Hey everyone it looks like I'll be getting 2 30" Finnex Planted Plus 24/7 lights for my 72" 125g got my birthday. Currently I'm running 2 24" 6500k t8s on the stock hoods. The tank is pretty dark and my plants aren't doing much.

I have java fern, anubius, and water Wisteria. I dose root tabs and micros/potassium.

I plan on using the 24/7 cycle. What kind of lighting will this put me at at a 22 or so inch depth? Will I need c02 ? The tank should also be much brighter I'd think? I want to keep from having to do c02 if possible.

I had quite a bit of algae with my regular planted plus but the tank had a much shallower depth.

Also would amazon swords work well? Never had good luck with them. Any other plant suggestions?

Thanks so much for your help. This forum is great.
 
Those two 24" T8 fixtures would put very little PAR/PUR into a tank of this size. The Finnex planted + fixtures look promising, but that too would still be in the low-light category. Not a bad thing at all, you'll just have to gear your plants towards it. Amazon swords will do fine with low light, but they get HUGE. I've got one in my 55g that would take over the tank if I didn't cut it back. Nice thing about LED is you don't have to change lamps ever. T8 and T5 you should change lamps yearly and some do it sooner. Here's the amazon sword in my 55g. Pic is only about half of the 48" 55g tank:
 
Mine have never grown that big. I use rutabs from Peabody paradise. Mine always would be covered in algae and small size
 
I currently am running four 36" Finnex planted Plus on my 125. This gives me enough light for swords, wisteria, pennywort, anubis etc. Pretty much any low light to medium Plant. I also dose with excel every other day and comprehensive once a week.

That is a beauty of a tank freak78! How long to you keep the lights on? I'm surprised 4 of them don't create a bunch of algae w/out real CO2. I dose glutaral/metricide, but I'm pretty sporadic with it. Also use Seachem trace and seachem comprehensive liquid ferts at times.

Yeah, if this was with the T8 fixtures, that's why. Not quite enough light depending on tank size/depth. People do have great success with 48" T8s for planted tanks though.
 
I run the lights a total of 6 hours. 1.5 hours in the morning them 4.5 in the evenings. When I first started to run 4 lights I had algae but I've found the happy medium with the lights, growth and ferts. So now it all works out.
