Ph digital

Note: The new digital tester shouldn't need to be adjusted. When you turn on the tester, you may find the measured value is not accurate and unstable, it's normal phenomenon. Put the digital tester in the liquid that you want to test about 1 minute and you can read the PH. If you find it not accurate, use the Calibration Adjustment Screwdriver (including) to adjust the adjustment trimmer.

Features: A PH meter is an electronic device used for measuring the pH which is either the concentration of Hydrogen ions in an aqueous solution or the activity of the Hydrogen ions in an aqueous solution. The pH will indicate if the solution is acidic or basic, but is not a measure of acidity or alkalinity. -PH meters work in liquids though special probes are sometimes used to measure the pH of semi-solid substances. External power supply can measure continuously for 24 hours to avoid reading errors due to low battery power. Digital display for easy reading.

Description Marine Buffer® will safely raise marine pH to 8.3. It will not raise pH above 8.3 even if inadvertently overdosed. Marine Buffer® is a blended product and is not just sodium bicarbonate or sodium carbonate, commonly sold as a substitute. Such products can raise pH to dangerous levels if not used properly. Marine Buffer® contains sodium, magnesium, calcium, strontium, and potassium salts of carbonate, bicarbonate, chloride, sulfate, and borate. Use Seachem's MultiTest ™: Marine pH & Alkalinity to check pH and total alkalinity. Use Marine Trace™ to restore the proper level of trace and feed NutriDiet® Marine Flakes for thriving, healthy saltwater fish. Total Alkalinity is a measurement of three main ions: carbonate, bicarbonate, and borate. In saltwater, bicarbonate drives the pH toward 7.8, carbonate drives pH toward 9.1, and borate toward 9.5 or more. Because of the chemistry of buffering systems, the closer you get the pH to the pK of a buffering system, the harder it is for the pH to shift. So, if you blend a buffer so that the combined product drives the pH toward 8.3, then the more you use, the more stable the pH becomes. That is the principle behind Marine Buffer™. It is a blended buffer that drives and holds your pH at 8.3 because of the blend. The catch to this seemingly simple solution is that most salt mixes contain substantial amounts of bicarbonate salts. This shifts the pK of the buffering system further towards 7.8, and a buffer that shoots for 8.3 will never quite get there. Thus, the pK of Marine Buffer is actually slightly higher than 8.3 in order to combat the influx of bicarbonate at every water change. Marine Buffer™ was the first buffer on the market which contained borate salts (which make a saltwater buffering system much more stable), and Marine Buffer™ remains the most effective pH buffer on the market for marine aquaria. Directions Add 5 g (1 level teaspoon) for each 80 L (20 US gallons). For precise dosing, use the Seachem Digital Spoon Scale. Dissolve in at least one cup of freshwater. This dose will also raise alkalinity by about 1 meq/L. Add daily until pH stabilizes at 8.3. This will take from a day to a week, depending on original pH and alkalinity. Thereafter, use biweekly or monthly to maintain a pH of 8.3. If this practice is not adequate, then overstocking, overfeeding, or other poor management practice should be sought as a likely cause. In ionically balanced marine water, Marine Buffer® produces little precipitate or cloudiness. If an extensive precipitate forms upon addition of Marine Buffer® that does not dissolve within ~15 minutes, then poor ionic balance was present. A water change should be initiated when convenient before further use of the product. Effectiveness improves with continued use. Do not directly mix with any calcium, magnesium, or strontium supplement. Rebel Pets Seachem Marine Buffer 250g

Description Neutral Regulator® adjusts pH to neutral (pH 7.0) from either a low or high pH and maintains it there. It softens water by precipitating calcium and magnesium while removing any chlorine, chloramine, and detoxifying ammonia. The use of Neutral Regulator® makes other conditioning unnecessary. To lower pH below 7.0 use Neutral Regulator® with Acid Regulator (or Discus Buffer®). To raise pH above 7.0 use with Alkaline Regulator. All of these products will enhance and stabilize the freshwater aquarium environment. For further freshwater environment enhancement, use Fresh Trace to restore the proper level of trace elements and feed NutriDiet® Tropical Flakes for thriving, healthy freshwater community fish. Directions Use 5 g (1 level teaspoon) for every 4080 L (1020 US gallons) once or twice a month (or as necessary to maintain a pH of 7.0.) Neutral Regulator® may be be initially used daily in cases of high alkalinity until 7.0 is established. It may be added directly to the aquarium at any time. Ideally, it should be used when adding or changing water by dissolving in the replacement water. For precise dosing, use the Seachem Digital Spoon Scale. Contains phosphate buffers and conditioning agents. Safe for all freshwater fish acclimated to neutral pH.

Ammonia and Chlorine and Chloramines remover.   Dosage: 5 g per 1 kg biomass per day (about a teaspoon)   One teaspoon per day in the quarantine pond can do all the difference. Used for more than 10 years at koi shows by us for water quality control and save water and labour. Please contact us for more information on how to use for shows. Assist biofilter while maturing A handy product to have available for first aid in a case of a crisis ----- The active ingredient in ChlorAm-X is sodium hydroxymethanesulfonate, HOCH 2 SO 3 Na (or sodium formaldehydebisulfite for some) Water treated with ClorAm-X will give false (high), off-scale readings with ammonia test kits that use Nessler's reagents. Water treated with ClorAm-X is compatible with most salicylate and phenol/hypochlorite test kits. I have tested a number of available kits (including my Hanna ammonia digital colorimeter) and found the Tetra kit the only one that remained accurate. The dry-tab test from Interpet was surprisingly inaccurate even without Chloram-X. Water treated with ClorAm-X is compatible with all known nitrite and low-range nitrate test kits. Water treated with ClorAm-X is incompatible with Winkler and modified Winkler dissolved oxygen (DO) test kits. These kits will give false, low, or zero, readings. However, water treated with ClorAm-X is compatible with indigo/carmine dissolved oxygen test kits and with dissolved oxygen meters. Be aware of pH instability at low alkalinity (“Overdosing” We noticed that a relative high dose of Chloram-X resulted in a undetermined or difficult to read colour developed during testing for ammonia.
