All,
Yet again I am on the hunt for some advise. I have had a 180G tank now for 5 weeks [gift from my next door neighbour] and it currently contains 3 x 8" Oscars, 1 x 12" Plec, 4 x 6" Silver Dollars and a large population of breeding Malawi Cichlids, havent a clue what species.

Filtration is by 2 x Rena XP3 canisters. Sand Substrate, 4 air hoses, 2 heaters. Silk plants.

My question today relates to lighting, at present there are two lighting power boxes one of which has a white tube attached and one has a blue tube. I am wanting to replace both as they are rather old and was wanting some advise as to what to replace them with i.e tube lenght, colour, wattage and whether or not I need to power units or ust purchase new tubes.

The lighting aspect of the tank is the one thing which totally confuses me yet If i sort my lighting situation out with the correct option the tank will look amazing.

Look forward to any advise you may have.

Cheers

Ross

What are the measurements for your tank? No ambition to have plants, right?

Apologies...

Tank dimensions are 6ft x 2ft x 2ft.

Not planning on having any live plants.

Cheers

How long are the tubes that are in now and do you have a canopy or light strips sitting on glass??

72" fixtures can be expensive and only made by a few companies. You could just get 2-36" 2-tube fixtures and I think you'd be happy. You may even find a 3 or 4 tube that will work just as well. Since you don't plan on plants, you won't need all that much.
