I'm getting a feel of where reefers with SPS success keep their parameters at. Particularly Alkalinity and Phosphate. Please share nutrients in the discussion
 
Alk stays around 7.5. I intervene if it gets below 7 or above 8. Nitrates stay around 10 and phosphate around .1 with my normal water changes and skimmer. I dont do anything else to keep those in line and don't panic if they shift. If they head to zero, I up my feeding and consider it time for more fish.
 
My alk goes all over the place but I try to keep it at 8dkh ( can go as low as 7.6 and as high as 8.8 )
No3 I shoot for under 10 and po4 .08 or under.
 
Alk typically somewhere between 7-7.8dkh. PO4 usually .2-.3. nitrates around 12-25.
Acros start to get angry much above low 8's for me anymore. Don't ask why, because I don't know. I just shoot for In the neighborhood if 7.5 and everything does well.

your acros like a little more dirty water than usual. Every tank is different of course
 
Yes, that's what I'm finding out. The more I learn and read, the more I find that there really is no set of parameters that works for everyone.
 
red field ratio balance?
Is it? I don't know that it's relevant as that ratio is about carbon as well as phosphates and nitrates.

Those numbers are just where I ended up, with happy coral and no significant algae growth.

Obviously a lot of other 'stuff' which is probably not measured is also contributing.

what is red field ratio im sorry excuse my ignorance
 
Phofate 0.08-0.1
Nitrate 5.00-10 ppm
Kh 10-11…

dont matter if is hight or low … SPS like only 1 thing … stability! STABILITY! STABILITY!

!!!!!!!!! S.T.A.B.I.L.I.T.Y !!!!!!!!!


thats all… otherwise they will give you only headache .
 
Alkalinity of around 8.25-8.35. It can vary by as much as +/- 0.15 during the day, though - so a low of 8.1 and a high of 8.5. I only teat twice a day but it's fairly consistent. Nutrients are a bit higher but I really stopped paying attention to them as the corals are really happy for the most part.

I've got about a dozen SPS of all types: chalices, hydnophoras, cyphastreas, acros, etc.
 
My ALK target is 8.5, but as long as it's between 8 and 9, I'm fine and don't make any changes to my dosing.
If ALK drops below 8, I'll bump up my doser a bit to bring it back up to the 8.5 range.
If it rises above 9, then I back off the doser a bit to bring it back to the 8.5 range.
I make small changes to my dosingr schedule. I'll just back off or add a couple ml per day, so changes will take several days to happen. no quick swings.

last test results
ALK 9.0
Nitrates 0.5 ppm
phosphates 0.04 ppm

I have also experimented running my tank at lower ALK levels, like 7 and below. While everything was happy at ALK in the low 6's, growth was very very slow. bumping the ALK up to 8+ definitely speeds up growth.
