Changing from Sand to Fluorite
Okay, so, newb here. Lemme start with that I have a 20 gallon tank that's been running for about three years now. I started with gravel and changed to sand about a year in or so and that's what's still in there now, a white sand. I don't mind the sand, except that it kills my filters and I'm considering a fish that likes to kick up substrate.
So I've been eyeing fluorite, it looks a little heavier than sand and if that's the case then I'm hoping it won't get sucked into the filter so easily. My problem is how do I switch from sand to fluorite? With the initial change to sand I put a bunch of gravel into a nylon and let it hang in the tank for a few weeks, the transition was smooth and no fish were lost.
But sand would fall through the nylon, wouldn't it? So how do I switch from it to fluorite while keeping the beneficial bacteria?
Any suggestions? Thoughts? Comments?
