sps turning green. help
So i have noticed that most of my spa corals are going to the green side of color.
Any thoughts? Ca 430 Alk 8.5 Nitrates 10 PH 8.2 Phosphate .03 Mag 1250 I have led light its a Chinese deal. It would appear that the blue spa has the most noticeable change to green. |
What LED Light from China do you have? Is it full spectrum? How do you get your water? Nitrates could be a little lower.
|
Shifts to green colour can becaused by a number of things, you're lighting being one of them. If you are coming up empty handed there, look into the iron concentration in your water (there might be something rusting in the tank). Increased iron levels cause green shifts in coloration, particularly for SPS.
|
Some of mine turn green when the nutrients start to rise
|
Not sure if they are full spectrum. It says they are Cree LEDs on the unit but.... The water is ro di and tds meter says 0 or 1
I will get an iron test and check that. What are your thoughts about adding a couple t5 ho bulbs and would you. Go actinic and white or both actinic? |
How long have you had these corals under this light? What colour are these corals?
|
Could be Iron content in your water ... :noidea:
Some of my corals started to shade towards the greener side after I switched to a supposed HiCap GFO which is brown, rather than the BRS HiCap stuff which is black |
Corals have been in tank anywhere from6weeks to 12weeks . I just started into the spa workld about four months ago.
Corals are blue,purples mad a yellow one. |
