As stated in the video, the tank is doing pretty solid despite the issue with the RODI system. So far, the only bad effects have been a cyano outbreak. The ICP test revealed that magnesium and calcium are low along with iron potassium and a few other minor trace elements. Silicates are also high. All the RODI cartridges and carbon block have been replaced except for the membrane. 2 40 gallon water changes have been done in the past two weeks. Triden is also up and running. Will be getting more fish to increase bio load soon.
