Why are 2 week old angels dying?

I am hoping someone can help me figure out what is wrong with our baby angelfish. We have recently moved and are now using well water. We had a batch turn out just fine a year ago with city water. We had about 30 babies and had no apparent problems. This batch had about 40 swimmers and now they are dying about 2-4 a day and I am not sure why. Could it be the water? We do water changes daily, but only about 25%. We clean the tank daily and feed them 3 times a day. We weaned them off the brine shrimp. Although, the fish were dying when we were feeding them brine shrimp. We keep the tank at 82 degrees. We do have lots of hard white particles that we have to scrape off the heater and the tank sides. Right now we have only 8 babies left. They are starting to look like angels with the fins popping out. What should we be doing?

HELP!!!

I don't know too much about that but did you try that stuff that takes the chlorine out of the water? also instead of using tap water look into RO water which mean reverse osmosis i have no clue what it is but it might help

Thanks. I have not used the chlorine remover. We just bought an RO system, but we still need to put it together. So what you are saying is that there is nothing I can do for the fish until I get the RO system set up? IT's too bad, they look so cute right now.

Have you checked the pH and other water parameters, and do you know the well water is OK? Maybe you should try some reverse osmosis or distilled water for every other partial water change. That would reduce mineral content while leaving enough to keep the aquarium healthy. If the well water is the only difference, it could be the cause, although high mortality rates are not unusual in angelfish fry. Here are a few more questions that could lead to an answer. Do the adult angelfish appear to be healthy? Did you move the eggs, or did you move the free swimmers? Is the fry tank small enough to have significant swings in water parameters? What kind of filter is in the fry tank? Please let me know if any of that helps.

We have a 10 gallon tank for the fry. We moved the eggs from the parents after the second day. The parents seem fine. I think you are right and our levels may be too high. The well water has been checked and it is within parameters, but in Illinois the well water is much harder than other states. I think you are right. I just moved them into the parents tank in a plastic baby fry container. I hope that helps. I have checked this water and know it is within angelfish parameters.
Thanks.

You need to be really careful about moving sensitive angelfish fry. They can't tolerate much change. On the other hand, healthy angelfish will spawn every week or two.

Moving the fry is not the greatest idea.

In my experience... I move the eggs... And whatever they're attached to... In my case a piece of slate. Before they hatch. Making sure that an airstone gives enough air movement over the eggs.

Now that being said... I've got a huge batch that are in the parent tank right now, just because the parents had been on strike and not laid any eggs in months.

I've got to get them out now. My method is to use a syphon hose... Just a regular plastic tube. I'll syphon them out of the tank, into a white plastic bucket. Then I'll syphon out the extra water down the sink. Then I'll drip acclimate them into the new tank over a couple of hours. Then dump the entire bucket full into the new tank, slowly...

Moving fry is a pain, and I try my best to avoid it.
