"Curious about calcium" survey

[SeaHorse_Fanatic]

35g & 33g Kent's Liquid Reactor & NaOH

[sumpfinfishe]

27gl LPS/SPS reef, Kent's Liquid Reactor and Liquid Calcium

[christyf5]

90 reef, calcium reactor. Ca=420ppm, alk = 7.4dkH

[monza]

500g. including sump and frag tank, pretty much SPS and fish
-AquaMedic Calcium reactor
-Calcium 390-430ppm
-Alkalinity is 9-10dkh
-Calmax two part additive on hand for when I start playing with my reactor and screw it up.

If your thinking of what road to go down I vote for the CA reactor.

230g - clam/sps mostly...Ca Reactor 450 plus and about 9 dkh...been trying to boost the alk levels with some buffer, or the part one ( for no particular reason but just cuz THEY say.... )

67g - softies mostly. 2 part B-Ionic sometimes. mostly because if the levels are high, it keeps bad algae away. Ca 450 alk 9 Water changes to maintain mostly. ( southpark reference mostly )

33g - water changes only Ca 420 alk 8 dkh

I use the KISS principle.

75 gallon mixed with mostly softies and LPS with a few SPS thrown in for good measure. I don't test so I don't know, and I don't worry. I use no additives, just local water.

33 gallon with mainly zoanthids. Same as above.

It seems that I'm in the middle of the small tank vs. Big tank with a total volume of about 90 gallons. So far I add Ca+ and 2 part Alk buffers. I'm just wondering at what point does it become more economical to add a calcium reactor instead of dosing with additives.

[monza]

I'd guess at your size it would be better right now. IMO it also helps balance out the PH and Alk as well as maintaining the calcium. It's all so a cool piece of hardware which I think is half the fun.

If your not in a rush I "may" consider selling my Aquamedic unit in a couple of months. My tank has really out grown it's max output. Haven't even considered what price or any thing, just thinking down the road.

Down the road I guess, if the right deal comes along I might consider anything! Space under the stand would also be an issue though.

90g softies+anemone reef, no reactors, no additives. Ca=dunno/don't-care Alk=ditto

... I second the arguments for a calcium reactor. I realize it's a heavy investment but I have to tell you, when you get one you will seriously wonder how you ever got by without one. I never have to worry about training someone to do additives when I go away for a weekend or whatever .. don't even really have to test the water for parameters anhmore. I just check the output of my reactor, if it's output'ing the right flowrate and the pH is 6.7 ... I know it's "just right". Test once in a while for the fun of it but the results are always the same. I love that.
