Not with the ich stuck on goldfish, Nick.
If you just return them, then the original owner is to blame for several outbreaks in other tanks if ever the goldfish are placed in other tanks.
Plecs and a dozen goldfish will never fit in the 30 gallons. You have to add 4x the size of that tank.
Apart from that, both are heavy pooing machines. They produce a lot of wastes meaning your ammonia is likely to be at a dangerous level if your tank hasn't cycled. This alone spells several water changes at that.

The bottle says cures in 2 days, but I did read that it's best to treat for 14 days. So far, almost a week and getting worse! Eeeks.
Starcollector, for this, I'd rather treat your fish with salt combined with high temps. Pls see to it that your fish can tolerate high temps. With goldfish, you are advised not to increase the temp.
I'd just continue treating them with salt until all the parasites are destroyed. Meds will do as long as they don't harm the biological filtration.
On the side note, I wouldn't try to believe everything the bottle says. It will not cure in 2 days. That will depend.
Pls do not use activated carbon when you are treating the fish with meds. This will render the meds ineffective.
Use carbon only when you try to remove the meds.
