Fellow Reefers,
I have relativly new to Reefs about 18 Months. I have a mix of sps and lps . I have been seeing brownspots on the Frogspawn and Goniopora. Also it feels Itchy when I put my hands in for maintiance .. Also I have Some softy and 1 Urchin im my tank. I have a GFO and a Sump. Is this bad ? What can I do about this ..
Thx
 
When was the last time you changed your bulbs? last water change? and what are your tank params?
 
Are you seeing brown spots anywhere else? I see you have a bunch of wrasses in your sig; Melanurus wrasses typically eat flatworms, so I doubt that is the issue...
 
My Tank params are
Ca 480
Dkh 9
PO 0
Nitrate 5

Every week I do water change of about 25 Gallon ..

It's been 9 monnths I have changed lights .. How do you know when to change the MH ?

Also I do not see brown spots an where else currently !

Will upload pictures shortly ..
 
Is the itching something new? And I am not a MH expert nor have I ever used them. But i thought they were changed every 8-12 months? maybe yours are nearing the end?
