Cal, Alk, Mg in established systems

[fishytime]

I havnt even checked V2 for any of the big three in a year, but before I moved V1 was consuming close to a gallon of Randys recipe of Ca and DKH in a week and Mg was something like a half a cup every two weeks..... Mg dosed manually and Ca and DKH dosed with a profilux ..... Mixed reef, three years old

Does this mean you are not dosing in V2???

3 year old 300g system: aprox 250mL alk and 200mL calcium (2 part) per day.

hmm,

why am I using so much,

baking soda 590gr/gallon mix in 5 gallon can (3 gallon mixed up at a time), I dose about 620 ml a day – spread out over 8 dosing's

Calcium:

I was mixing 500 gr/gal mix in 5 gal can (3 gallon mix at a time) dosed about 610 ml a day – spread over 8 dosing’s

but Calcium was rising and had lots of precipitation, so went with 20% less calcium at the same gallon and dose the same ml at this time

I changed and went lower on calcium yesterday so have to se upcoming week – weeks to find out if this is better


I have about 400 gallons of water in my system,

70% SPS and 30% LPS

tank is about 2 years, SPS corals are medium size

You do have more gallons than anyone who's posted so far.... And your solution may be more diluted than others

What's your Mg at?

mag in around the 1350 to 1400

I gust use the standard recipe:

http://www.reefkeeping.com/issues/20...hf/index.php#5

I do feel I use alot as well, but I dont know, it is what it is I think, thats why it is interesting to se what others use.

I think I'm about 2x as much as others,

and I even find that I defenatly dont have a over crouded SPS tank

i do have everything covered in nice purple coral. algea

I do a 40 gal water change each 2 weeks now, and when mixing new salt I bring the Cal up to 450 and the mag to 1400 by adding some calcium chloride and 5 to 3 magnesium mix
