Flourish Excell is a great addition to smaller tanks but with a large
one you will quickly use your bottleas daily you must dose one capfull
for 55 gal so after about 2 weeks you would need to get a new 220 ml
bottl. You can buy this in 2l and 4l bottles though and that will
help.
Regular flourish is the main fert i use and as long as you start low
and do not overdose you will be fine.
I also suggest iron and potassium.

At BigAl's it mentions that a 250ml bottle will treat 50G for 1-2 months.
So according to them a 2L bottle would last between 8 and 16 months, which
doesn't sound too bad. Btw, what are the dosing instructions on the bottle?
Does it say how many ml to add every day or does it just say "a cap full"?

Thanks,
Harry
