Ok..so after 30 years .. i have not seen stuff like this.. i posted this a week back.. but here are some fresh pics.. I am thinking of pulling all the frags... saving some of the water and cleaning out the whole tank.. wipe down the frag stand.. the tank ect.. and put back in.. problem will be fresh salt water... i can get the parameters close.. I am already losing frags like crazy to RTN and STN..
take a look...
