Kissman,
Also, if you need some nitrates, a quick way to do it is shut the skimmer off! You can shut it off 4 or 5 hours a day. That really helps!
Kissman,
You are constantly changing too many things. Stick to the basics, and your tank will come back. I would not pull out the rock and sand unless tests warrant it to do so. Too many phosphates and too many nitrates.
I would keep the course and give it time. Also, boosting bacteria levels in a tank that does not need it is a waste. Totally useless. You need to find the balance. The balance for my tank is: Feed enough to see phosphates and nitrates rise up a bit from zero.
Then I get colors and good growth. No vodka dosing or pellets. I dont need them. NO REACTORS unless needed. They strip everyhting out of the water.
As the water dirtys up a bit, you may need to increase lighting some. But let the corals start to lose color and turn brown to tell you that. mYou should be getting a nice film of algae on the glass every 2-3 days. That you have to clean off.
That's one way I can tell my tank is dialed in. I agree with what adrnlrsh has posted too. You gota feed that tank!
I also had a DSB in my sump btw. I didn't touch it. Just added fish. I don't think Xenia will be able to consume everything. I think you need to increase it regardless of the Xenia, you can always remove the Xenia (pruning) later.
I don't think Xenia survive if you add them to a ULN system. I think they strip a nutrient rich system making you think its ULN
I am actually not running anything or dosing anything. It was suggested by a few people to return to the basics. Just run skimmer, lights and live rock. I am running just that. I was carbon dosing vinegar and i guess over dosed and thats what got me here. I stopped that back in Dec. I have thought about adding 3 more Chromis however I believe with the Xenia that I have in the all I will do is fuel its growth by adding more fish? I have bought some Sodium Nitrate to dose but I have not doesed any. I would love to, but i want to try running just the basics for a while like a few people have suggested. I would actually love for my NO3 to be at 1-2ppm at the moment my PO4 is 29ppb. which is as high as I would want it to go. However I will not run anything unless I start getting a lot of algae. I use to do two 5g water changes a week and have been doing a 5g water change every Sun. maybe I will drop that back to every other Sunday. I have started to slowly remove my sand bed as I do water chnages as of this morning. I am also toying with the idea of replacing my live rock to get rid of the dang Xenia. I really believe the Xenia is about 70% of my problem. However as some have suggested it could be the DSB if thats the problem the Xenia could be saving me from a crash? If so once I remove the sand bed maybe the Xenia would die off.....
1-Replacing some or all of your live rock is a good idea IMO...get rid of the xenia. It is too prolific to try and maintain...it will always regrow and overwhelm.
2-Take out the DSB OR at the very least vacuum the @#$* out of that bed.
I would add back already CURED CLEAN live rock. If possible get it from a fellow reefer to save some bucks.
If you dont feel confident that your corals will make it through this process set up a small 5g tank and use some of the water change water to hold the corals until the tank is ready. If you have a HOB filter or something like that you could set it up on there but sm water changes and a shop light can keep your struggling corals alive for the while. This way youre not introducing the corals to the ups and downs of the minicycle (of sorts) thats going on in your tank.
follow Elegance's instructions and after a few days you should be able to add back the corals to your tank. dont rush into getting more corals...I would let the tank settle in for a month or so and feed the fish regularly...maybe add 1 or 2.
Kissman, after reading and following this thread I've come to the conclusion your best bet is to give your corals to someone with a stable tank or your lfs to hold or as a donation. I would then shut your system down and start from scratch or start your 120. You corals have been through to many changes and instability and it will probably take them 6 months in a stable system to recover if ever. Next time around go back to the bare essentials regarding equipment and additives. Start your next reef with minimal skimming and fresh cured live rock and live sand. Start off with just one fish and wait a bit to put your first coral in. Then when you hit the three month mark, add a couple more small fish and maybe one more lps coral. Then around the 8 -9 month mark, if your tank is stable and healthy and you see good growth your lps, add one sps. If it does good then add more slowly. Feed your fish daily just a small amount, and do 10% water changes weekly. Your coral load will be small so you won't need to add any anything and your water changes will provide all needed items. Don't add any reactors or dosing pumps or other chemicals to your reef unless you know 100% for sure the cause and effect. Once you have a stable sps tank, then test and track your results. If for example you start to notice good sps growth and you're testing low on calcium or alk experiment with a calcium alk doser. If you see any negative results you will know the source. if you start from a healthy tank you will know what works and doesn't. In the last few years its amazing how many new products have hit the market, and to be honest some are beneficial but I think most are just causing problems. I've tried many and truthfully probably 90% have either done nothing or caused problems. Ultimately kissman, keeping things simple, stable and being patient will bring you good results. I do believe you will need to start over from scratch though.
