Your 1" sandbed will not promote nitrates but it deff won't make them better. More neutral It's just a sandbed at that point.

I have a carpet anemone so need at least 4” Now since we are mostly trying to mimic ocean conditions has anyone ever layered the sand like 40% coarse crushed coral ,40% special grade and 20% sugar...

Jan 3, 2020 · Although I see the safety factor by employing a remote deep sand bed but can a five gallon bucket really provide enough surface area for significant denitrification? My current tank the 70 gallon runs mostly on micro with nitrates at 2 and phos at 0.8.

Dec 5, 2024 · Starting my tank in the next month. Last tank I had 10 years or so ago, I ran with a deep sand bed and had very little concern with nitrates. It was a 40 gal with sump. This time I'm running a 75 gal with a sump. So what's the consensus on deep sand beds these days?

Aug 11, 2020 · My sand bed is about 4-5" deep in the fuge. It is full of black metal deposits. I accidentally dropped a rock that had previously been buried in the sand for the last 5 years and it made a huge brown mess in both the tank and the fuge.

Jan 11, 2022 · Almost 20 years ago, when I was first going to start a reef tank, my plan was to do a deep sand bed. I loved the idea that deep sand beds (without sand sifting creatures) were an integrated part of the reef ecosystem. It appeared that there were a lot of people who had them for years and years...

Dec 17, 2019 · The macro will grow and actually act a detritus trap. There is nothing that can be done about that, but adding sand or rock to a refugium compounds that issue. The filtering benefits to a deep sand bed in a refugium won't be enough …

Dec 8, 2017 · When I was dabbling in this hobby sometime about 2003 or so, I remember some reefers on the old RC were trying out Deep Sand Beds (DSB's) 6" deep or greater, or more specifically of interest for me, a Remote Deep Sand Bed (RDSB) for nitrate reduction.
