The white spots may be something called Ick, which can be contagious. Look into treating the Ick or you might kill all your fish. That was a LOT to load your tank up with all at once!!!!

Water hardness refers to the mineral content of the water- so things like iron, magnesium, etc.  Any “salt” with chloride is soluble, except for silver, lead, and mercury.  So if there was a bunch of magnesium chloride in the water, it separates into magnseium and chloride.  SO you could have high chloride content, but it depends on the water source.  Generally chlorine is added to water for purification.

If you add new water to the tank, make sure you leave it to sit- usually overnight, if not a full 24 hours.  This’ll help dechlorinate the water- the chlorine is a gas and will eventually rise to the top and escape.  It takes time.  Heating the water helps, but obviously make sure the water isn’t too hot for your fish.

Generally, adding any fish to a tank increases the ammonia levels- the fish poop and pee and basically create an ammonia mess.  Make sure you’re not overfeeding them- that can cause the levels to rise.  You can try changing out the water- new water should have very low ammonia.  That said, it’s only a fast fix and doesn’t fix the root of the problem.  It might be a time thing.  It takes time for a filter to become fully helpful, and for the fish to settle down.

If your area uses chloramine, letting it sit won’t remove it.  Chloramine removal requires a conditioner.  I’m not sure if what you’re using helps with that- you’d have to ask the pet store people.  I would still let it sit overnight to remove chlorine that might be trapped.  I would also avoidmore than about a 25% water change at a given time.

Actually… If you’re using AmmoLock, I believe that works for removing the chlorine part of chloramine (don’t take my word, I just think that’s how it works), but not the ammonia part.  It “locks” it- it’s still there, but it won’t affect your fish.  So your ammonia levels might be tested as high, but your fish are probably ok.

First off, what size tank is it?

I think you just added too many fish too soon so your tank is cycling again. I personally would stop using any chemicals except for a chlorine/chloramine remover. Make sure the water is well aerated, and keep the feedings minimal. Continue changing out some of the water every day if the levels are getting too high, but don’t wash any of the filter, glass or gravel.

You do not need to let the water sit out. I have multiple tanks and fill them directly from the sink with a python hose. If you are using a bucket or similar, use your dechlorinator before adding that fresh water back to the tank. Do NOT use bottled water.

I have never heard of having to add the plants and fish at the same time. Many people keep planted tanks with no fish at all, although in that case you would still need to “feed” the plants. What kind of plants did you get?

To me it just sounds like you added too many fish. Try rehoming a few of the fish or leave out the chemicals and just do daily water changes until everything evens out. Make sure you clean out the filters once in a while — I just had a problem in my tank where the filter had gotten clogged (Still functioning properly so I didn’t notice) and was dumping ammonia from decaying food back into the water. I was baffled as to why my ammonia kept spiking until I cleaned the filter carbon & sponge and all this yuck came out.

That is a lot of fish at once for a ~10 gallon tank. What kind of pleco is it? Most get way too big for that size of a tank, and the corys should be in a group of at least 3.
