I use to use Excel on my 55g with good results and I dosed 2 caps daily and after large water change I'd dose the 5 caps.

Try increasing Excel like mentioned.

Well re-reading your first post you have the Glo fixtures right, which is T5HO and you have 4 bulbs. You should have plenty of light and its the carbon source that's being short most likely. You are probably in the moderate/highlight range. I'm not the best with light determining. Lol

All you can do is make small adjustments and observe.

You may want to pickup Potassium as well and Iron.

Switching to dry fertilizers would be even better.

That is a good experiment to run.

I'll dry the increasing in Excel and see what happens. If they seem to respond well, then i'll crunch some numbers on dosing excel vs a pressurized set up to save $ in the long run.

Did you mention that after a large water change, you dose 5 capfuls?

I think i'm in the med-high light range as well, but the issue I have is the fixture itself is 2ft long w/ 18inch bulbs and the tank is 36in long. so the horizontal spread isn't thaaaaat great.
But I had to get 2 (was given them for free actually. lol) to get the correct spreading needed for the depth (front to back) of the tank.

Wouldn't a weekly water change replenish CO2,etc?
