which is best for plant growth ,all white blubs or actnic blue blubs or one of each ?????

 

[whitedevil]

neither.

what plants do you have? what size tank?

 

[acati]

30g tank mostly stem plants about 20 - dwarf sag 20- a.nana 6--no CO2

 

[acati]

why neither? must have light--forgot about the java fern and crypto--have mostly live bearer fish,don't see to many babys,but a lot of fat healthy fish--but with all the plant growth they are hard to see--right now I am using 2 strip light from a yard sale both have 15 w,cool white blubs-was thinking of upgrading to more watts,better lights

These work good
We use them at work
Fluorescent T-5 Lamp - 6,700k - 28W - 48 in.

White bulbs work just fine. Actnic are for reef aquarium. White bulbs give off the full spectrum. I use T5 10,000k bulbs (white) and 6700k bulbs. The 6700k bulbs are slightly yellow. There are also "plant" bulbs that are pink in color. Shoot for about 1-1.5wpg since you don't supply CO2.

lets put it this way, dont waste your money yet.


what light do you have on there now? an all glass aquarium strip light with an AGA bulb? AGA bulbs are 15w yet are 8500k on the color temp when makes them perfect for low light low tech tanks.

I got a 26g with plants as well, I use the AGA 15w stock bulb but I am getting a GE 6500K bulb for a backup, its the GE plant bulb, sell for like 6 bucks at wal-mart.


check what you got first, you might not need a bulb period.
