Hello all! I'm in the middle of a war between two LFSs (who's names/locations will not be named for good business reasons.) I live nearly the same distance between the two, which turns out to be a two hour drive minimum to shop for marine fish and inverts & supplies. My first store I started...

So I got some refractometer calibration fluid and I can't believe how off my refractometer was. I usually calibrate it using my DI water or Distilled water, but when I put the fluid on it which calibrates it to 1.026 it was showing that I was showing 1.030+. So I set it and now I need to add...

I just got a Pinpoint PH controller in UPS (used) and the probe was in a bag, in a bag, in a bag, that was in a cup of Salt water. It leaked. The probe is still moist and there is still some water in the bags. How shoul dI store this untill it get it home about 6 hours from now? All I...

This guy just finished his first year of dental school and was in the middle of moving. He knew he would not have time to properly care for the system anymore. He had been trying to sell his set up for a few weeks and only sold one large rock with some leathers on it. He posted on another...

Ok stupid question, is there any place in the area that I can get ph calibration fluid of the 10 range? I am guessing no but... I ordered 7 with my controller, did not realize it required a 10 also. Would have been nice if it stated that on the site.

my water is regestering a spec grav of .025 which is good but i've had the tank for about 2 months and have never had to add fresh water, yet it never needs to get any more salty. the tank does not evaporate much at all, and when i do have to add water i check the sg and its 025 so i just...

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...

has any ever recycled the calibration fluid, using it once than storing it for later use?:confused:

So, we keep up on our testing of tanks, but its such a hassle to get sticks and all that crud. We would really like to get a digital tester, anyone have any good ones? price may be part of it, but if its worth it, so be it. We have 2 fw, 90gal & a 30gal hex. a newly started 30gal sw. or if...

My pH monitor went nutso this morning. My normal check of the tank, my monitor read 14.62 this isnt right. :rolleyes: So, i took it out, cleaned the probe. Its not a battery, i am using the adapter. I tried to calibrate to 7.0 and 10.0 with no luck. Could the probe have gone bad already after a...

Well I just bought another refractometer today so I could have one for my tanks at work and one for at home. They are off from each other by.005 I calibrated them in the same room with the same water so there is no temperature fluxuation and I tested the same tank water. I know people have had...
