You must have misunderstood. We've never used cables smaller than 100 watts in
any of our tanks. Our original 90 gallon tank had the 250 watt cables which were
physically too long. Our 100 gallon discus tank had 100 watt cables which
didn't seem to have enough oomph.
A 150w cable for a 90 gallon tank sounds reasonable.
On the Dupla website, the following cables are available:
Duplaflex 75 - 30 watts
" 200 - 60 watts
" 300 - 100 watts (276" long)
" 500 - 150 watts
" 750 - 200 watts (512" long)
" 1000 - 250 watts (669" long)

Check with Monolith Marine Monsters - they have a range of heating cables
available.
