Directions & Dosage
MIXING DIRECTIONS
For best results, it is important to follow proper mixing instructions when using salt with elevated parameters like Fritz Aquatics Reef Pro Mix. See below for best practices when using RPM.
When mixing Fritz Reef Pro Mix, it is best to use RO/DI water quality checked by a TDS meter (TDS should be less than 10 ppm, 0 is preferred). Fill a clean mixing container (dedicated to saltwater mixing only) with desired amount of water to be prepared. For best results, use water between 70°-75°F (21°-24°C) when mixing RPM. Slowly add desired amount of RPM to the water to avoid an increase in temperature and precipitation. This helps to prevent precipitation of calcium, alkalinity and other elements. It is recommended to use a mixing pump and an airstone when mixing RPM. This will also help to avoid concentrated areas of material and precipitation. Using a properly calibrated refractometer, bring the water to the desired salinity. Once mixed to a clear solution, add a heater to the water to bring to the current temperature of your aquarium. It is recommended to allow two hours before performing a water change. If water does not mix clear, please contact us for further mixing tips before performing a water change.
DO NOT MIX DRY SALT DIRECTLY INTO SYSTEMS WITH LIVESTOCK PRESENT!
CAUTION: Keep out of reach of children. Not for human consumption. Generates slight heat when added to water; avoid handling with wet hands. Contact with dry powder may cause skin and/or eye irritation. In case of contact, flush eyes with cool water and seek immediate medical attention.
Storage: Store in a cool, dry place. Keep product tightly sealed.

Fantastic for the money
I use this watch at work, so about 40 hours a week I wear it. I work outside in a commonly rainy area, and it's not uncommon for the watch to get wet. I've had it for a couple months or so now, and it really works great!
Honestly all of the complaints I have about it can be fixed solely by looking at the price.
The viewing angle isn't fantastic - it's a $13 watch.
It does lose a little bit of time (a second or two within a week, maybe) - it's a $13 watch.
The band is a bit uncomfortable (though it does hold very well, and has lots of size options) - it's a $13 watch.
Those are minor things. Here's the good stuff.
-Super easy to read
-Very easy to use and set
-Multiple features
-Is genuinely waterproof. I haven't held it underwater, or anything, but for what I would consider 'average' use, it is perfectly waterproof.
-Has an adjustable band that doesn't fall off
-Fairly tough. I don't treat mine very well and it's held up perfectly fine so far.
-It's cheap!

Cheap Gshock replacement, good value
For $13 this is a steal. It's essentially a casio illuminator w larger bright dial, press once for 5 sec of light then goes dark. Date, time (12 and 24hr), stop watch. The basics, all I needed. A+
Edit: updated the waterproofing is non-existent. It's not even water resistant so treat accordingly don't bring into the shower. The face plastic cracked on me from moderate use, still legible and since I don't test it with water not an issue. The buttons are very sensitive so activities like lifting can cause the bottom left button to depress and switch to stopwatch, or engage the stopwatch.
After over a year use I still rank this as a good value. It does the one thing I wish Casio would do is improve light illumination time. The buttons depress easier than Casio's which is a bonus imo, but can be aggravating to some. The water resistance doesn't exist so purchase accordingly.

Great watch, wristband wears out after a while. Uses a Skmei 1251 band.
Watch is reliable, doesn't drift in time too much, very efficient on battery, has gotten complimented on the look a few times and has a nice user interface. It's also great to be able to see the date without pressing any buttons.
The band has fatigued and snapped after many months of putting on and taking off the watch, but If you'd like to find a replacement band, search for Skmei 1251 wristbands.

Inexpensive sports watch that was easy to set up and works well.
I have had this watch for a few days. The included instructions were very basic, but I figured out how to set everything up pretty easily. The watch band is pretty adjustable, fits my fairly wide wrists very well. For the price, about half the cost of the name brand very similar watch it replaced, the watch works well, I am very pleased.

This is a great watch for the price!
I purchased this watch to use mostly down at my cabin. It is well-made, the functions are easy to use, and it has withstood all the abuse I’ve put it through. I wear this while hunting, cutting firewood, riding ATVs, and just running around the timber. If I destroy this watch in six months, it will be well worth the money I paid for it, but I don’t think that’s going happen. It’s stylish enough to wear to the office and just going out. If you’re looking for an every day watch, you’re not worried about destroying, this is the one to get.
