Hi Guys
Wonder if anyone can help with any info/reasons on the following happenings:
My brother-in-law has a small marine tank 3foot x 1foot x 2foot.
Up to date it would have been running for 6months.
Its very basic with no real significant filtration or sump.
About a month ago, his tank water went murky and the fish started coming to the surface for air so he rushed his corals down to my tank so they wouldn't die and headed down to the beach to get some NSW for a water change. He did almost a 50% water change that same night and by the morning his tank was clear again.
Since then his tank has been fine but he's kept his corals with me.
Monday night this week, the same thing happened. The water went so dirty you could only see about 3cm into the tank. Unfortunatly this time all the fish died!
He did a 20% water change sunday just before this all happened.
Any ideas what could cause the water to change so quickly like it did!?
He hadn't added any new stock since the first crash. I still think it was an over stocking issue, but i'm too new to be able to know for sure.
