I have currently been into SPS for the past few months and was wondering what is everyone aiming to keep their alk swings at? Mine currently fluctuate upwards of .3 dkh per day and my SPS seem to be doing fine. What is the max some of you have seen without any effect?
I currently run 2-part with the Neptune Systems DOS and love it. You can dose as little as 0.1ml at a time so spreading the dosing across the day is easy.
I have these on an XR30 Pro and love the way they look. Not only does it offer better blending, but it makes the light look more finished. Like previous posters, you can just bump the intensity to make up for the lost par. Im currently running mine at 37% over a 20g mixed Reef thats 13in deep.
I used to use this water prior to getting an RO/DI unit and it seemed to work perfect for me. I have noticed less algae after switching to RO/DI but it is an option for short term.
