Hey guys so I'm getting in 15 columbian tetras tommorow and 7x 2.5-3.5 inch red head geos on Thursday. My 75 gallon has 2 aquaclear 110s and was well established with fish that were removed monday. So basically this tank wont have fish in it for 2 days before the columbians will be added and 3 days until the geos are added. How depletes do you think the BB will get in that time frame. I'm guessing it should be fine and adding seachem stability this week will help but was wondering if I should keep an eye out for a mini cycle or anything else in that short time frame

If filters are running I'm assuming you will be fine probably still enough ammonia left in water from previous fish to keep bacteria feeding until Columbian Tetras are added. You may or may not have a mini cycle but still test parameters.

That's what I was thinking since filters have been running and the sand should have bb as well.

Do you have chloramine in your water? If so, do a water change everyday (using water conditionaer) and the ammonia from the chloramine will keep the bacteria fed

Most likely my tap water does I'm not quite sure about the amount of chloramine or amount of ammonia in the chloramine since I usually just age water in a barrel with an air stone to release gases and add prime.

But when all the old fish in the tank were removed yesterday I did drain the tank down to net them and did a 65% water change and also added prime and stability.

Today I added my 6-7 inch blue phantom pleco and stability

Take an ammonia test of your tap water. Or read your water quality report from your local water authority. The information will be there.
