Is that an ATI Sunpower dimmable light unit you have?
Yes
Do you find the dimmer useful in plant growing or is it more for a more natural morning/evening transition to/from full lighting. Ive been looking at the non dimmable option and am interested as to your thoughts on the usefulness of the dimmer. What sort of bulbs are you using also?
The wood hardscaping is fantastic and its nice to also see a more formally planted scape amidst so many more 'nature' orientated tanks on the forum.
Cheerio,
Ady.
I'm not sure that the dimmer adds any real difference in growth vs not...........but..........the CO2 takes about 20-40 minutes to ramp up........and the light follows this same vector. The CO2 goes off about 20 minutes before the lights are 100% off. Same thing there.
Unlike a manual dimmer, this will automatically slow and progressively dim/brighten any of the 2 channels, this makes the unit much more useful. The controller is rather easy once you figure it out initially.
I have a host of bulb brands and color types, I'm still experimenting with color combos. There is a reflectance aspect to this also, since I view the bulb reflection off the water itself. The colors reflect and make the leaves look different also. Red plant bulbs will make the leaves look more red. Too much red and the tank looks freaky. Too little, not much red color. Same with the Blue(real nice for fish though), purple/violet, various white bubs, Green bulbs and daylight and mixes of these.
Coralife colormax
ATI blue special/purple
URI Red Sun(Extremely red)
Wavepoint: reef sun, daylight, purple
Ge starcoat (Nice crisper midday bul, 6500K
Zoo med plant and then their 10,000K type of bulb
Giesemann powerchrome midday and then the aquafloras
SPS daylight
Spectralux green, daylight and red
There's a few others I have, but those are the main bulbs.
Dimmers are okay where you CANNOT raise or lower the hood to reduce or increase intensity.
Another good reason/application: You want the same spread of light, just not all that intensity.
Example: this tank above is over 75cm front to back depth..........you'd need either a light with lots of bulbs or two separate fixtures. Well, say your goal is a lower intensity, but you want low light over a wide region? Or perhaps you want the color choices with mixing 4-8 different bulbs vs say 2.
Hummph, I guess there are a lot more uses for manual dimmers than I though, but those same things can be done with the dim controller. The dim controller really makes the light much nicer than anything in the USA markets for aquariums.
