I have a 4 feetX18inchX18inch normal 4 feet tank. Currently lighting is using 1 40 watt actinic blue fluorescent and 3 40 watt white fluorescents. All using reflectors.

The hood is custom made of acrylic. Using Elibriu(not sure of spelling) electronic ballast (36w-40w). Each ballast can support 2 40 watt fluorescent tubes.

My question is this. I am intending to save up (I am only a student) by scrimping $$ on food,etc :off: and use the $$ to replace my fluorescent tubes with T5. However, I have heard that a 4 feet T5 light is 54 watts. I would like to know if it would be more cost effective to replace my electronic ballasts with those of higher capacity and get the 4 feet T5s or to use 3 feet T5s instead.

As for lighting efficiency, as my tank is only 18 inches wide and 18 inches deep(including sand depth), How many T5s would I need to keep most soft and hard corals? I am not intending to keep sps and clams? I'm too poor to afford those for now.

Any suggestions would be welcome. This forum is addictive! It replaced my obsession with counterstrike..thank goodness. :rolleyes:

Get the 4' T5 tubes. You won't regret after seeing the light output but maybe only after you see the bill.

Four will do nice.

I'm only 21 lah..Somemore my tank is not using a chiller.

Water depth only about 15inches. Won't MH like cook everything in the water? :shock:

For T5 i planning to DIY...not buying the ready made ones..those 'chop' people one. Oh well..looks like I will have to change the ballast too.

Who want to reserve my second hand Electronic 36-40watts ballasts? :idea:
