Sand types and Corys
Hi there, just about to set up the 42 gallon that was sitting wasted in my parents loft (the horror!)
I plan on a planted tank with a sand substrate (with a general amazon-ish theme)
My question is (and I'm sorry if this is a repetitive question on the forum) will pool filter sand be to sharp for the Corys on my fish wishlist - should I use play sand instead (will this compact too much for plants roots to spread/create anaerobic pockets/show up fish waste so I constantly feel the need to vacuum it etc?) or should I just pay out for actual aquarium sand from my LFS (ouch)
Thanks in advance
People use both, I use playsand myself. With any sand, just feel it and see if it feels smooth, or rough.
Playsand will not have compaction issues, but you also generally don't have a very deep substrate with sand. 1-1.5" at most.
Check my profile to see a pic of my pfs. Check the size before buying. Mine is labeled "Coarse Filter" which is of corse too coarse for Cory Cats. The finer ones can work. Clean it well as Corys as sensative.

Given what another member mentioned in an on-going thread on sand, I would caution against using pool filter sand with corys. Here's the link to that thread:

I use playsand, the Quikrete Play Sand from Home Depot or Lowe's. In appearance it is near-identical to the sand in most Amazonian streams, so authentic. Plants grow very well in it. In over 2 years of sand in now 5 of my tanks, I've had no issues. I keep it between 1.5 to 2 inches in most tanks, around 2.5 to 3 inches in my 115g. Photos are under "Aquariums" tab under my name at the left.
I have never seen detritus on my sand; perhaps because I have small fish in all my tanks. I do see it in my one tank with black gravel. Buit my corys love this sand.
And, welcome to Tropical Fish Keeping forum. Nice to have you join us.:wave:
Thanks for the info and the welcome :)
Think I'll go for the play sand in that case - I had half read the other thread regarding the possible issues with PFS and Corys but wasn't aware of a definite conclusion so thank you for clarifying! I wouldn't be able to check the coarseness of PFS in any case as I've never seen it in shops (wet old england in winter is a little lacking in the pool department!)
I have a couple of Pepper Corys in my tank with pool filter sand and they seem to be doing well.
Here is a shot of my playsand after a good rinsing. Interesting to see what is all in there. I expect that PFS would be far more homogenous in it's makeup than this... in fact I attached two more pics, one of 10 year old PFS (cleaned) and one of new PFS.
This are just with my phone camera, the PFS shots are someone else's.
