2 in the middle of the day for 3 hrs. My plants love it and I have the ability to control the lights. I can run all 4 lights all day but you better have high c02. I just like the ability to control my lighting. Maybe get the 4 bulbs and have them on 4 switches? That would be the most ideal...full control.

Best regards,

90 gal, eheim 2217, pressure co2, 4x54w T5HO.

In regards to co2, I studied this forum to find who is using what. I decided to go with a Rex Grigg regulator and found a 5 lb co2 tank on craigslist...total was about $150. I made my own DIY rex grigg reactor and bubble counter for $15 total and ran it inline with my eheim outlet. Before, I was doing a DIY Co2 and that was a failure for a 90 gal...no control and not enough Co2. Don't go with a bubble ladder...the amount of co2 produced, the ladder can't keep up...reactor is the best way to saturate the co2.

90 gal, eheim 2217, pressure co2, 4x54w T5HO.

Thanks to all the replies, finally I got my lamp, 4 T5 bulbs: one 10000 k, 2 Plant grows and one 6500K; with 3 switches so I can light on 1, 2, 3 or the 4 bulbs. I am very happy with it.
