hi i'am new to the forum my torch coral is not looking to healthy it has black stuff all over the base and i think i'am losing heads i have a smaller bit which is doing really well i have posted a pic of the good one and the diseased one.

not sure if i should scrap the black stuff off

i have had my tank setup for about 3 months the fish and other corals are doing great i check all my waters and all is fine.

as i said i have only had my tank for a few months so any advice would be appreciated

many thanks ian

Hi, I'm no expert on marines I'm afraid but if you could post the exact water test results and confirm the salinity level that might give us something to go on, one man's 'fine' can be another man's OMG!!! What sort of other fish/corals do you have? And what size is the tank? A bit more info will help with the bigger picture

The pics haven't come out, have a look at the site help and see if you can figure out where it's gone amiss http://www.fishkeeping.co.uk/modules/faq/index.php?cat_id=4#q11
