This move is simply because AF supply is inconsistant in my country. Also, I an unhappy that there is a lot of precipitations of probably trace elements such as Iron. AF spread their trace elements among the three dosing parts. This however does not seem to prevent some precipitations. Having said that my tank is doing fine with lots of fish lps and now a few sps. I work w/o water changes. I do sapplement TM trace elements with the dosing. TM has all the t. elements in the 3rd NaCl-less dosing part. I dose about 75 +/- 10 ml daily so i added A & K elements so that 4 ml of each are dosed each day. Also added rodi water to the 3rd container to keep the ratio. Any further advice or tips to share expirience using the TM "classic" Balling system?
