I have a 90 gallon, same dimensions, and I only use 4 NO flourescents (2
Philips Agro-lites and 2 Philips colortone 50's). I have about 14 species
of plants (5 Echinodorus spp., 2 Aponogeton spp., 1 Sagittaria spp, 3
Cryptocoryne spp, Nymphaea lotus, Bacopa caroliniana, and Hygrophila
difformis). They start to bubble O2 within 2 hours of the lights turning
on, and if rapid growth, blooms, runners and new red leaves on the
Echinodorus are any indication then the amount of light they receive is
I shoud also point out I add PMDD, CO2, and have a 4" loamy substrate.
I do believe 10 tubes would be overkill, and 8 may be unnecessary,
depending on the types of plants you wish to grow. If your plant list is
similar to mine, then 4 or 6 tubes will do the job. How about if you start
with 6, and design your hood to add more later, if necessary?
