AMMONIA ALERT Seachem Ammonia Alert™
1 YEAR MONITOR
Ammonia Alert™ is an innovative color device for continuously detecting and monitoring toxic free ammonia. A sensor changes reversibly from yellow to green to blue, relative to the ammonia concentration. No test kits, chemicals, or procedures are needed. The device detects less than 0.05 mg/L (ppm) free ammonia and alerts you to the #1 ki... — FREE shipping when ordering $75 or more of qualifying items....more.

AQUA TEST CA- CALCIUM TEST KIT 12/CS Elos Ca - Test Kit
Calcium is the primary building block of corals, clams, calcareous algae and many other organism that we grow in our aquarium. Without adequate supplies of calcium these organism will not flourish and will eventually waste away and die.
The ideal value of Calcium in the aquarium is:
For the marine aquarium 450 mg/L.
For the planted freshwater aqua... This item is sold individually....more.
AQUA TEST MG-MAGNESIUM TEST KIT 12/CS Elos Mg - Test Kit
Magnesium (Mg) is present in a high quantity (1.300/1.350 ppm) in natural seawater. Contrary to its (not only quantitative) significance, this element was ignored as an important parameter of the marine aquarium for a long time.
In contrast of what we know today, Magnesium creates a remarkable improvement in the growth of calcareous algae and also has a posit... This item is sold individually....more.
AQUA TEST NH4 AMMONIA TEST KIT 12/CS Elos NH4 - Test Kit
Ammonia is the most lethal form of inorganic nitrogen produced in aquarium water. The major source of ammonia in a well run aquarium, is from solid waste of fish and invertebrates, uneaten food, decaiyng leaves of plants. Nature comes to our rescue as there are specialized bacteria (Nitrosomonas species) that “eat” ammonia, and strip away the hydrogen atoms. By... This item is sold individually....more.
AQUA TEST NO2 NITRITE TEST KIT 12/CS Elos No2 - Test Kit
The activity of the bio-filter in the aquarium system can be divided in mineralization and nitrification. The products of the mineralization process are ammonia and organic acids. The next step of decomposition is the oxidation (nitrification) of ammonia and ammonium to Nitrate (NO2). Nitrate has a toxic effect on fish because it oxidizes hemo...

AQUA TEST NO3 NITRATE TEST KIT 12/CS Elos No3 - Test Kit
The biological filtration is a method that uses naturally occurring nitrifying bacteria to detoxify nitrogenous wastes. One type of bacteria (Nitrosomonas spp.) converts ammonia to nitrite while another naturally occurring bacteria (Nitrobacter spp.) converts the nitrite into a far less harmful form of nitrogen waste: nitrate.
Nitrate is the final stage of t... This item is sold individually....more.
AQUA TEST PHD PH TEST KIT 12/CS Elos pH Fresh Water - Test Kit
The activity of the bio-filter in the aquarium system can be divided in mineralization and nitrification.
The product of the mineralization process are ammonia and organic acids. The next step of decomposition is the oxidation (nitrification) of ammonia and ammonium to Nitrite (NO2).

AQUA TEST PHM PH TEST KIT MARINE 12/CS Elos pH Marine - Test Kit
The pH value or acid value indicates how acidic or alkaline water is. It is a measure of the concentration of the acidic or alkaline components in a hydrous solution.
The salt water aquarium pH-value is considered between 8.1 and 8.4 pH which is the value found in natural seawater.
Many organisms will react with high sensitivity to very small varia... Note: Calibration Buffer Solutions are available separately.This item is sold individually....more.
AQUA TEST PO4 PHOSPATE TEST KIT 12/CS Elos PO4 - Test Kit
Phosphate (PO4) build up in the tank appears to be a fairly common problem in freshwater and saltwater aquariums. They are present in most tap water supplies, they are also introduced to aquarium water through fish waste,
uneaten fish food, and decaying plant and invertebrate material.
Hobbyist end up with rising levels of PO4, leading to the appearance of ... This item is sold individually....more.
