Deb,
I know your heartache......we have shared our frustrations over the years, but somehow we keep going. I think somewhere deep inside... we all want to have a tank like Snappy's... that is why we keep going.
I have finally found the secret (I hope). After 5 months on ZeoVit, my tank has never looked better. bright colors on my SPS, no hair algae, excellent polyp extension and fantastic water clarity.
Before you throw in the towel....... try Zeovit... you will be sooo glad that you did !!
Deb ....come on over and see my tank !!
