Important information

Directions

 

Directions: 1. Attach the suction cups (included) to the double suction mounting bracket. Slide bracket over heater to position indicated. 2. Place heater in aquarium by firmly pressing suction ends against wall surface. The three-position viewing window allows you to view the temperature setting from three possible angles, simply turn the heater until it locks into the best viewing position. Note: Choose an algae free location with adequate circulation. This ensures even heat distribution and optimum operation. No part of the heater housing should contact aquarium gravel, rocks or decorations. 3. Wait at least 15 minutes before plugging in your heater. The on off indicator light will confirm that the power is on. Note: Before plugging in heater, create a drip loop: to prevent water from reaching receptacle. 4. Select the desired temperature. Turn the "Click Set" temp select dial until the point of the red light on the thermometer scale reaches the correct setting. Most tropical fish like 78*F - 81*F water. Note: It is recommended to use a tank cover to prevent water temperature variances to heat loss. Both can impair heater performance, create a hazardous environment for the fish.

Great fit, functional, most comfortable shorts!
Size: 30, Color: Anthracite Camo
These are my go-to shorts, I now have five pair in different camo colors! I suggest one waist size smaller than you normally wear, (I buy a 30 instead of a 32, because they stretch and would be too sloppy if I purchased my regular size). The large open slotted pocket on the left, behind the Velcro flap pocket, is perfect for a normal sized cell phone. Plenty of utility pockets for EDC. Since these stretch slightly to accommodate movement and sitting, they are extremely comfortable. Also, my wife says they are good looking on me, so that gets an extra star!

Love the material!
Size: Large, Color: Black
Very soft and beautiful material. The size was perfect. It works well for layering and can also be dressed up. It is not clingy at all. The quality is great.

Worked well for my needs!
Size: X-Large, Color: Black
Nice thick material. I think these could be workout shirts or regular day attire. Soft, wash well, nice stretch, and arm pit gaps aren’t a so wide they look silly or sloppy. Good value for the money. True to size as well.

Great Fit & Great Price
Size: 3X-Large, Color: White
The material is very nice and soft but not clingy. It’s light weight but not see through in both white and peach. This tank fits true to size and has no gaps under the arm like some other tanks I’ve tried. It’s a perfect layering piece under shirts and sweaters. Very affordable and well made. I’m a plus size lady who is happy with the fit.
