Aquarium gravel question for gritty mix
For some reason, the search portion on GF's site is not working at times. So, hate to repeat a question, but I know I've read before some postings about aquarium gravel possibly being a sub for gran-i-grit. I know Al kindly answered my inquiry about crushed coral, but upon closer look most of this white gravel I have is smooth and not coral, but a rock of some kind. The size would be perfect.
I thought I found chicken grit, but it was way too small. I have 2 each 5-gallon pails of clean aquarium rocks I found on craigslist, but I cannot identify the rock. But it is not porous, no holes, just really stone-looking. I could sift out the small pieces of bleached coral in there. Would this do? Please help!
