in short: lux is a unit of measurement of light intensity as perceived by the human eye. Kelvin is a measure of the spectrum of light as related to blackbody radiation. wikipedia is your friend...

what is the margin of error on the test kit? .05-.10 is an amazingly small amount... even twenty times that is little to be concerned about...

I reef smarter, not harder. :rock:

get a syringe at CVS and then you can use the little disposable plastic condiment cups. very easy to swirl those to mix up the reagents, and you can choose to clean them or toss them.

I'm finally to a place where I don't spend all that much weekly/monthly. Way under $100/month. If I were to average it out over the last year, I'd say somewhere around $60-70/month. Electricity is $20/month, but beyond that, I haven't spent much money in some time. Not setting up new tanks...

ALWAYS, ALWAYS, ALWAYS watch it eat before you bring it home. If you want it to eat, there is never an exception to this rule. Some fish just don't acclimate well. Some need very mellow time before they're introduced to a display with other fish. Let the LFS eat it if a fish isn't healthy.

a couple things: First, calcium carbonate is NOT due to just high calcium. it is high calcium and carbonate. There is a threshold where you will observe massive precip like that, but it's generally due to having both levels too high. You'll also want to check your magnesium levels as Mg is...

yep, you want to keep things in line rather than "high" IMO until you have a very high demand, kalkwasser is your best way to supplement. It is very easy to cut back on (just don't mix it as potent) and has other benefits that will wind up being quite beneficial (precipitates phosphates...

Your ca/alk balance is untenable. At this point a water change would be best, but you could also just wait. Whatever you're dosing, cut back. my guess would be that you're doing 2-part and overdosing it. This is much less likely to happen when using kalk. Don't stress too much, but do cut...

not inherently. What it really means is less rapid gas exchange. in pure water it's really unimportant once it's mixed up and stable IME.

I'm also interested in what a steel stand would run. I'm sick of my stand and could use a new one...

chances are he'll be fine if he was in good shape going in. feed him like there's no tomorrow and you'll be fine. some tangs show ick every now and again even after years of being in a tank.

local reefers will be amazingly cheaper...

just finished finals today! maybe you can swing by tomorrow to grab that reactor

I wish I had more motivation to feed them. I break up the massivore pellets from hikari for them.

we'll see where I get for next year, but now I'm taking o. chem, vector calculus, and modern physics at saddleback.

perfect. pm your phone/addy and the model number/details of the unit. Consider it sold, I'll be there Friday. good luck with your finals, I know I'll need some...

I'll bring cash, but can you wait until thursday evening? I've got finals until then.

I'll take it, with the new filters.
