So after much research on this and other sites I finally decided to try a ATS to see about reducing the phosphates and nitrates in the tank while getting the unsightly HA out of the display. Thanks Santa Monica for the advise and info as I decided to try to replicate the SM100 you posted on here. All I have left is some more painting to reduce light loss outside of the ATS, drill the drains and plumb it into the system which I am hoping to have done next weekend. Not happy with the screen though so I am thinking of making another especially since there are now new recommendations to the size of screen needed based on feedings. ATS was water tested overnight and no leaks. Here is what I have so far and would love feedback on this since I am new to ATS and never tried one before.
