Discus with white circle on tail and on body... help please

[Sandnukka15]

Forgot to say, replace the salt being removed during water changes

Yes of course... appreciate the advice.

This next question has nothing to do with this topic but how many frozen cubes of hikari frozen foods would you recommend for all 10 discus per feeding?..... its hard to tell when I feed them bc at this size I aim for 2 cubes per each feeding per day.... which was 3 feedings total.... I've heard of others feeding more but they are so slow at eating and picking off the bottom that I cant tell.

I was thinking

2 cubes morning
3 feedings in between with 1 cube each
2 cubes late night.

These are hikari frozen food cube sizes for refrence

5 cups for 75 gallons with daily 70% water changes daily can be pricey with api aquarium salt prices at around $6 per 65oz for me on amazon. Is there a cheaper salt solution you would recommend?

I'm not sure about feeding blood worms, I've never really fed my fish this. I feed a beef heart mixture, black worms and color bits, but i would ignore the instructions and just feed as much as they can eat within 5 minutes or so. In the few times I have fed them blood worms, whatever floats to the top stays there, never gets eaten and spoils.

"aquarium salt is a rip-off. I bought a 40# bag of Morton Pure Natural salt at home Depot for $8. Works perfectly!

It looks like it has gotten worse today and I see the same type of patch starting to form on the other side of his body

The photos may be too large. They must be <2mb.

I just noticed you don't age your water. A ph swing is not the only concern with aging. I would pick up an aging barrel or reduce the water changes to 30% x 2 or 3 times per day with several hours in between. If this is progressing you may want to pick up some Furan 2 and lower the temp to 82 if it looks bacterial or fungal , but lets wait another day with a different water change routine to see any changes. It looks like they may have come to you with a bug.

How would I go about using furan 2 if I'm doing daily water changes? Is it a med that is dosed everyday?

The original white patch looks like it's gotten deeper as if it's a sore. Middle of the patch looks to be red

Noticed one have long white poop. So guessing maybe a parasite?

Would api general cure help?... I have 3 boxes of this on hand

I would treat your tank with sera which contains iodine.
