"I perform and recommend to others that they do regular water changes, not as a method of maintaining iodine concentrations, but in an effort to dilute the myriad noxious compounds produced in reef aquariums that are not easily tracked by standard test kits (Borneman, 2003). As there are no accurate means of measuring all the forms iodine may take in aquaria (Holmes-Farley, 2003), and I am adamantly against adding anything to my display that cannot be measured accurately and consistently, I don't use iodine and don't encourage its use by most hobbyists" "So what if the measured nitrate level is consistently low or nonexistent? What does that mean? Well, it means just simply what the test says, and that by itself implies nothing else about the tank's water conditions. Countless compounds that we cannot measure are constantly being produced in our aquariums (Borneman, 2003.) Just because the water quality appears to be in the proper ranges on standard aquarium test kits does not necessarily mean that the water is in perfect condition or that there are no foreign or deleterious dissolved compounds in the water" Någonting att tänka över när man hela tiden testar sitt akvarium för att se om "värdena" är bra eller om man bör tillsätta mera spårämnen vid sidan om. Blanda och byt salt skall väl vara de korrekta sättet för att exportera bort skit och ersätta det med välbalanserat nytt saltvatten.
