| Re: new here Pool filter sand is inert--it doesn't give the plants anything except weight to hold them in place. Until PFS collects a year's worth of mulm, the tank will need atificial fertilzers.
Pool filter sand is pretty fine, so it can compact and form anaerobic pockets. It is not as bad as play sand, but you will need to avoid a depth greater than +/- 1.5".
If you want to use an inert substrate, I think normal aquarium gravel would be better. |
