STN/RTN every time I purchase a colony from same LFS

Would much rather by a frag of something grown in captivity where it's used to growing in a box of water and I know what I'm getting (and not getting, i.e. pests).

I dunno, I have yet to get pests from wild acro colonies, but am on 6 times and counting of getting pests from frags through other hobbyists.

Where in the tank you placing the corals? What Par are you starting them at? No mention of type of lighting on your tank. What are your Par levels in the tank. Placing a coral under a Par level with out checking where the coral has been can cause problems. Many corals in stores have been light deprived for weeks maybe and then placing them under a high Par without a very slow raise in Par can do it in the time frame you are talking.

My input tds is 150, 30 post membrane and 0 post DI after I changed it out. Looking for why my membrane is only rejecting around 80% and it's less than a year old.

I have tons of flow with 2 Gyre pumps pointed at each other and my lights are 2 x AI 52's mounted 10 inches over water and my tank is 30 inches deep. Both recent colonies I've lost (1 has stopped RTN/STN) started low and moved up after 3-4 weeks.

Quick update: since I've lowered my temp to 78, increased my carbon dose, my RTN/STN on my main piece of acro that was slowly bleaching has stopped. My Nitrate is undetectable with Red Sea Pro, Phos undetectable by Hanna Checker and polyp extension on every SPS is insanely good. My Alk is holding steady at 7.7 too. I think my issue was high temp and possibly difference in Alk from my LFS to my display tank.

I'm going to purchase 1 more SPS colony from them later this week and see if I get any RTN/STN in 30 days and then I'll know for sure.

Thanks for the advice all.

Given the problems you've had with SPS colonies from this store, why would you try to add another one now that conditions in your tank have apparently stabilized? I'd strongly recommend that you let tank settle for a few more months before adding anything else.

Good luck,

Mike

you are purchasing wild/maricultured colonies

i'm a PT worker at a Coral store.

although beautiful, wild cut acros are doomed for failure unless they are in a system where water quality is extremely clean by doing 25% water changes a WEEK. lots of flow. lots of heavy 14k MH light. no T5s. no LEDs. MH only. lots of water changes.

aqua-cultured acros are a lot more stable, especially ORA ones.

good luck. buy only aqua-cultured! avoid wild cut like the plague....

LFS gave me a free, good sized, frag from a new colony of wild caught acro. I'll see how it does it my tank. So far the PE is great and it hasn't lost any tissue.

Quick question. Will my STN/RTN colony that has stopped losing tissue eventually grow good tissue over the dead spots?
