Hi everyone I have a 180g reef tank with about 180lbs of liverock and a 2.5" sand bed. This tank has been setup for about 6 months in my house, was previously setup for 6 years from the person I bought it from.
The last two months have been hard for me, tons and tons of brown "spider webs" all over the tank. I'll clean every spot off the glass, and in two days it will be back. My tank is acrylic so I can't use anything hard or sharp to get it off so it is a huge pain.
I use RO
water every water change which is about 10g a week plus a top off of 8g of fresh RO
water for the evaporated water.
I have tried everything.
My tank has like no fish in it for its size.
One regal tang, small yellow tang and a mandarin goby. They are all under 3".
I have it stocked with corals... Too many to list... I use a 60g fuge with filter socks for intake then to protein skimmer and then caulpera macro.
Any help needed
