I used a Finnex Planted Plus clip light for about a year and some of the LED's started to fail. So, I recently purchased a Kessil A80 Sun, which is now my light source...great light! Powerful though, I run the light for 8 hours at about 70%. My CO2 set-up is a paintball tank with a Green Leaf Aquariums regulator, diffuser, and bubble counter. I run the CO2 at one bubble per two seconds. I dose 4 drops of iron and 2 drops of potassium every other day...seems to work for me. My home is on a well, and the water quality is horrible, so I use distilled water and Equilibrium for water changes. I have way too much money invested in this little tank, but as long as my wife doesn't know...its all good! Thanks for the compliment.
