Hi Jorge,
Long time no hear.
How are your GTA frags doing?
I lost all the one's we bought at the roughly the same time as you did.
I now know why. I got busy, and move my doser to other tank. From what I see happening now my Alk is dropping incredibly fast. Approx 0.2 dkH a day. And my Calcium is also dropping.
This happened to me last time, but I never paid attention, so Alk dropped below 6, and I topped up too fast (few times). Very bad.
But I am prepared now with a new Doser.
I actually finished adding new feature (Micro Calibration). I learned with playing that my Kamoer pump are very accurate. I now can dose BY THE DROP.
Anyway to answer your lighting question.
It is important to give all the LIGHTING information.
HEIGHT: All Lights are 13 " above Water Surface (except 1 T5)
DEPTH Most Acros are around 8" below surface of water. (21" Tank Depth)
LIGHTING
->
2x 175 MH (14000k Phoenix Bulbs) [Ballast is selectable 150,175,250,HQI]
->
2x T5 (1xBlue Plus, 1xCoral Plus)
->
1x LED Home Made Fixture (15 Cree LEDS, Blue/White @ 40% Max Setting)
PHOTO PERIOD
-> MH(175W) (
6 Hours)
-> T5 (ON/OFF 3 Times when MH off) (
5 Hours Total)
-> LED (Ramp UP/DOWN 0%-45%-0%) (
Approx 12 hours)
I do plan on lowering lights down to 10inch, but I like higher since it spread the light more evenly between the two MH Bulbs.
The LED fixture I put in between the MH lights as a filler.
Maybe this Picture is better than my explanation.
