I did a 50% water change. I will add activated carbon tomorrow and that should clear the rest out. Thanks

Hi everyone- Was running a quarantine on some new fish. 20G cycled tank and running for months, no plants I added about half a capful. Kinda guessing the 2 teaspoon measurement. Anyway, tank is very blue. I am not sure if I added too much and what I should do. I also added Erythromycin and General Cure. Only filtration is sponge and HOB with sponge, no chemical. I read after the fact not to mix with Erythromycin but no where does it say what happens. I also they read after on the bottle it can cause an ammonia spike. Should I do a water change to dilute?

Meant to also ask about crushed coral. My water is relatively soft. I add kH because the substrate I use currently is left over from shrimp tanks and softens water so I’m always fighting that. I’ve seen guppy breeders use floss and coral in a corner filter. I am starting new tanks with pH neutral substrate. So where and how would I use crushed coral if not as a substrate?

thanks for the warm welcome. Thank you this is all very helpful and encouraging. I feel better knowing it might not be me and I will watch the feeding to eliminate that issue. I really don’t believe it was disease or parasite related. I use Cory quarantine method. They were purchased on eBay from here in the states. Oregon I believe. They could of course have been imports to begin with, but who knows. I do use aquarium salt. This brings up a question. I love panda Corys and learned recently while reading up on guppies, which as I said are new to me, that while guppies like salt Cory’s do not. Everyone seems very happy, am I overthinking this. im looking forward to learning more and expanding my tanks. Thanks again for responses.

Hello All, first post here. Looks like a great forum. I have kept aquariums for 20 years on and off. Saltwater, fresh, planted, crystal and pinto shrimp, etc. However, I am new to guppies. I bought some breeders a trio. Both females and male have died. Lots of fry from two successful births are alive and growing well in grow out tanks. The trio died at different times. Water parameters are all zero. Sometimes nitrates are 5-10 but many times zero as I have lots of plants. I believe I might be overfeeding because in every instance the fish look like they have a swim bladder issue and die hours later. The last one was the male. I fed the tank kinda heavy. Left for the gym came back and he was swimming upside down. I put him in methylene blue and he died within the hour. All others died in similar fashion. Thoughts?
