Hi to all,

I need some help and advice please.

My new tank has been running fine now for around 3-4 months
I purchased a clown tang around 2 week ago he didnt get on with my
powder blue to start with but things soon carmed down.

Problem !!!!!!!!

3 days ago powder blue started with white spot.

I have been running uv for 2 months now ( new bulb fitted from start )

Can anybody give me some advice how to stop to white stop.

My tank is a 5,2,2 with sump.
Tank is a reef tank which contains acros, and lots of other hard corals ( now softys )

Please help as i have never had this problem before and donot now what to do for the best ????

Thanks ian.

A combination of sand cleaning and lots and lots of very regular small water changes along with a diet of rich dry, frozen feeds and sea veggies is probably the best initial course of action provided all the fish still feed well

how about adding ozone to the system??
