I thought I would mention that on two of my tanks that I used under gravel filters on that were in service for 5 years when I took them out of service to move, I was surprised to find hardly any mulm accumulation below the under gravel filter grates. My gravel vacuum must have been pulling any excess mulm accumulation back up through the grates when I did my gravel vacuuming. When you use a UGF it's best to do only half of the bottom at a time and then do the other half on your next vacuuming (alternating sides) so as not to remove too much at one time to avoid crashing your cycle. They do work great for planted tanks as you mentioned. They probably should not be used on tanks that have fish that like to dig deeply in the gravel and expose the grate(s) because then you could have a bypass situation that renders them somewhat ineffective.
I stopped using heaters in my aquariums years ago because we keep our house in the 70s at all times. My only fish tank that has a heater is the one I keep in my school classroom because it does get cold in there at night and on the weekends.
I am watching yesterday's video today as I clean my tank. I was surprised to hear you read my question. I wasn't expecting that, lol. My last name is pronounced Shimkey (not that it matters but I always laugh when people mangle it). Anyway I wanted to comment about diatomaceous earth. I live in Phoenix and many people use it around their foundations because it slices the bellies of scorpions and kills them. For that reason, I don't think I would ever use it in an aquarium. You know more than I though!

Makes sense👍🏻

I love question answer shows😊
Thank you for stopping by😀👍🏻
Hi, Ben, are you getting this? Tammy. And I knew Jay Wilson, from way back.
How far back? Back to his Security Detail days?

I was surprised to see my comment too.
I totally butchered your name. Sorry. Yes, my wife uses it in the garden to kill pests. I think I'll stick with CaribSea, LOL!
