Now that this thread has officially been hijacked..some of this may also apply to the OP but I hope not if he is spending $500 on coral at a time...
Tex, I just responded to another thread of yours regarding diatoms during your initial cycle. I then checked out your threads and noticed you started the tank on August 10. It would not be a good idea to get any coral 1 month in. Starting coral within 3-6 months is still a crapshoot. It is probably wise to wait a year for a well established system for any coral but I know it's tough to wait.
Unless you are referring to another tank then I would wait but it's your money and your tank so if you must have at it.
I know Zoas are soft corals and can tolerate lower quality water but before you even start I would make sure your PH, SG
and temp remain as stable as possible. Any type of big swing in these three can lead to quick death.
Then you want to have your nitrates and phosphates as close to zero as possible. You will also want to start testing and monitoring the CA
, and MG
in the water to make sure it is adequate. Most salt mixes and nearly all reef salt mixes contain enough of these elements to replenish your tank with regular weekly 10% water changes.
So to answer your question I would get more LR
and not the zoas right now. There will be more zoas when you want to add them lol.. I hope that helps a little.
