We show alternate views plus data on about a hundred or more sandbeds all in one thread going on six years. Am comfortable stating there is zero, zero benefit from not pre rinsing. I opened with ten non rinsers linked for review using the recommended non pre rinse
it was rough for them, following the common advice (and bag directions lol) not to rinse but to add the flocculant and accept the silting.
I don’t know of any other sandbed studies using actual tanks for this long to establish a tenet. can't wait to see them if there are some regarding any test for repeating claims about sandbed outcomes
What it takes to attain complete tank compliance from a group should be represented, the advice to not rinse usually comes from someone who didn't rinse and things did turn out ok. doesn't work large scale though
We claim that natural sloughing of bacteria and storm recreation type cleaning are not sterilizing moves, that way context can remain accurate. by removing a top layer of bacteria, a bioslick of more bac is still underneath, specifically. We expect washing hands to remove bacteria agreed, the top portion
When you do a water change, you remove bac, did they matter? Nitrifiers are 1000% in the water, they're attached to the floc we call marine snow that all tanks have. by being attached to the massive surface area in the sand and on rock surface area, they're in numbers sufficient to induce ammonia removal and rinsing won't change that measure.
We show how all reefs can have the sandbed removed instantly, without ramp up, and the rock takes over= Sandbed bac don’t matter, they're redundant in the system and actually an oxygen tax.
To be specific, your sand passes an oxidation test for ammonia before and after a rinse. Silt is unhelpful
Don’t pre rinse tbs live sand, the kind with real live animals you can see in it wiggling.
hold up a clutch of that ocean direct=silt + really good sand. the case is totally closed on pre rinse vs no pre rinse. I could not locate any source nor article showing the benefits of mass silting if a powerhead falls or some access is required to guide out cyano etc, but that thread above showing the opposite stays active.
