That light you posted will def. not be enough. On my 29 gallon i run a planted plus and a coralife dual t5 no and get on the lower end of medium light.
Puckhog, why do you have coralife bulb is 10000k useful?
And why is your tank only "medium light". Is it because of your plants?they require a lot? It looks like i have a lot to learn any books or websites good to learn about plant lighting?
The coralife doesnt mean anything. All t5 nos and hos are the same thing some people just say coralife bulbs last longer. I have one bulb 10000k and one 6700.
Anything between 6000k and 10000k willgrow plants fine. I already had the 10000k and liked the whiter light it put out. The planted plus led fixture has 7000k white leds with blue and reds mixed in. I originally had the same problem as you. I wanted to plant my 29 but didnt want to spend 150 bucks on lighting. I started out with just the dual t5 no and it could hardly grow anubias. Once i added the planted plus i was finally getting enough par to grow medium light plants.
You could do the clamp on dome lights but would have to build a canopy. I would say 3 23 watt cfls. Would be sufficient and give you better light spread than 2 60 watt bulbs.
Oh ok. The thing is i have useless 12000k bulbs the guy at my fish store recommended. They were expensive! I dont think i can afford planted plus now. Ill see if these cf bulbs are ok.
The 100 watt bulbs will not work. Go with 2-3 23 watt bulbs. Also be aware that the heat may crack the glass lid. Also what plants are you planning to keep? This will help determine how many bulbs you will need. Also if the tank is in a bedroom or smaller space be aware the bulbs as well as the tank can make the room pretty cool. I have 2 tanks in my bedroom. A 4 gallon and a 29 gallon. Both tanks at one point had flourescent lighting. After switching over to led the temp in my room dropped 2 degrees
But they are not 100w they are 23 watts. They are equiv to 100w incandescents. Am not sure what plants im going to get exactley because someone is going to give me a bunch of plants , but I might want carpet plants. I know thse require a lot of light.
I also have a 29g and dose ferts and co2. My DIY fixture has 4x23watts 6500k cfl, bought from Walmart. They do ok. You can get a good carpet with different kinds of plants with above lights....like dwarf sag, s.repens, and baby tears (HM) to name a few. If you want to do baby tears (HC) you will definitely need a more powerful light like BML since our tanks are so high. I consider my light-low medium.
