In front of my tanks
I do weekly wc like any normal person. But it's like clock work it starts on the 4th day my red devil gets what looks like fungus. His fins won't open but he will still eat. All my other fish get sluggish and act wierd. Water params are fine. Ph is at 7. Ammonia is a little elevated but nothing to be worried about nitrites and nitrates are 0. The only thing I can think of is a large piece of driftwood I got from a local pond at the end of the summer. I washed it and took all the precautions but maybe it has something to do with it. Seems like it slowly started after I put it in. Here's a pic of my red devil as u can see on his eye and along his fins the white spots. The wierd thing is once I do a water change they instantly go away

I check my params at least once a week There always fine I'm running two ehiem 2250 that's filled with pot scrubbies the tank is a 180. Unless there's not enough biological bacteria and my ammonia spikes. That would make sense
 
Although some people can get away with a water change once per week, (some if they have highly buffered tap water, and are experienced once per month) . But a water change regime should not be set in stone. Water changes should be fluid, and a reaction to condition, be they tests or a fishes obvious health.
To me, if after observation your fish shows signs of distress after 4 days, that means a once per week water change is insufficient
If your pH is 7.8 right after a water change, and drops 7 two days later, it may mean you need to do water changes every two days.
The buffering capacity may also be very important. If your tanks alkalinity drops within two days, that also tells you you need more water changes.
The fact that you have a trace ammonia, but no nitrate suggests your tank is not cycled, and the only thing keeping your fish healthy is diluting the ammonia in your tanks water with a water change.
 
Your tank hasnt cycled properly or stabilised, I'd add more filtration, more water changes
That's odd all the pot scrubbies came from a 90 I've had set up for years so that should of seeded it. Maybe I'll change them out for something with more surface area to bring up the bio

No problems in any of my other tanks at all. Just this one. Makes sense tho
