(10gallon water change earlier, waiting couple hours before I test the water)
(Update) I think my alk kept swinging lower because of the multiple water changes I've been doing for the past couple weeks. I need to slowly get it back up to 8.5dKh.
I am not sure about the magnesium. I didn't think I dose as much. I think I need a new magnesium test. I also took samples for ICP. Hopefully it can match my tests.
Big changes today.
I rearranged my sump. (Forgot to take before pic)
Swapped chambers around. Now its refugium then skimmer chambers.
I also swapped filter socks with filter cups. I don't use filter floss for now. I can always either put socks back or just get floss.
I put marine balls on it because the cups are not fit perfectly on the hole. Kinda a bit too small. Kinda miffed about it. I think I am going to put rubber around the top.
I want to see if I can get the nitrate and phosphate up.
I have turned down my refugium lights down to 6 hours nightly and even took off my skimmer 12hours daily.
So I will have to test nitrate and phosphate for the next couple days.
So hopefully without the filter socks, I can turn on my skimmer all the time. I think my skimmer helps with the ph cause I have the airline getting outside air.
I also increase the sump water level a bit and lower my return pump power(from 65 to 55).
I also noticed that since the refugium light is pointing the socks chamber. The light spill to the back of the tanks is dimmer. So thats good. The possible issue is algae on the return and socks chamber. Coralline would be fine.. different kind would be ....
