Is salinity a separate measurement here or just a TDS approximation? Using for a salt water reef tank with other minerals (like calcium, etc.).

Just an approximation. The basic measurement of this instrument is "Specific Conductance" (also called "Conductivity"). It is measured in micro-mhos per centimeter. The unit reads out in equivalent parts per million (ppm) of KCl or NaCl. You would need to determine experimentally the relationship between specific conductance and the ppm of your particular salt solution. Hope this helps.

There are 3 different reference levels(calculations) that this meter can do. The meter is accurate within what it cam measure. Read the manual on what the meter uses and what uther things can throw off the readings. I have found to to be pretty good meter myself.

Chemicals used in the saltwater version are just pool salt. It comes in 40 pound bags. You also will need a certain fine grain sand (this goes inside your filter).

To measure salinity in a fish tank or pool, you'll need a different kind of hydrometer. Search for Red Sea Hydrometer on Amazon (pet/fish tank supplies), and you'll get the idea of the kind you need.

The TDS of my tap water is 430ppm; all those minerals would surely shorten the lifespan and effectiveness of this unit. Hence I use RO water [I have a unit which I normally use for my aquariums] which has a TDS of below 10ppm. You can buy distilled water although not sure how costly that is in the longrun.

While many people use distilled water, it is highly recommended to use a calibration fluid that is set at 35.0 PSU. The reason for this is, there is a high margin of error when calibrating accuracy to a figure that is far from target. If you do not have calibration solution, you can make your own. When trying to make a calibration solution of 35.0psu, it means that the sodium chloride concentration is 3.65 (weight %). What that means is, for every 3.65 grams of sodium chloride (morton's iodized salt) there needs to be 96.35 grams of purified fresh water (distilled is ideal). To increase accuracy of the solution, my recommendation is to mix it in a greater multiple of the above amounts, i.e. 79.3g of salt mixed with 2104g of distilled water. That solution should be just about 35.0 PSU, or target saltwater salinity.

The meter measures Total Dissolved Solids (TDS) in your water. Salt is one component of TDS, but the meter does not measure each component. It measures the total TDS

You need a filter system and sand is the way to go for that , much better than paper filter. I wouldn't think that this would make enough difference to justify the cost over you salt water generator now. I am converting from chlorine to salt water.

While I haven't used Sea 90 with fish, it is water soluble and very close to the mineral salts I have used in ornamental aquariums. I would do a test in an aquarium tank with a few fish first to make sure there are no ill effects in the fish.

Not sure what your question is. I use this instrument to test salt level in my aquarium. Too much salt add fresh water, too little do a water change. If mixing your own water make sure to use ro/di water and test for salt levels.

I am not sure if this can be used for salt water pool check. I recommend searching for "salt water test strips". I think you would want to check for sodium chloride levels which this product does not check for.

I don't see why you couldn't use it for saltwater. Should work as it is inert. I'm not a saltie- expert though, mind you.There are some substrates out there that will buffer the water better for saltwater. Saltwater requires a higher pH and a higher GH/KH. Using an inert substrate won't hurt your fish or alter the chemistry of the water- but won't provide any buffering for pH swings etc. As fish "pee" and "life-happens" the pH of the water will change slightly between water changes. You will usually be better off for saltwater with a buffered substrate... but this wouldn't be bad. I don't see why you couldn't use it for saltwater. Should work as it is inert.

The Digital-Aid Water Purity Test Meter from Simply Natural Life is convenient, well-packaged, and priced right. It supplies a choice of TDS of Conductivity at the press of a SHIFT button, and also temperature in either degrees F of C. The instrument uses the temperature measurement to help accurately calculate TDS and Conductivity. I tested accuracy using my citt water and mt R-O water. Today, city water measures 335 ppm TDS, and the R-O reads 23. My city specifies TDS as "less than 500 ppm," and the R-O reading shows that my 5-year-old membrane is still working.

The directions are on the bottle when you receive it. It will be a dose of 5ml per each 20 gallons. But I would also recommend Seachem's "Trace elements" to go with this. In my experience, just adding the CO2 did not give me good plant growth. If you are not also using a nutrient supplement with this, your results will be limited. I also used a potassium supplement, and using all three of these together brought my nearly dead, yellowed plants back to life within a week, and they are doing very well, now. I don't know how much you know about any of this, so forgive me if I seem to over-explain all of this. One last thing that I would add is that if you are having problems growing plants in your aquarium, the proper ph is very important for some plants. Because most cities/towns put chlorine in the water to kill harmful bacteria, the ph of your tap water will be slightly alkaline. If you are setting up a salt water tank, that's not too bad. But a freshwater tank will need to be slightly acidic to neutral in the ph. This is important. I hope this helps, and yes, the flourish excel works very well if you use it with the other supplements which I mentioned.

I have a freshwater tank so 'I' can't say for sure about saltwater .. My daughter has a saltwater tank and said that removing water is the only way to 'lose' salt percentages ..

I'm not sure, it tests chlorine, ph, and alkalinity. If that's all you need for a salt pool, the yes.

Works great in chlorine pool, not sure about salt water, when actually working.

Not to my knowledge in a true salt pool, only in a SWG pool. They provide great reading for everything other than salt in your pool. Funny, that you asked since I'm converting to a SWG in Spring 2015 and was wondering the same thing myself. Personally, a SWG is the same as a Chlorine chemical additive pool, just does it different, so readings should be the same using these. Only thing missing is Salt Content which I plan on using a separate test for. It covers all the areas beside lets us see the CYA level, Cyanuric Acid - Conditioner, or Stabilizer, is since... SWG pools generate only chlorine. Hope this helped. Not to my knowledge in a true salt pool, only in a SWG pool. They provide great reading for everything other than salt in your pool.
