SPS Bleached

How come your alkalinity is so high? Are you dosing something for alkalinity? what type of salt are you using?

You just have to keep in mind that with very low level of nutriment it is a risk to have RTN or STN when you have such high alkalinity. It is not safe to keep your alkalinity so high.

First step is to raise your magnesium and calcium slowly, but don't dose anything for alkalinity until it drop lower. If you don't have much in coral it may take a while before your current alkalinity level drop.

But before buying any delicate SPS I would get these value: calcium 420, magnesium 1350, alkalinity 8. Then try to keep this stable and you will be fine.

It's high just for fun, as far as I can tell. It's always been high. I even run zeo and have very little nutrient. I supplement with a Ca reactor and use RBS salt. It's been like that for 16 months, so I'm not too worried about the perceived dangers of high alk. I did read on the Internet that it's bad, but you can't believe everything on the Internet. Nasty place, that Internet.
Only RTN I've had was yesterday, and that probably had a lot to do with the frag falling into my torch coral

im not anal over my parameters these days the way i see it is all my corals are doing well both sps and lps , im doing regular water changes equipment is good so why fix it if its working well.

even with high " nutriments" my sps are doing well i would also second that it was prob a acclimation issue of just not taking the move well give it another try

huh...I was talking to nanomano, not to you. You know the risk of running with high alkalinity and low nutriment, then you do what you want

I know it's all over the net but I beleive it because I have very experienced people telling me about it and I do beleive them because some of them have 30 years of experience in saltwater and a lot of them with corals.

I also know a lot of people who did have RTN and STN all the time running alkalinity higher than 10 with low nutriment, and that resolved when they lower the alkalinity.

You might just be lucky

It is a risk, so once people know about it, they do what they want.

wow I went to bed and you guys have taught me a lot here! not to sure why the alk is high, it always has been, with lower CA. hopefully it balances out

Here is a thread on Reef Central where people discus the effect of high alkalinity with different setup. It is interesting to read about all these people experiences:

Daniella is right about low nutrients and high alkalinity, but that is more of an issue with ultra low nutrients when carbon dosing. That's why you see Zeovit recommending 7 dKH.

For the newbies, carbon dosing is not the carbon you put in the filter.
