Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
Would need a pic. of the things on your rock to ID them.
You can run either carbon or phosban in your reactor.
Carbon will help purify the water.
Phosban will help keep your phophates(SP?)down.
Once you have figured out what type of fish you'd like, don't add them all at once. Put the least aggressive fish first, and the most aggressive one last. (Even though I'd highly recommend against getting any type of even remotely aggressive fish for your system).
Anyone considering a Banggai Cardinal should be sure to ONLY ACCEPT CAPTIVE BRED specimens. They are being depleted from their natural habitat through over-harvesting and poor collection techniques (cyanide) that cause the subsquent death of most of the ones that are imported.
Please tell your fish store to only bring in captive bred Banggais. The hobby is solely responsible for them being on the verge of extinction in the next 10 years if something isn't done to stop it.
