Thanks. It was fun to build. That piece is the product of about 20-30 bits and chunks. It has a dozen or so little landing pads to mount stuff to it.That’s a great looking rock structure! Were you putting them in dry with each swap?
I wish I managed my sand better. I went old school and left it be. Treated me well over the years but realized I always upgraded systems every 3 years and for the first time, I have a 4 year old system and I’m not liking where it’s headed. I’ve been reefing long enough I can see the tell-take signs of an impending crash if I leave it this way for another year or so.
Yes, it went in white & dry. I should have done it the right way as you are proposing, culturing it with tank bacteria. I thought I could pull it off, bit at a time. But no. Seven months of a slightly noisy biome. That system was so simple and stable for so long. Testing weekly, I could predict ALK, NO3 and PO4 almost dead on every time. Just bump up the DOS by 10ml every month or so.
Again, it could have been worse. I can't recall any mortality but the rocks are continually covered in evolving gunk.
