Spencer Heaton Posted September 23, 2022 Share Posted September 23, 2022 Hi Everyone, I was forced to move a month or so ago and the new house has a water softener and filtration system that includes a dechlorinater and a membrane filter similar to an RO system. I had a plumber install a new sink for me with the cold source taken from before the softener/filter system and the hot water from the hotwater tank which unfortunately gets its source from the softener before it is heated. I have been mixing hot and cold water and doing my water changes as normal and for the last few weeks and I have lost some fish (mostly my apistos) and a few chain loaches. (I have 12 tanks) Most of the fish including the Rams seem to be doing ok but a couple of other apisto have turned dark over the last few weeks (different species than the ones that died). Also not a lot of my plants seem to be doing well and I had a huge jungle of Val which has slowing just died off. So, I just did some water test and here are my results: Mix of hot and cold: 0ppm Ammonia, nitrate, nitrite PH of approx 7.6 to 7.8 GH of 17 drops so ~200-400ppm KH of 17 drops so ~200-400ppm TDS of ~480ppm Just HOT water (softened): 0ppm Ammonia, nitrate, nitrite PH of approx 7.2 to 7.4 GH of 1 drop so ~0-50ppm KH of 17 drops so ~200-400ppm TDS of ~680ppm Just COLD water (city): 0ppm Ammonia, nitrate, nitrite PH of approx 7.8 to 8.0 GH of 22 drops so ~200-400ppm KH of 17 drops so ~200-400ppm TDS of ~300ppm I know that the majority of the TDS is the the sodium from the softener. I also believe this may be the source of the issue with a lot of my live plant issues. However, I am also wondering if I should be adding minerals back to the water (using one of those trace products) since it looks like some or most of the TDS is KH related so I am thinking there is not enough trace elements left in the water after it has been filtered through the system even though I am mixing with the city water. Also l am thinking I may need add an RODI unit to the mix but it would need to be connected to the city water (cold) I assume so that will not help remove all the sodium from the mix either. Any advise anyone can give me would be great!!!! I will attach some pics to help illustrate what I am referring to. Thanks, Spencer 1 Link to comment Share on other sites More sharing options...
