You said you were setting up 4 tanks right? Are they all the same size? What do you plan on propagating in the others?
This will be interesting to see your progress.
The other tanks are not the same size 1 is a 92 gallon that will house more sps, lps and anemones
the 3rd tank is a 20 long that will go next to the one you see now that will house shrooms, xenias and polyps trying to keep them under control since they grow like weeds.
the 4th tank is still undecied since we will have a ton of room with the other tanks but I think i will still set it up or use it as a QT for my clients fish as i order them in before placing them in the main tanks.
This morning I added 70 lbs of sand to the tank and it is still not enough i added 50 lbs of south down and 20 lbs of aragonite I am going to add another 20 lbs of aragonite tonight and mix things around. since i used south down the tank should be clear in 2 days but we will see I will post pics later tonight.
