It will help to ask the staff at the local fish store about the water quality from the tap. pH and hardness. Than try to match the fish according to your water and not the other way around. My kids started a tank more than a year ago. They got the fish based on color and price and the staff did not discourage them from getting whatever they wanted. Did not mention schooling, territorial behaviour, aggressiveness, compatibility between them or water demands. Like if they want 10 male bettas, they will get them. Anyway, 6 months later I was left with 5 fish. Even the guppies died in that tank. Turned out, my water was soft and acidic and the 5 fish left were a pair of angels and three tetra (fish found in Amazon where the water is soft and acidic)

Out of the tap I think it's acidic and soft, the pH hasn't changed much at all in the tank no matter what. But even after using dechlorinator the CI is still not quite where it should be. I guess they add a lot since it's desalinated water.

I'm just gonna let the tank run for the next 3 days as I'm away for work then see what I have when I get back. Changed the water yesterday so it should be ok for a few days. Don't want to change it too much anyway!

Today's testing (14hrs after major water change)

CI: 0 (finally! I think perhaps because I used Prime instead of the other conditioner I had)
pH: a bit higher at 6.6
KH: >3'd
GH: >4'd
No3: 0.5 (barely coloured)
No2: 0 (yay!)
Ammonia: Still the lowest reading at "less than" 0.05- same as always. This was despite putting a pinch or so of fish food in last night.

So, in my newbie experience, it SEEMS the tank may be on its way to getting cycled. But without ammonia, I cannot be sure! Lol... if I stil lget 0 readings on my return I may have to try adding a few fish to keep cycling with them in.

Okay, the tank was left for 3 days while I was at work (with the readings as above and also the water changes as in the post above)

On getting back, the No2 and No3 were at zero, but so was the ammonia, so I am still unsure what the go is with the tank. I am guessing I could say it has cycled, but having never seen high ammonia, I cannot say for sure. I guess the best bet is to get maybe 3 or 4 tetras and put them in while watching the readings and doing water changes...

Thoughts?

Did an almost complete water change today, since water was cloudy. I also cleaned the filter media in the (old) tank water and rearranged the gravel etc. Put the heater up one more degree, it's now reading about 28'c. Think this is too warm for fish but since there's none in there at the moment it should be fine.

The pH was really low this morning (6.4 before WC) so I am guessing it was because all of the organic matter caught in the rocks etc that I got out with the water change. Seems like my vacuuming technique needs some work :/ haha

Still no fish?
Cloudy (milky) water in a new tank is not a bad thing. Is the water surface clear?
You should continue to "feed" ammonia in your tank or else bacteria will die.

Since I don't have ammonia, I guess fish food is the next best thing? But I was told also that it can make the tank mini cycle to add food now... I have the JBL Denitrol, someone here mentioned that it mostly acts as food for bacteria already there, rather than adding anything...

No, no fish yet since I was sick for last 4 days and didn't get out of bed really. Working again for the next 2 days so I think I wil lget the fish after that...

Update- readings still steady at zero ammonia, nitrate, nitrite. Added a tiny (2ml) bit of Denitrol and some fish food last night, reading zero again today.

I want to add fish but the onyl issue now is although the CI is good, the pH and hardness are out of control

pH still very low at 6.4, will not budge, and the kh is reading in the red zone no matter what...

Not sure what to do, as I heard it's best to get fish to suit the water and not the other way around, but I'm not sure what if anything will tolerate this! I'm away for 6 days, day after tomorrow so don't really want to add fish today and just leave them, hoping for the best UNLESS you guys think dong a water change before I leave and another on Day 6 of fish added would be okay... but I think too risky if the fish is/are new...

anyone?

Denitrol has bacterias, it's not a "food" for bacteria. It will "feed" your tank with bacteria.
What is CI ?
