So far so good with all the hitchhikers on my live rock! And with my B-E-A-Utiful Feather duster! But can feather dusters split into 2 like mushrooms? Im not sure if it really is 2 but it kinda looks like it is...hmmmmmmmm...??? Well anyways it still is beautiful and i love it! Can't wait to get my clowns in a month not sure if i will get any fish before then. As soon as i get money hopefully before i get my clowns i am going to get a PH test kit, Nitrate test kit, and a Calcium test kit. Should that be good as far as test kits because i will have a Salinity (Hydrometer),Ammonia,Nitrite,Nitrate,Calcium,PH. Is that good?
