    Update. 28 months since going skimmer free just water changes, ATS, and 1/2 cup of carbon per week. Tank is doing awesome. I get a slight brown on the sandbed towards the end of the week after siphoning it takes about 3 days for it to show up again, minor nusiance other than that tank has done great.

    Sorry Don't have as nice of camera and they turned out pretty blue but you can at least get an idea.

    5 month update, This coming January 2015 will be the 3 year mark of ATS scrubber as main filtration, no skimmer:

    I unfortunately lost the nice orange hammer coral during our vacation in August, had to replace it with a metalic orange one until I can get a better piece in the spring. I did a little re-arranging to get the LPS grouped more together, that left the other side mostly acans and zoas. Not sure I like it but will see.

    Outside of the orange hammer, no other fish or coral losses. Tank has been doing steller overall. Scrubber does excellent job with my nitrates but the phosphates do start to creep up slowly. For now just add an extra water 40g water change to correct it. Exploring using Lacl3 in a reactor with floss periodically to handle the phosphates, don't plan to use it regularly just when the phosphates start to creep up on the .1 - .12 range when algae/cyano seems to start popping back up. Phosphate levels around .06 - .08 seems to be the sweet spot for my tank combination of decent growth and great colors when kept in that range.

    So here is the fluffy side after rearranging:



    The "Not so Fluffy" side:



    And full tank shot to put it all back in perspective:



    Not sure I'll keep it this way, likely will go back to a more even mix to try to keep it a little more balanced looking. Still fun to tinker.

    Sweet tank! Do you have any pics of your scrubber? Do you still have the packed frag tank too?

    The link in my signature, click on filtration tab for the scrubber pics/details.

    I did repurpose the 5' frag tank, I now use it to house my pond fish in the winter time. Being all glass with lots of surface area just too hard to keep heated in the cool basement during winter the pond fish are fine with room temp water so it's a good fit. 800w of heaters would run 24/7 and still could keep within 2-3 degrees of target with the 5' frag tank + 180g show.

    I went back to just using the 60g sump as the frag tank. It still holds 400-500 frags. Instead of growing out any acros/sps in the frag tank, I'm just going to trim and trade/sell as fresh cut at local club meetings.

    I am in process of attaching a 29g in wall montipora dominant tank that will be tied to this system. Goal is to have it up and running by Thanksgiving. I have to reroute some electrical lines where the little inwall tank will go so that has slowed down the project.

    I recently started using LaCl3 for phosphates. Phosphates are never real bad but slowly over time will creep up to about .1 - .12 and will start getting some cyano here and there and sandbed won't be as clean. I bring it back down around .06 ish with 2mil of LaCl3 diluted in ro/di and slowly added to a 5micron filter to remove the precipitate so it doesn't hurt the fish. Normally when would start to creep up I'd squeeze in an additional 40g water change and that won't be necessary.
