I've read that post also and it has some great info. Very helpful.
In the cannister filter there are some foam blocks in the pre-filter. I rinse these in used tank water when I do water changes but I'll start rinsing them out every day. All 3 trays are filled with carbon, not the granulated kind, but what looks like Kent Reef Carbon (little "sticks"). Also, I just discovered a bag of this carbon in the supplies in the cabinet. I need to start changing out the carbon as I don't know how old the stuff is that's in the filter. I'll change out 1 tray at a time since there is probably BB established in there.
Also, I added some snails and a Peppermint shrimp a couple weeks ago. The Turbo snails (Trochus) are amazing and have done an awesome job of cleaning up the rocks which were covered in brown algae. I have 2 Turbo snails, 2 Bumblebee snails and 1 Peppermint shrimp. Is this ok for a CUC?
Eventually I want to get some more live rock. I would also like a protein skimmer in place of the cannister filter but finances right now are really tight. Will the cannister filled with carbon be ok for such a small tank for now?
Pasfur, I saw your post about that deal on the protein skimmer for small tanks. I wonder how long that sale will go for. With X-mas coming up and the fact that I have recently seperated from my husband it will be awhile before I can budget it in.
Thanks for all your helpful suggestions guys!
