petsmart had a big sale on 50# bags or Caribsea Torpedo Beach so bought a couple bags to try. I will get that rinsed, figure out how to get gravel out and sand in without killing fish, then maybe think about easy plants that work with my lighting/setup that don’t require much trimming and CO22tank, I forgot to address your concerns on pool filter sand & bottom dwellers. I've used it with several (10?) species of loaches & some catfish without issues, no barbel wear or body scratches. Only 1 actually buried itself entirely in the sand ( finer #1 pfs), most just poked their faces in for live worms etc.
I would be more concerned with sand sifters & PFS like some cichlids. But...if it's too big or rough they don't spew it out their gills, they just chew & spit IME. I don't know other than angels (not that I'd them call sifters), what cichlids or other sifters I've kept on PFS. Smallish gravel, yes, but then no gill action, just spitting.
#1 pfs does tend to "blow around" more than #2 or 20 grit depending on the filter return strength. & since it's lighter it's harder to swirl'n'vac over the surface or the quick vac plunge without losing more sand. You can always rinse any in the bucket & pour it back in the tank, there's a steeper learning curve with finer sands.
I only tried play sand once & hated it. It wasn't graded so there were fine & larger grains with compaction. Mine was also very dirty even after rinsing several times. The type 2 tank uses is more uniform & I'm sure much cleaner but at a huge cost difference, mine was ~$3/50 lbs.
I think I must have gotten Eco Complete (not sand) back in the sale days & free shipping of Drs. Foster & Smith (Live Aquaria now, owned by Petco) when 2tank got his Torpedo Beach sand, lol. I still have it & like it's small gravel size & almost black color. I tried Flourite black sand once but it was too fine & dusty for any but my 10g shrimp tank. My cherry shrimp did look great on it & plants grew very well. I was given some regular brown Flourite I tried once. It seemed more sharp than Eco, meh. I also have a newer tank with Black Diamond Blasting sand, no fish yet just plants & algae...I'll see how it works out...
I that may be my sum total of sand experience, sorry to ramble on...
I have a very small grained natural gravel in one of my tanks. On my ~10y/old oscar tank I have a mix of black and natural gravel and on my 9yr old planted 55, it's black gravel that has (or had?) specs of colored gravel in it at one time.Is there a smaller gravel that wouldn’t do that? My black gravel is starting to chip and would like something smaller/lighter to brighten tank up but don’t want anything sucking into my filter. And like I said wouldn’t mind some easy plants.
I’m in the “trying to find new decor” stage now lol.I have a very small grained natural gravel in one of my tanks. On my ~10y/old oscar tank I have a mix of black and natural gravel and on my 9yr old planted 55, it's black gravel that has (or had?) specs of colored gravel in it at one time.
Like you say, with most canisters, sand shouldn't contact the impeller because the impeller is at the top, after the water goes through all the media.
Here's some pics of my tanks from the other day.
