So here is day 2 of adjusting the rocks shifted stuff around some and added a few select peices of branch rocks. The larger structure on the right is the orginal big peice and a few smaller peices kinda in a stack.
They should easily be removable if ever needed while the 3 main structures are semi heavy 30lbs or so each. If I hold my mouth in a proper frown and man up I should be able to remove them as well.
There are a couple of caves and a few holes scattered for fish to swim through. Maybe not enough only time would tell.
I also added 90% of the crushed coral I have left. The other 10% will be a crazy proccess to scoop out of the bottom of the stock tank. I'm planning to have multiple wrasses in this tank so there is a solid possibility of me filling in the back of tank with a crushed aragonite sand, hopefully small enough for wrasse to burrow into, won't get blown around and hopefully won't mix to badly with the crushed coral.
Otherwise I may consider putting some type of diy acrylic divider (or a solid line of smaller rocks serving same purpose) 2-3 inches high running front to back in the tank. To one side of the tank at maybe 1/3- 1/4th of the tank. With the smaller side being the special grade type aragonite.
Open to thoughts on this subject of substrate in a portion of the tank that's wrasse suitable.
Failing that, I'm a little over a 5gallon bucket short of crushed coral. Neptunes sales it but it's $6.99 last I saw. So would be insanely expensive when all added up.
Lastly I added a ton of live rock to the sump. One smaller peice of branch rock was the only thing dry added to this tank.
