DSB and Big Skimmers?
 

I have always had excellent sps color and growth in my tank with my DSB using a small skimmer (75 gallon with a prizm, yes a prizm) Ever since upgrading tank and skimmer that has gone in the toilet. Is a DSB an efficient enough method of filtration where I don't need a big skimmer for sps? I upgraded to a 120 with an octopus nw200 slightly modded. So I have two theories. One, I screwed up my sand bed when I stirred it all up and transferred it to the new tank. Two, I'm skimming way to much cause my sand bed is already an effective form of filtration. Anyone have any experience or advice?

I don't think a sand bed and a skimmer do much that is similar, so I would not expect that the size or presence of one impacts the need for the other significantly.

So what do you think about my sandbed being fudged?

Yes, it would certainly get messed up when moved and may take a fair time to reestablish.

What is the observed problem with the tank now?

No stony growth. This is ~8 months later, still no results. Nothing else has had any major changes. I added a fuge but can't see that as a bad thing, took care of some minor nuisance algae problems. I obviously upgraded lighting and flow to account fot the larger system, that's it.

Phosphate can slow coral growth, as can reduced alkalinity. Do you monitor those?

What was your flow before and after you switched tanks?
What was your lighting before and after?

Yes, they're both in check and have not changed.

These were appropriately upgraded.
