i just switched out 2 hagen life glo and 1 650nm roseate bulb with 2 giesmann middays and 1 aquaflora. the life glos had a huge green spike in the spectrum. the middays have less green and more red and blue. i grew anything i wanted with the life glos, so im not knocking them. there are better bulbs out there is all.
Is it better to get two bulbs of the same color/brand or to mix two different colors/brands? Or does that depend mostly on personal taste?
Does anyone know much shipping usually costs from Aquariumspecialty.com for 48" bulbs?
Mixing bulbs is just a matter of personal taste.
I think shipping for 2 bulbs was around $9 last time I ordered. You can just add the bulbs to your shopping cart and it will show shipping charges prior to checkout or you could call or email them. I've spoken with them by phone a couple of times and they're always very helpful.
