    Exceptable as a reference?

    This information is from one of my old books. Is this information still correct and good as a reference?
    The values after the = signs are what the book says is ideal. Tthe values in the brackets are said to be the acceptable range.

    Salinity = 1.024 (1.020 1.026 )
    Temp = 78* F. / 25.6* C ( 75 -82 / 24 - 28)
    Redox = 325 -350 mv. ( 250 -400 mv )
    ALK = 4 meq/l ( 2 6 meq/l )
    Carb Hard = 12 dkh ( 5 - 20 dkh )
    PH = 8.2 ( 7.8 8.4 )
    O2 = 5.5 ppm ( 4.0 7.0 )
    Ammonia = 0.0 ppm ( 0.1 1.0 ppm )
    Nitrite = 0.0 ppm ( 1.0 3.0 ppm )
    Nitrate = 0.0 5.0 ppm ( 5.0 50.0 ppm )

    Carb Hard of 12dKH seems high.
    Aiming for 10 is more of the norm, and Ca? 420ish....

    This what I shoot for:

    Salinity = 1.026
    Temp = 80 - 82 F
    ORP = 350 - 400
    Calcium = 450 - 500 (Alk to balance)
    PH = 8.2 - 8.4
    Ammonia = 0
    Nitrite = 0
    Nitrate = 5 - 10

    I'm a firm believer that 0 nitrates is a bad thing, especially if you have clams.

    I'm curious...how do you maintain Nitrate at 5-10? Is it the amount of food you feed/overfeed? Filtration?
    thanks.

    OSD, i wouldnt have any ammonia or nitrite in an acceptable range (other than in a cycle). Carbonate i would say around 8 dKH Ca ~420.

    Flame, you dont find 500 high for Ca?

    thien, feed enough and you will have nitrates. but keep a PO4 resin to remove the PO4 from the heavier feeding.

    I always used to keep my nitrates low, below 2. Then I was having trouble with a clam and I emailed Tim Tessier at SeaCare (where the clam came from). He told me that he wouldn't keep clams in a tank with such low nitrates and that they should be 5-10. I'm a heavy feeder so it wasn't too hard to get the nitrates up higher and I haven't had any troubles with clams since.

    My reef calcium is almost always dead on 460, has been for years. It is just where my tank likes to be I guess.

    I think that a salinity of 1.020 is too low for a reef- I think 1,021 is a minimum
    75-82 is good
    redox is fine
    alk of 2 is lowish and 6 is highish (those are technical terms!)
    I'm with tangy here I'd say a decent dkh range should be 7-14 shooting for 10.
    o2- not sure
    amm. and no2 zero zero zero
    no3- clams definitly like some no3 and inverts don't really care about up to 5-10ppm.
    fish won't really care (except sensitive stuff like angels) up to 50ppm or even higher- but you'll probably be getting algea.

    Thats pretty funny. I think a good reference if your're after on eis in Bournemans latest book. MrFiXIT has my copy otherwise I wouldve quote his ranges. The other comment I can make is the temperature range. Much has been written on this, and personally I would think it can go as high as 84 from what i've seen. Moot point I suppose. Its the low end I find interesting, Does anyone keep their reef dialed in below 77F? Would be fun to here from you CHILLER guys, if any........

    I think the idea with the range numbers is that if the numbers move out of the ideal you would not go into panic mode if they are within the range. I think it is safe to say that the ideal is the goal to seek if the numbers that are listed as ideal are not to outdated. I will let the thread run and then read the whole thing through a few times and come to a conclusion based on this thread and info from some of the polls.
