I've got a 29 gallon nano sps and I'm battling an invasive algae I've had for a couple years and it won't go away. I've tried rock cooking to no avail. My system runs very nutrient poor as my sps don't like to color up and remain faded. I run a phosban reactor and am BB so I see no detritus and I blow off rocks weekly. Algae on the glass only needs to be cleaned every couple of weeks. Every time I try and boost my fish feeding the caulerpa starts to pick up speed while my chaeto pretty much stays the same so I've decided to just pull out the rock and swap with some base rock I have in waiting and take all my sps and transfer to new rock. If I do this, will there still be spores in my water column that can repopulate the rock?
