lenver Posted October 31, 2014 Share Posted October 31, 2014 So I have a question, specially on the oh result, don't really know what it means. CA is 500 so it's good MG is 1360 also good But for KH took .40 ml which is Meq/L 2.0 and dKH 5.6 I have no idea what that means Quote Link to comment Share on other sites More sharing options...
victoly Posted October 31, 2014 Share Posted October 31, 2014 That is a very low alkalinity. You wanna try to (slowly) dose until you get up to at least 7. 8 gives you a little more cushion. Test again before you make any changes. Quote Link to comment Share on other sites More sharing options...
Reburn Posted October 31, 2014 Share Posted October 31, 2014 Thats pretty low. I'm not exactly sure what natural seawater i think it's 7.8, but I shoot for 8.5 to 9.5 ,most people agree acceptable ranges are 8-11.5. I would raise it very slowly. You can really irritate coral changing the alk too fast. Especially SPS. Quote Link to comment Share on other sites More sharing options...
Bpb Posted October 31, 2014 Share Posted October 31, 2014 Meq / L and dKH are the same thing. It is just a different unit of measurement to express the same parameter. Most people seem to favor using DKH though. What does it mean? Well if you are going by textbook balance numbers, your alkalinity is a touch on the low side for a calcium reading as high as you got. But if your livestock looks happy and healthy, it's more important to have stable parameters then wide adjustments chasing some magic number.

lenver Posted October 31, 2014 Author Share Posted October 31, 2014 What would I be experiencing on my coral with KH like that Quote Link to comment Share on other sites More sharing options...
FarmerTy Posted October 31, 2014 Share Posted October 31, 2014 I usually observe STN on my SPS and sometimes melting of some zoas. Sent via Tapatalk Quote Link to comment Share on other sites More sharing options...
lenver Posted October 31, 2014 Author Share Posted October 31, 2014 I actually have an issues with zoas lost a bunch of them and I'm thinking it happened when i used atm agent green, but that's supposed to bind a calcium molecule with a phosphate one, after using it to try and control an issue with green hair algae my zoas started to melt at which point I stopped. But don't know if this effect in alk made this happen, everything else in the tank seems to do well Quote Link to comment Share on other sites More sharing options...
Neon Reefer Posted October 31, 2014 Share Posted October 31, 2014 Best practice: Always make sure foundation params are within guidelines before making any changes to correct a problem. Ca, Alk, and Mg are noit only crucial to proper heath of cotrals and inverts , but the starting point for correcting any known problems. It helps reef keepers to make a motre educated "guess" at what may be causing the issue. Therefore preventing us from making the situation worse in some cases.

Manny Posted November 3, 2014 Share Posted November 3, 2014 I think the absolute best thing for you to do is test again and make sure it truly is that low. Quote Link to comment Share on other sites More sharing options...
