Hopefully BRS will change their advice that turns out total clouding for days, but probably not. One of the big let downs in our collection of examples was the one where after waiting for clarity to kick in, they scaped their tank and then the powerhead dislodged and re kicked up the mess for days and days in a stocked reef. Had they simply pre rinsed, it would have never happened. There is no setting in which skipping pre rinse is wise or better, but agreed most do it this way without rinsing. Finding examples of those who wish they pre rinsed is still easy though.
guess what has zero examples: someone who pre rinsed, has a cloudless tank, and regrets that. Redo this reef above, the right way, start with total command vs hesitation. That transfers into so many other proactive reef behaviors that can save your reef one day vs passively watching it die/lose/scale back. Pre rinsing is typically the first assertive / non fearful thing an aquarist does.
Conversely, skipping the rinse out of fear of bacterial loss, when zero proof exists for that claim, starts the aquarist off on the wrong foot and hesitations pop up in several ways along the life of the tank, an example is the fear of cycle being stuck when api shows .25
the first fear of bacterial loss makes the reefer less able to keep the tank alive, that concern trickles to everything from cycling to invasion control, ironic consequence. to begin with total resolve over known outcomes from an action taken makes the aquarists far more in control of the setup, we show.
BRS is turning out weaker reefs with their advice.
