I recently did a substrate swap in my 125 gallon. WOW was that a chore. I went from fine white play sand to the 20/40 black diamond abrasive media. Throughly rinsed 150lbs. Here’s how it looks before and after
Thanks a lot. It was a lot of work wow. It takes so much substrate to cover this big of a tank lol. 90gallons was my biggest before this one. Rinsing it all was a pain. And yes it took probably a couple of hours. I really like how bdbs looks, I was a little hesitant but after scouring the internet I decided it seemed safe. So far so good.
