When I set the tank up last fall… I was using non softened water in 5 gallon buckets and leaving it in the sunlight to warm up. I had a couple fish die, but nothing drastic.
Then cold weather hit and I had to start using hot water for water changes. Then it seems that more fish were dying. So, I had my water tested and all levels were perfect, except for the hardness. They knew the second they did the test that I used a water softener. And as they said… it is doing a GREAT job. There was literally NO hardness to the water. This is the only reason I am using the salt and buffer… to get the GH and KH up to bearable levels. All other levels are perfect.
So, I don’t think that just not adding anything is a good idea.
Things got better, but I still have fish turn up doing this same damn thing. Hard breathing, usually with a bloated stomach, but not always. They also stop eating.
Way back I tossed all the foods I had, except for the Omega One Super Veggie and the NLS. About a month ago I added the NLS Thera A to the diet. I didn’t notice much of a difference. I really do not believe that I over feed.
I have had many many fish tanks and never had any issues like this before. Usually my fish thrive and I have no issues at all.
My tanks go….
140 gallon – mixed Africans, no peacocks
85 gallon – mostly all peacocks and some calvus
40 gallon – Albus and Ruby Peacocks (soon to split the two up into another 40 gallon tank)
20 gallon – Muzi Compressiceps, fry. The Albus were in here for months. No issues.
20 gallon – Ruby Green Hap fry. Months. No issues.
The 85 gallon is where I have had most of the trouble. Now recently a couple in the 140 gallon got “it”
I really would like to set up some water storage tanks that I can fill with pre-softened water. If I do that, I will not need to add much of anything to the water. I just need to figure out how to heat the water.
