That might be an actual disadvantage to having a bare bottom tank then?If you used aroggonite and if sand was deep enough to create low oxygen, then some denitrification will occur and some passive aroggonite buffering as well as trace mineral addition.
Well i have a high nutrient bare bottom lol. .54ppm po4 and 3ppm no3.It would be a disadvantage to me. I run high nutrient system using sandbed to feed sea apples, flame scallops & sponges.

The last time I measured was 10 years ago.
Nice! Based on the lack of green algae and corraline on the back id say your tank is low nutrient. Maybe its time to measure?
Groundwater isnt usally high in phospahte and nitrate though is it? 900 tds i bet is full of calcium causing those numbers, not high nutrients. You dont own a po4 test or no3 test?At the time the video was made, I hade a cryptic refugium on bottom and a Jaubert Plenum on top. I now have a cryptic refugium with a reverse flow undergravel filter on top and a mud/macro filter on bottom. I assure you, I have a high nutrient system,
Groundwater at 1000’ deep and a tds of > 900ppm goes direct into tanks. Nutrient management is accomplished thru combination of nutrient export of seaweed and nutrient recycling into fish and coral.

I dare you to test it and report backCory,
I have been reefing for 50 years. I have owned those kits. When I need to know numbers, I send sample to lab. It’s been about 6 years since I needed to know numbers.
Taricha I find sand to be that way, agreed in this regard: it’s nitrification abilities are instantly expendable
the system does not become linked to its added surface area and then wean off
