Jpowell490 Posted November 13, 2013 Share Posted November 13, 2013 Hey all, I will do an introduction a bit later as I am new to the forum, but I have a question. I need a little input here. I normally use RSCP and Aquavitro Salinity in my water changes. Well, last night I decided to use some Reef Crystals. Did a 10 gallon change on a 60 gallon tank. My normal, once a week. Use RO/DI water with 001 TDS reading. Salinity (35ppt) and Temp are all the same. Looked at the tank this morning and had a piece of my Acro Secate that looked purple on the ends and bleached in the middle. Just one little stalk. Some of my other corals looked "lighter" in color as well. Any thoughts on what could have caused this? Nothing at all changed and here are my parameters Temp: 79.8 Salinity: 35 ppt Ammonia: 0 KH: 11 Calcium: 400 Nitrates: 0-5 PH: 8.05 Phosphates: 0 Mag - No idea Nothing looks terrible, but there was definitely a change. Wondering if it was for the better or worse? Quote Link to comment Share on other sites More sharing options...
Jpowell490 Posted November 13, 2013 Author Share Posted November 13, 2013 Mixing up another 10 gallons of RSCP. Never using Reef Crystals again. If that is your thing and you use it, great. I have never had much luck out of it myself. I guess using Salinity and RSCP have spoiled me lol. Worst salt I have ever used was TM Bio Actif.....

+KimP Posted November 14, 2013 Share Posted November 14, 2013 Welcome to the club! I've certainly read of this happening but I don't have any personal experience. I hope the damage is minimal and everything gets back to looking good. Quote Link to comment Share on other sites More sharing options...
Jpowell490 Posted November 14, 2013 Author Share Posted November 14, 2013 Hi KimP, Yes, it wasn't a lot, I just pay extreme attention to the tank every day and noticed quite the difference this morning. I just finished another water change with RSCP. Have had great luck out of that and Aquavitro Salinity salts. Will post a few pics in the reef keeping forum.

+KimP Posted November 14, 2013 Share Posted November 14, 2013 I've been happy with RSCP too. I'm looking forward to pics! Quote Link to comment Share on other sites More sharing options...
victoly Posted November 14, 2013 Share Posted November 14, 2013 You left off alkalinity as a test parameter. When it comes to corals suddenly changing color, alk swing is a pretty common cause. Quote Link to comment Share on other sites More sharing options...

Timfish Posted November 14, 2013 Share Posted November 14, 2013 Welcome to the club! Usually I see partial bleaching as a result of either lighting or temp but that seems to be ruled out in this case. Here's two research articles that at least will waste some time reading: Effects of cold and heat stress http://www.nature.com/srep/2013/130312/srep01421/full/srep01421.html Corals experience shapes susceptibility to bleaching http://www.mendeley.com/catalog/experience-shapes-susceptibility-reef-coral-bleaching 1 Quote Link to comment Share on other sites More sharing options...
victoly Posted November 14, 2013 Share Posted November 14, 2013 KH=Alk Im tired... 11 is kind of on the high side of normal, if your wc is high in alk it might have pushed it up higher. Quote Link to comment Share on other sites More sharing options...
Jpowell490 Posted November 14, 2013 Author Share Posted November 14, 2013 Actually 11-12 is what my alk stays at. I have never been able to get alk lower in any of my tanks. I know one time in my old reef tank, it was up to 18 and everything was flourishing. Thanks for the input. Quote Link to comment Share on other sites More sharing options...
mdavis735 Posted November 14, 2013 Share Posted November 14, 2013 I always kept mine around 12 on my 92. On the Biocube it's 8, but I'm gonna raise it soon. Quote Link to comment Share on other sites More sharing options...
+olaggie01 Posted November 15, 2013 Share Posted November 15, 2013 Similar thing happened to me recently. Not sure if I can contribute 100% to the water change, but I mixed in some Seachem Reef Salt to my normal NeoMarine and it lightened quite a few corals. Perhaps corals get used to certain elements?

Jpowell490 Posted November 16, 2013 Author Share Posted November 16, 2013 I think they definitely get used to a particular salt. The best salt I have used is Aquavitro Salinity (Seachem). I have great polyp extension and colors with that salt. The RSCP is good, but not as good as the Salinity. Quote Link to comment Share on other sites More sharing options...
