Description

Most water problems are invisible to the eye. Quickly measure and modify the six aquarium levels that are most important to the health of your freshwater fish with the API FRESHWATER MASTER TEST KIT. To stay healthy and thrive, fish need properly balanced levels of ammonia, pH, high range pH, nitrite and nitrate. These levels can change rapidly and create harmful conditions when fish waste, uneaten food or other organic matter accumulate, or when untreated water is added. If left uncorrected, all of these can be harmful or even fatal to fish, with consequences such as reduction of oxygen, increase in stress and higher risk of disease. The API FRESHWATER MASTER TEST KIT measures these six parameters with scientific accuracy and provides professional results. It comes with four glass test tubes, a holding tray, test tube rack and computer calibrated, laminated color card. Just fill the test tubes, add the test drops and compare results to the color card. Then follow the recommendations on the card if action is required. With API Aquarium products, its easy to keep a beautiful saltwater, freshwater or reef aquarium. For over 50 years, API has been creating innovative, research-driven solutions that make it easier to care for your fish and aquarium. API Aquarium Treatment Supplies are designed to work in conjunction with each other to provide best results to control algae, promote healthy bacterial growth and help control and cure fish diseases and conditions such as ich and fin rot.

5. Glass Co2 Drop Checker with 4dkh/PH Solution | Quickest, Most Accurate & Easiest to Use | NilocG Aquatics | Glass Co2 Drop Checker with 4dKH/Ph Reagent Most Accurate Monitoring of Your Co2 Levels

Feature

WHY SHOULD YOU PURCHASE THIS DROP CHECKER AND INDICATOR SOLUTION: The biggest reason is that it comes with 4dKH fluid and ph reagent PRE-MIXED. If you arent using 4dkh fluid your reading is very unlikely to be accurate. Second this drop checker is very easy to use and fill. No need for syringes and other items, the indicator solution comes with a flip top bottle for extremely easy use.
IMPORTANT- MUST READ- It is very important to use 4dkh fluid and ph reagent in your Co2 drop checker. If your drop checker directs you to use tank water then it will not be accurate and you will not have a good idea of what the actual co2 levels are. If your co2 drop checker doesnt list 4dkh fluid then assume you dont have it. Its a must have for optimum accuracy!!!!!!!
Highest Quality Co2 Drop Checker With 4dKH/PH solution. Monitoring co2 levels in your planted aquarium is very important for the health of your plants and fish. This kit is complete with everything that you will need. It includes: High quality drop checker, suction cup, 60ml bottle of 4dkh/ph reagent solution.
EXTREMELY EASY TO USE CO2 DROP CHECKER- To use simply fill the drop checker half way with the Co2 Indicator Solution. Place suction cup on the drop checker and place in your planted tank. Wait 2 hours to read Co2 levels.
HOW TO READ CO2 DROP CHECKER- When your co2 is off the drop checker solution will be a deep blue color. After co2 has been on for around 2 hours you should notice the color change. Optimal co2 concentration will be at 30ppm which will be a green-light green color. If it remains blue your co2 is too low. If the color turns yellow then your levels are too high and may harm your fish. USE THE COLOR CHART ON THE SIDE OF THE CO2 INDICATOR SOLUTION or ON THE PRODUCT INSERT-

8. Rhinox DIY Pressurized CO2 System, CO2 Generator Kit, Includes Caps, Valves, 3-Way Connector, Tubing and Pressure Gauge, Creates a Healthy Underwater Habitat for Aquatic Pets and Plant

Feature

INCLUDES EQUIPMENT NEEDED TO DO IT YOURSELF --- In order to build an effective and efficient pressurized CO2 system, there are a few pieces of equipment that are absolutely necessary. The SunGrow DIY CO2 Generator Set includes two caps (that perfectly fit common PET plastic bottles), needle valve, check valve, a pressure gauge, a 3-way connector and 6 feet of 6mm tubing. You simply have to use 2 carbonated beverage bottles, a reaction material and connect it to a diffuser.
GENERATES ESSENTIAL CO2 FOR A HEALTHY HABITAT --- Fish and aquatic pets release cO2 when they take in the dissolved oxygen from the aquarium water and plants absorb that co2. Carbon dioxide is essential to the photosynthesis process and sometimes fish alone do not generate enough Co2. A pressurized DIY CO2 system adds the needed gas to your water.
COST-EFFECTIVE & SAFE TO USE --- Instead of spending hundreds of dollars on expensive CO2 diffuser set-ups, save money by creating your own do-it-yourself CO2 generator. The basic principle behind the pressurized CO2 diffuser kit is to create a continuous supply of pure carbon dioxide by causing two different liquids to create with one another. The DIY solution is a cost-effective and satisfying way to add essential CO2 into your aquarium water.
EASY TO READ, SPECIALIZED PRESSURE GAUGE --- The SunGrow DIY CO2 Generator Set comes complete with a high-quality, specialized pressure gauge. The metal pressure gauge clearly shows the level of CO2 gas on a scale which indicates a safe area. An accurate CO2 reading gives you the chance to make adjustments or relieve pressure before there are any negative effects on your aquarium inhabitants.
CREATE HOMEMADE DRINKS AS AN ADDED BONUS --- Obviously the DIY Pressurized CO2 Kit is designed to add and control the amount of CO2 available to your fish and plants, but there is a bonus to creating your own CO2 generator. Instead of using baking soda or vinegar as your reaction material, use yeast and grape juice (or yeast and malted barley) to create homemade wine and beer.
