More progress on lighting.
Got those blue LEDs (430nm I believe) and thought I try them to see if I get some nice corals phosphorescence all over the tank for a couple of hours after the actinic go off… Must admit that soldering is not my thing and it gave me a total new understanding of what kind of undertaking people take when they decide to DIY LED fixtures all over their tanks.
Also installed endcaps for T5s. will have 4 rows of T5s 2 in the front and two in the back. Each row will take 2x54W T5s except Row 3 which will take 1x80W.
Also added this small support in the middle of the fixture where Iw as getting some bowing which solved it.
Peeled the Blue covers from the Lumenbrights and the reflectivity of the material used is amazing.
Installed 3 250W 20K Used Arcadia bulbs which will make it easier to light acclimate my corals which are used to much less lighting and will switch to new Bulbs in a couple of months.
Installed the light rack again, Lights are with the bulb at 21” above water level which is the recommended height
Finally got light!!!
Very impressed by the new reflectors and the coverage I’m getting. I was worried that the coverage will be too narrow and that I would struggle with shadows but I’m getting very good coverage that I’m considering experimenting with lowering the lights for higher PAR
Must admit that I’m liking the looks of 20K bulbs, been using 10K the last couple of years for more growth…
Currently finalizing choice of T5s most probably it’ll be Gieseman as it’s locally available, was advised to use from front to back
Actinics pure
Actinic +
Aquablue +
Actinic +
But then I wasn’t aware that aquapink is available so might switch to
Actinics Pure 2x54W
Actinics Plus 2x54W
Aquapink 1x80W
Aquablue+ 2x54W
Still open to suggestions before I order.
