Default Re: Accelerate crossing back rings (6th level rings)

Prof JD, I am wondering if I could use Bio ring as gravel ? Fill the bottom of AQ with a lot of Bio/ceramic Rings. ceramic Rings won't raise my pH & gH so I can maintain the water pH at lower end (6-6.7).
I was having a hardtime to find the right stone for gravel.


can I do that ?

thanks
