I agree with the rest of the thread... with that common of water changes and minimal bio waste in the water it should not take long at all for you to hone in on the best water types to grow zoanthids... I really like your idea for a SE Asia zoanthid tank... I LOVE the way eagle eyes look so you should have a nice setup in a few months!!! I am looking forward to seeing what you have created.... :strooper: but a word of advice, be patient with the growth rates... sometimes they grow fast, sometimes they don't... it is pretty much a luck of the draw on the growth rate.... :debi:
