I just wanted to tell everyone about the great products and great customer service offered by www.ipsf.com from Gerald Heslinga. Twice now I was not exactly sure what to order. I sent him an email describing my setup and what I thought I should order. He then replies with much information and how he thinks the order should be revised to get the best value. Both times his revisions actually saved me money. He even throws in extras for you. Indo Pacific Sea Farms, IPSF, is the only place that I know of where you can get Strombus Grazers. The grazers are awesome little snails that reproduce like crazy in the aquarium. Also his tang heaven red, gold, yellow, and green are just like it says, heaven for your tangs. Let it grow in your refugium and it will give you the benefits of other macros while providing food for your tangs too. Anyway, I just wanted you to know that I have ordered from ipsf twice now and I have been very satisfied both times. Two thumbs way up.
