Ok I have had a loooong grudge going on with my tank.....Had a huge die off killed everything but a filefish ...tore down tank and rebuilt it added let it cycle for a month restocked with fish everything looked good for a few months fugly zoos came back fast killed them off by putting rock outside in a pail of snow. Next day woke up to a foul smelling dead tank everything dead bristle worms included...frigging fugly zoos. 99% water change this March will be 2 years with no livestock in it still adding 5gal a water a week there is nothing alive look like the surface of the moon no pods no bristle works no feather dusters everything still running like a functioning tank except the lights are off. The tank has never been cleaner in it's life it actually looks awesome. Think I gonna add some LR soon to try and reseed it. Tested couple weeks ago and it was pretty good.

....and the rock is still outside in a bucket

Purple bubble algae in my frag tank is driving me insane. Next weekend ill be doing a hydrogen peroxide dip for everything then transferring everything to a quarantine then eventually into my new frag tank
