Adding reborn to reef

[Kuloneli]

Hey guys I’m new to r2f. Just wanted to see what y’all thought about SLOWLY siphoning out sand and slowly adding two little fishies reborn as substrate. I’m doing 25 gallon water changes every 2 weeks and want to slowly take sand out and replace with reborn. Planning on taking time and getting it done over a course of 3 months. Currently have a 80 gallon innovated marine sr80 tank that’s been setup for 10 months. Please let me know your opinions.

Replacing sand shouldn’t be an issue if you do it slowly, maybe 20% at a time. But why?
