Fast-acting, accurate, easy-to-read test strips test the ammonia level in your fresh or saltwater aquarium. Use on their own, or as refills for your Mardel master Test Kit (also available, sold separately).

Mardel's 5-in-1dip & read test strips test fresh or saltwater for five important water quality indicators: pH, hardness, alkalinity, nitrite and nitrate. Use these strips on their own, or as refills for your Mardel Master Test Kit (also available, sold separately).

Neutral Regulator is the fast, easy way to reach a pH level of 7.0 in your freshwater aquarium. It adjust pH up or down and helps to maintain it at a consistent level.

Tidy Tank(tm) contains a specifically developed sludge removing bacteria used to remove organic debris from aquarium gravel, filters, tubing, etc. Tidy Tank contains billions of heterotrophic bacteria. These Bacillus species bacteria rapidly consume carbohydrates, proteins, starches, fats and cellulose that build up in aquariums as the result of feeding, fish waste, decaying plant matter and other organics. As well as eliminating unsightly sludge from the aquarium, these bacteria will also reduce odors that are produced as a result of organic decay. Add two teaspoons for every 10 gallons of water directly into the water. Repeat dosage after 24 hours. Repeat the above steps bi-weekly or when wanting to remove visible sludge. To increase effectiveness, add directly into filter media, particularly activated carbon. Tidy Tank contains no hazardous chemicals or bacteria.

The LiveMeter Master Test Kit in-tank meter takes test strip water monitoring technology into your aquarium, making it even eaiser to maintain healthy water quality. The kit helps you maintain healthy water by constantly monitoring pH, ammonia, and temperature, providing an immediate indication when harmful changes occur.

Stress Guard reduces stress and ammonia toxicity when handling or transporting fish. It binds to exposed protein in wounds to promote healing of injured fish and reduce primary or secondary infection. Will not clog filtration as some slime coat products can.

This in-tank pH monitor takes test strip water monitoring into your aquarium, making it easier to maintain healthy water quality. The simple and precise device allows you to monitor pH values at-a-glance. The patent pending technology ensures accurate apH values.To use, simply attach to the inside of your aquarium using the included suction cup. Once fully wet (1-2 hours), LivepH responds to pH changes in minutes. Compare the active membrane to the color reference blocks to determine pH level.For best results, replace each LivepH every 4-6 weeks. A pH test is most accurate in correctly buffered water.Measures 3 3/4""L x 1 1/2""W. For freshwater use.
