That's the one I use, great meter. TDS is basically the accumulation of everything, you'll see it rise throughout the week as you add ferts and if you have rocks that leach, they'll impact it too as will decaying plant matter. I raise TDS of RODI water by remineralizing - adding back in Mg and Ca for GH, and sodium bicarbonate for KH. This generally brings my TDS up near 200 from 0. The way to lower your TDS if it is rising through the week is simply doing a water change. The need to test for it depends on what you're keeping. For sensitive fish and shrimp, it's not a bad idea to check TDS occasionally.

Sounds like you have some more research to do still. TDS is everything that is dissolved in the water. There is not necessarily a need to "correct" anything when it comes to TDS. If you have a reading of say 100 TDS in your tank and I have the same TDS reading of 100 that does not mean we have the same things in our water. We just both happen to have roughly the same amount of stuff in the water. That could be because one of us adds fertilizers and the other doesnt. It could be that one of us has not done a water change in a long time; or it could mean we just did one 5 minutes ago.

TDS tells you whether or not you have "stuff" in your water. "Stuff" is not always a bad thing though. The next step is to figure out what it is that is actually dissolved in the water; and then you might need to try and make a correction one way or another.

As far as measuring, you want a TDS meter. Name brands shouldn't matter much. Most of the affordable TDS meters you'll see on places like amazon or online auctions are no name things likely made in China. But the work well enough for our purposes.

As always thanks for the replies and your right can't do to much research.Just to clarify my situation.I have a 90 gal. Discus tank that has been up for a little over a year and thanks to discus Paul and a few others I may be on the road to sucess after a fer expensive failures.changes I have made include removing about 80% of the plants,cutting back to once a week on the ferts,doing water changes every other day and raising the temp to 84,since those changes I have had a dramatic change in the health of my fish,I now have 7 5-51/2inch Discus doing great,my thing with the TDS was that the one issue I have or may be imagining is water clarity and I read that excess TDS can have an effect but with every other day water changes I now feel that is not the issue.I have been told by many that I am paranoid and obsessed with this tank because they say it is clear as can be[GUILTY] but my 40 and 45 are so clear that if the water was not moving you would think they were empty.I have a eheim skimmer coming because one issue is an oily film I can't get rid of even with the spray bar pointing up and that may be what I am seeing I don't think it is the light so will have to wait and see...

TDS is dissolved stuff, if you have bits in your water you can see they are probably suspended particles not dissolved. Using some fine filter floss may help get that last little bit of extra clarity.
