Tahitian Black Moon Sand or Small, Round Pea Gravel?
Hello everyone! I was wondering if Tahitian Black Moon Sand or Small, Round Pea Gravel would be better for my tank?
I am currently cycling a 37 gallon Eclipse tank. I would like to have 5-6 cory cats & possibly a bristlenose pleco. Currently, I have black gravel (not rounded pea gravel, just your standard colored gravel that you purchase at a fish store). I undertsand that this can be a bit sharp for the cory cats. So, I would like to go ahead and make a switch to small, rounded pea gravel or tahitian black moon sand. Which would you recommend?
Additionally, would I be able to "vaccum" sand like I am able to vaccum gravel? Many thanks for your advice! :)
sand looks nice and has more surface area than gravel but it is harder to keep since they can compact over time making anearobic spots. But either ones fine
If you using a ugf, small round gravel is the only way to go. You will restrict water flow with sand. Gravel size should be around 3/16" or 5cm. Sand will also eat up a power filters with extremely high water flow unless a prefilter is used. If you gravel is too small, or you use sand, compaction is a big problem if you don't stir the bottom regularly.
