I've got the updated Fluval Spec V as well. I tried to find any PAR info about the new light, but was never able to (even Fluval didn't have it). I also have a 20 gallon long that has a Finnex Stingray on it, and the Fluval's light seems much brighter than that one. I've also had a lot more algae on this tank than the 20 long. I think if you get any higher light you'll probably just end up with more algae, but maybe someone else can chime in who've tried a different light.Think it would cause more issues then it's worth ? I have the 7000k one. I assume it's good for low light/medium plants.
I dose with excel daily. Think if I went with a stronger light, I'd just get more algae issues then anything else ? The tank is placed on the opposite wall of my kitchen windows. So it does get very filtered daylight during the day if I keep the shades open ( which I like to do)
I'd like to grow higher light plants. But I don't want to inject co2 in a little tank. I want to stick with excel.
