LIghting Colours/Timing/Fert Questions

Recommended Posts

Ok so I am running 4x 80W - 60" T5HO bulbs on my 120G planted community Aquarium. It is a well established tank and has been running for approximately 4 years

Lighting timings

8am-12pm on

12pm-4pm off

4pm - 11pm on

11pm-8am off

Plantlife: Amazon Sword, Anubia, Cryptocoryne Wendtii, Rotala, java fern windelov, and a couple of unknowns.

I am struggling a little with algae blooms may adjust light timings to see if this helps.

I'm running the 6700k daylight bulbs

I have been considering playing with my colours a little to do a couple of things....

1) potential to make the reds and blues in my fish colourings "pop"

2) make the greens,browns,reds in the plant life appear more vibrant

3) potentially aid in plant growth etc

Are there any recommendations on lighting colour that will do this?

I have been looking into the Aquaflora bulbs? Does anyone have any experience/results with these?

what (if anything) would a pink or purple light colour do for a planted tank? as I have read that these colourings will aide in making fish colours more vibrant?

Would I have to alter my timings excessively if I were to start messing with lighting colours?

also if anyone has any advice on somewhere in Edmonton where I could find 60" bulbs for a reasonable price that would be awesome!

Most "daylight" bulbs have spikes in the blue and red spectrums, which are great for photosynthesis.  If you can get the color spectrum for a given bulb, and see that it has a bit of both of those colors, then you're good to go for growing plants.  If you're running multiple bulbs, then put your "fish color" bulbs closer to the front.
