I know everybody has strongly differing opinions on lighting (wpg, intensity, etc...), but 130 watts of pc will be more than enough lighting, and 150 watts of halide over an ~18 gallon tank that you want to feature "a lot of anubias nana 'petite'
" is on the extreme
end of overkill -- 8.3 wpg!!! You'd be walking a tightrope to avoid an algae filled cesspool
If you want intense light, a 70W halide will do the job nicely and if you want managable, even light a 2 (or 4 bulb for more flexibility, burst options) HO T5 system would be ideal.
Just my 2¢
Looking forward to seeing this running!
