Does anyone re-use calibration solution pouch to calibrate PH controller? I have a reef fanatic PH controller, how frequently should I calibrate the controller using PH calibration buffer comes in pouch?

How often do you guys replace your refractometer calibration solution? Im guessing that there will be a bit of evaporation in the bottle, throwing off your calibration. How often before this happens on average?

Does anyone know where I can buy 4.0 and 10.0 ph Calibration solution for my Aqua Controller locally? I am in the cities right now, but will be passing through Rochester today. Also, does it need to be Neptune's brand? Thanks

It says in the instructions to keep the end wet. How important is this? I guess I'm suppose to use regular tap H2O.

I have a Gen-X CO2 regulator by pacific coast imports. It has a solenoid and a needle from MRC http://www.myreefcreations.com/caaccessories.htm at the bottom of the page. Currently the regulator is putting out an output pressure of 25. That is just a touch higher than I want. There isn't any big...

My RK2 screwed up and I had to reset it. I thought I had some 7 and 10 PH calibration solution but I don't. I hate paying shipping on items that cost $1. If I have to order them I will buy some other stuff with it I just hate paying needless shipping.

Anybody have any experience with this? Or, can direct me to a decent pH meter that is digital? http://cgi.ebay.com/New-Advanced-Aquarium-pH-Meter-with-Large-LCD-Display_W0QQitemZ350025815971QQihZ022QQcategoryZ117435QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

Hell again, I have a quick question about tds meter should I get a inline meter or hand held unit? I know the inline is better but will the hand held one be good enough?

My salinity is 1.032. What can i do to lower it? It is a 75 gal tank with live rock and live sand only.

I'm having issues with my pH--no matter what I do it won't raise. At one point it was around 7.8-7.9 in the morning and slowly rose over the couse of the day to about 8.2 max. Now, it's about 7.6 in the a.m., and rarely goes above 8.0 at night. We're using the buffer and nothing is...
