DDiver March 3, 2009 Share March 3, 2009 Where does everyone keep their alkalinity?the recommended range is 8-12dkh but I wanna know where everyone is seeing fastest growth. Link to comment Share on other sites More sharing options...
Almon March 3, 2009 Share March 3, 2009 I try to keep it above 8. It is typically between 8 and 9. Link to comment Share on other sites More sharing options...
flowerseller March 3, 2009 Share March 3, 2009 And I shoot for 10-12, w/salifert test kit. Link to comment Share on other sites More sharing options...
zygote2k March 3, 2009 Share March 3, 2009 The average reading I get on the 90 w/ SPS is about 3.14 meq/l. Can't seem to get it higher no matter what. Link to comment Share on other sites More sharing options...
phisigs79 March 3, 2009 Share March 3, 2009 I like 10-12 DKH to allow for a little drop without problems. I have been battling a low ALk lately and bumping it up using two part. Link to comment Share on other sites More sharing options...

Origami March 3, 2009 Share March 3, 2009 10 dkH. Link to comment Share on other sites More sharing options...
mogurnda March 3, 2009 Share March 3, 2009 Anything above 3.25 mEq/l (9 dkH) is fine for me. Link to comment Share on other sites More sharing options...
CHUBAKAH March 3, 2009 Share March 3, 2009 Just remember Billy, unless you stopped running the Neo Zeo system, what others keep their system at really plays no part in you're set up. Most of us are around 7, but with any of these low nutrient systems you want to max out around 8. Link to comment Share on other sites More sharing options...
stratos21ss March 3, 2009 Share March 3, 2009 Just remember Billy, unless you stopped running the Neo Zeo system, what others keep their system at really plays no part in you're set up. Most of us are around 7, but with any of these low nutrient systems you want to max out around 8. Still confused on this a little.. what is the limiting factor in low nutrient systems that prevent us running much higher than 7? I am running ultralith and am pushing it past 8, but it is a chore to keep it there (it will settle at 6). What is using up the alk so much and does having such a low alk impact growth? Any links that explain this appreciated. Link to comment Share on other sites More sharing options...

Any links that explain this appreciated. In carbon-dosed systems, there have been reports of SPS tips being burned at higher alk levels. I think that's what Mark's referring to. From: http://www.reefkeeping.com/issues/2008-08/nftt/index.php Burnt tips - Some users of organic carbon dosing have reported the tissue loss at the ends of their SPS. These "burnt tips" have recovered once the user reduced the alkalinity levels within their tank to alkalinity levels closer to natural seawater (7-8 dKH), pictured below. Unfortunately, the root cause for this is not known. Link to comment Share on other sites More sharing options...
DDiver March 3, 2009 Author Share March 3, 2009 thanks for clearing that up Tom, I've been running mine at 7-8dkh since I started with NeoZeo and forgot why I was keeping it that low.. I do see growth but just not anything super crazy like I see from other people's tanks. Link to comment Share on other sites More sharing options...
