I've only been running my refugium since November (5 months) and it's doing what it needs to do as far as I can tell.
I'm running the DSB & It's not trouble free yet. I do have cyano in my refugium, but it's NEVER matured on the sand bed...only on the acrylic walls and on my chaeto. I've had high phosphate level but I'm getting it down. I'm not worried about if it never gies away completely. It's maturing in the fuge & not in my DT.
A small amount of nitrates is not a bad thing & we can control nitrates with WCs.
The refugium can be your pod growing place & the chaeto can uptake the nutrients from the water.
I'm not seeing that it will become a nitrate trap. No more so than your DT....it's the same as a DT with chaeto instead of fish. A safe place to let your pods reproduce without having to maintain a whole seperate system.
I feel like if my refugium DSB ever gets to be trouble, I can easily take it off-line & remove it. I'm thinking it is more of an good thing & hope I don't have to do that. Time will tell.
