I used to have a 125 planted discus tank with CO2. Back then I used a Current Satellite T5HO unit (I can't remember the model) and had okay results. If you're on a budget the new Current Freshwater LED+ Pro products look pretty cool. You may consider two of the 48/60 inch units; they run between $175-$250 online.
If price is no object go with Kessil. I now have a 75g hi-tech tank with two Kessil A160WE Tuna Suns and I am thinking about adding another or one of the new A80s to fill in the gaps. For a 125 I would suggest three of the A160WE Tuna Sun ($239 each) or if you really want to get that S. Repens carpet growing, the A360WE Tuna Sun instead, but three will set you back about $1200. Plus you'll want the Kessil spectral control module ($99) if you're not using an Apex.
I will never go back to fluorescent after having LED. Changing bulbs every 6-12 months to keep the quality of light up got old (and expensive) really fast.
I would love to to hear other suggestions; especially on the lesser expensive end as I know that most people are not willing to spend the amount needed for Kessils.
Thanks for your post. Hey yeah really want a light bright enough to grow any carpet I want. I've wanted kessils for years while keeping reef tanks, The price is a bit out of my my budget though. I have mixed feelings about leds for my aquariums at the moment. I've used T5HO fixtures for years with great success. I've tried leds on my reef but had better success with T5's. I've tried leds on my planted systems as well and have had success with anubias and Java moss(cuz those are the only plants I've grown under them). I feel more partial to the T5's for some reason.
How is the shadowing with the kessils?
I fear i would end up buying 3 a160s and then have to suppliment with, like you said a couple a80s or a couple t5s In order to get the spread right.
What about a hybrid setup?
Have you seen anyone in the planted aquarium community using them?
Like possibly a Bulb in the front with leds in the middle and another Bulb in the back?
And then there is still the issue of trying to cover a 6' tank with an even spread...
I do have the option to set this aquascape in my 75g. It would be way easier to light!
What should I do?
