How to tell the difference?
On my 100g planted tank, full EI dosing currently, only 2 rows of T8's are on (so only 120W total T8 lighting). CO2 is cranking through.
No significant algae (except brown diatoms, I presume due to tank still maturing). Plants are growing very very slowly though. New healthy growth is evident at the tips of stems, but it is so so slow.
So is this a CO2 limitation or do I need to add a bit more light? How do I tell which is the limiting factor?
The T8's are about 18 months old now, but I'm sure Tom once said to run 'em till they drop....
Thoughts?
