If you have a lot of dry salt you have not been changing the water (partial!) often enough and you get the residue as the water evaporates and/or hard water. If the latter, you really need to find out the hardness of the water at the fish store and yours. You can kill a new fish pretty quick putting it into water that is a lot harder than what it is used to. You can get a water softener pillow that goes in an external filter to soften the water. You might need to soften the water in a 5 gallon bucket before doing the water change rather than adding the water to the tank then softening it.
Different fish can tolerate (or need) different levels of hardness.
Today??? Our has been running 24x7 for nearly 2 months
Thanks! I hadn't even considered that possibility. I knew abkut ammonia and pH and stuff but never considered the hardness of the water.
I've had the goldfish since like January or February and they are thriving but I'll remember for any future fish
I loved the Chocolate gouramis! So tiny and cute! The bigger ones can be bullies!
Just got another seed catalogue!![]()
I'll look them up
There'd still be lots of bacteria on every surface of the tank to re populate the filter so don't worry about it - goldfish are tough.
My husband wants big Tiger Oscars that will eat anything they can fit in their mouth. So my choice of fishes couldn't co-exist with them!![]()
Thanks, that's good to know!
And aww that stinks
Those Oscars get boring, you can't add much except feeder fish to the tank.
Sounds boring
I rinse my filter on a regular basis to make them last longer. I also rinse my biofilter as needed. As long as the whole tank isn't cleaned out at one time the bacteria will quickly recover.
My arm will itch after a water change too. I make sure to wash it right after having it in the tank. If it's making you itch than your fish are probably feeling it too, so water changes will help with all problems. It's the same as good ventilation for chickens. It's really important for a healthy place for your fish.
Thanks, thats a relief! And hmmm, good point. I did wash it, several times, but its still slightly weird. Better tho.
