Stef Posted June 19, 2021 Share Posted June 19, 2021 Want to pick your brains. I’m upgrading my 3rd and final 3 gal betta tank to a 10 gal. The 3 gal is planted with black sand (Imagitarium) and has been running for close to a year. The new 10 gal will have Seachem Flourite black. My thought was to use the old sand with good bacteria as the first layer and then add the new flourite on the top. Thinking this would ease new tank syndrome. Will the sand eventually creep upwards or interfere with the flourite’s benefits? My plants do well in the other 10 gals on just the flourite. I also have a spare sponge filter running in another tank getting it ready for the new tank. Thoughts? 1 Link to comment Share on other sites More sharing options...

Should work visually. Link to comment Share on other sites More sharing options...
Samanthabea Posted June 20, 2021 Share Posted June 20, 2021 Not sure if it is true but my bagged live sand instructions say to mix new substrate slowly with old over a few days Link to comment Share on other sites More sharing options...
