Two tanks with strange sicknesses

[Frida]

if the issue you run into has any regards with infections or parasites, I would check the temperature or lower it as higher temperatures breed more virulent bacteria.

Temp is 24C so in the lower range for the species at the moment.

New test kit for NO3. A little different readings than last time: up to 25-30 in some tanks… In this tank still at 5 but I didn’t add ferts the last water changes.
Also tested PO4 which I haven’t done in a long time. It was quite high at 1.8.

Conclusion: No ferts in this tank and double the amount of water changes. Note to self: write down the date on the test bottles before throwing the box away
