Thanks for that, so i have worked out my tank gets 0.90wpg - no wonder my plants dont grow much.
We are upgrading soon to have CO2 and upgrading the gravel to JBL Aquabasis plus and black roman gravel.
Presumably i need to upgrade my lights now, shame i didnt realise as i have last week replaced my 2 x t8's.
What kind of lighting should i look for?, i would much rather keep the lighting under the hood as it is now so would switching to t5's make much difference or as im going to upgrade is it worth looking at something else?
Thanks again for any help
