Shakeb1000 Posted December 26, 2018 Share Posted December 26, 2018 Hello everyone, so i started cycling my tank roughly 2 days ago and I realized the water I used to mix my saltwater wasn’t RO/DI or Distilled. It was just filtered Nestle Water. I want to completely remove all the Water in the tank and replace it with Saltwater o get from my local fish store. I just wanna make sure it’s okay if I do that, meaning nothing will go wrong? Will there still be salt left in the sand that might raise the salinity when I add the new water? I’m just cautious on if I can do such a thing or not. Let me know if you’ve ever done a 100% water change or have any ideas Quote Link to comment
specore Posted December 26, 2018 Share Posted December 26, 2018 I wouldn't worry about it. You will be doing multiple water changes before you add any livestock anyways, and as long as you don't keep using the Nestle water you won't have any issues. The potential issues from the added minerals would be from a buildup in mineral concentrations over time as you top off, etc. 1 Quote Link to comment
Clown79 Posted December 26, 2018 Share Posted December 26, 2018 I wouldn't bother either. I would just continue the cycle. Start using distilled or rodi for evap top ups and when your cycle is done start doing your waterchanges with distilled/rodi. Even lfs water can be bad, some don't change filters often enough or it's just RO water not rodi. it should be tested if one chooses to go that route. 1 Quote Link to comment

Good advice. I've seen LFS water running 300 TDS! RO/DI water should always be checked with a TDS meter, regardless of whether you make it yourself or buyit. 1 Quote Link to comment

A lfs once tried to tell me the sulphur smell coming out of their salted water was fine and not to worry about it. I skipped that week because there was no way of testing the saltwater. Sure enough, a week later I was greeted with "you came at the perfect time, we just upgraded our water filtration" That's when I started buying rodi only and mixing at home so that I could test the water and shortly after I bought my own rodi unit. 2 Quote Link to comment

Guess something in their system must have been so old it had started leaching back into the water 🙂 Quote Link to comment
Boggers Posted December 26, 2018 Share Posted December 26, 2018 You you fail to change out your DI, it will leach back into the water. I wouldn't say there is a need for the 100% change either, but yes I do it with my 1G tank every week or 2. Quote Link to comment
