I started myself a new small FOWLR aquarium and it finished cycling about 2-4 weeks ago. I'm unsure of the origin of the live rock I went through the cycle with (I don't know if it started dry before the shop sold it as live) so I got some fresh live rock right out of the ocean to double the total amount of live rock in the tank...There's some absolutely beautiful coralline algae on the freshly collected rock! Anyway, I put it right in the tank and since it was covered in sediment when collected it's making my water a little murky. Since it's a small tank, I was planning on only doing water changes but now I'm considering adding a canister filter to filter out some of that sediment that's now free in the water and re-settling on the rocks after I brushed them off with a toothbrush. The canister filter I'm considering comes with or without a UV sterilizer light inside...which should I get? I don't want to kill the beneficial bacteria but I've heard UV can be really helpful in managing parasites I may get later or may have picked up on the live rock...What do you guys suggest?
