The lighting on the aquarium is going to be upgraded from 1×55 watt power compact and a 14 watt regular globe, to a setup with 4 x 55 watt power compact globes. This will be achieved with 3 light fixtures, 1 double fixture which will run down one of the edges of the tank, and then a single globe fixture down the other side and the other single fixture in the front of the hood. The double will be over the area where predominately the ground cover plants will be, while the single will run along the edge where the taller plants will grow.
Two things need to be modified in the tank to take this configuration. First the hood needs to be modified to allow the two fixtures running along the sides to fit. The second modification is needed for the light mounted in the front of the tank. This is the main access to the tank and therefore needs to be easily removable for feeding etc. At this stage I am hoping to attach the light to the hood at the front. I will also need to make the switch easily accessible so that I can switch the light off before opening the hood.
The lights I am using are all Aqualina Power Compact hoods. They seems to be reasonable quallity hoods available in Australia at a reasonable price. I will initially setup the lighting without changing the substrate or CO2 injection. Worst case if I get an algae bloom I will simply turn off a couple of the lights.
Here is a photo of the first stage of the lighting complete. I am waiting for the glue on the hood to dry after a couple of modifications. The light along the front hasn’t been put in place, so the front is a little dark.
