We work in full increments in the sand rinse thread, no partial actions because that upwells nutrients left over from the unrinsed portions. My system has you make both your rocks and sand cloudless, then you apply the modeled kill step
I recommend no blending of actions, use the water tuning way first with no peroxide or tank cleaning. If their way doesn't work, when we run my method it will work, but you have to be done with the other method before running mine as we make polar opposite recommendations on what you should do with detritus. My system will work when you are cloud free, and it takes specific ordered steps to get there. Zip me a message if the other ways don't pan out and this tank can be put back into complicance easily. If you are going to use peroxide in any way without de clouding the system, my way isn't ready to be applied yet, we clean the whole thing out all at once and this requires a huge amnt of trust in the approach. we usually only get that much resolve right before someone is about to take the tank down, before then they'll try every partial action possible to avoid the work and perceived risk of the rip clean though it's documented really well
