Doppler, thanks for the input, while I can get the phyto I do not have the rotifers.
I also cannot tell if there are any sandbed critters, or how many are in there. I have a Mandarine, and a sandshifting starfish, in a 29 gallon (yes I know it is too small for a mandarine) so I wanted to replenish the tank for the Mandarine.
I bought cyclopeze to feed the fish, hopefully it is eating that.
I checked the ipsf websight, and it looks good.
Thanks for the input.
