im running a small nano tank with built in 2 No. 24" T8 tubes  1 ZooMed Reef Sun 50:50 / 1 6500k Daylight bulb & some moon light blue led's.

I am looking to get some coral pop but to be honest i dont really like the Blue light. the tank originally came with 2 6500k Daylight bulbs which to be honest i like the warm colour that these bulbs give the tank but you dont get to see any of the fluro of the corals. so i purchased a Zoo Med Reef Sun 50/50 24in (18W) RL-24 | Aquatic Products | Online Reptile Shop

this has helped a little although i think i was expecting more. now if i fit a second reef sun 50:50 light will this increase the pop of the corals or do i just need to buy a marine blue bulb :(

or are there any other options that i might be able to retro fit into my tank canopy??

open to suggestions

Don't know what power your other bulb is, but the link you posted for the 24" version is only 17W.  Assuming the other bulb is the same, that's a total of 34W over what area/volume?  What size is your tank?

For arguments sake, lets say 24"x18"x24" (guess from a pic you put on about the trickle filter), that's 45 US gallons.  The rule of thumb for anything other than LEDs is 4W/Gallon for low light corals, and 10W/Gallon for high light requirement corals.  That's assuming it's not a deep tank.

You have 34W/45Gallons = 0.75W/Gallon

You need to upgrade to T5s as a minimum, and need to fit in 180W minimum, ideally 450W.  Better would be to go with LEDs, as they work out way cheaper over time.

The original bulbs are 25w. The tank has a total of 44w at the moment. So probably 1w per gallon. Think I'm going to struggle to get 4w per gallon with only 2 light fittings

Sounds like it.  You can't sustain corals in that case.  They will just waste away.  Fish, shrimp, crabs, snails all fine though.  No anemones, as they need a lot of light.

think i may upgrade to t5 bulbs with a ballast change as the tanks only 30 gallons (after a quick remeasure) therefore at the moment im getting 1.5w / gallon.


so an upgrade to t5 should provide enough light

just another thought i know t5 wont really work with t8 fittings due to the ballast needing to be changed to give extra wattage needed.


But  t5 led tubes could be fitted possible to the T8 fittings as they generally require less power..... and due to the strange fittings on this tank i dont need to worry about the tube diameter as its only the pins that go into a fitting and you then turn them to make it water tight.

Have a look at iQuatics (they are a supplier on here - @iQuatics-Online ).  I'm sure Sean could give some advice, and maybe do you a deal.
