new tank, filter killing fish?

Alright so about 5 days ago I set up my first 10g tank since I was 5 years old, I used an old tank,gravel,filter,heater,and temp meters. I ran hot water over the gravel and evaped the remaining water off.cleaned everything else as good as a meer mortal could with meer mortal hands.I filled the tank and placed the gravel in along with the heater,and filter(changed the pads out). i let the filter run for about 2 days, allowed the water to reach proper temps and added in a dechlorinator not sure of the brand. I added 6 zebra danios on the 2nd days and they did well, woke up the next morning and the third smallest one was stuck to the filter dead. Next morning after that the 2nd smallest one was dead.Now im not an expert but i figured that if it were an impurity in the water the smallest (little peckerhead) would be the first to go due to the fact that ussualy smaller animals are affected quicker. So i thought maybe the filter was suckng the fish to it at night so for a quick fix i used some zip ties to make a little barrier around the inlet and 2 nights have passed with no deaths.

I apologize for the wall of text but im at work and trying to get this posted before heading home for the day.

Also this is a great community and theres lots to be learned thank you for all the guides and such

Welcome to the forum John! Have you tested your water parameters? You say you just set this tank up so I suspect the tank hasn't cycled properly. Ammonia/nitrite levels may be such that it weakened your fish allowing them to not be able to swim strongly enough to escape the "pull" of the filter. Healthy fish are able to avoid being "sucked" up. Are you able to post your water parameters?

I'd bet Aunt Kymmie is right. Fish died from ammonia poisioning in all likelihood. When you set up a new tank, you have to establish the nitrification cycle (we call it cycling) before fish go in; sometimes they manage to survive (but may still be damaged internally), usually not. One of us will offer more help when we have your water parameters (ammonia and nitrite).

I could only second what was said above, get yourself a test kit, get the parameters posted and get help.
In case you do test water and your ammonia and nitrite is too high, however you already have fish in there, do an instant big water excahnge for them guys, that could help them to survive.

Agree, and dose the tank with "Stability" which is a biological bacteria supplement made by Seachem and available in most fish stores. it instantly adds the necessary bacteria. Of course, the fish may be too far gone at this point, but if one is still alive its worth the chance to save it.

From what you say she wasn't injured, that is fortunate.

Get numbers from the store when they test, not just "high' or "OK" stuff; that means nothing as you're trusting their judgement which may or may not be accurate. With the numbers you know the actual condition of the water and if there are issues we can advise accordingly.

Also, if ammonia or nitrite is above "0" pick up a small bottle of a biological supplement like Seachem's "Stability", Hagen's "Cycle", API's "Stress Zyme" or similar. It adds the essential bacteria (or in the case of Cycle works the same way) that will immediately take care of the ammonia and nitrite from one fish (I'm hoping it is still alive).

i had the numbers from the store but while at the mall i lost them. the amonia was i believe 2x the toxic level,ph was fine, and one of the nitrates was high too. i did a water change a few minutes ago and added in nutrafin cycle and will get the water tested again in about 3 days. I also will only be feeding the fish once a day until the system is more stable. what do you think?

If your nitrate was too high then i'd highly recommend a large exchange of the water.
Also to not feed your fish for few days is ok, they will survive that (For example, mine are ONLY fed every other day and then I don't overfeed but small amounts).
And yes defiantly get the water rechecked. Or easier on you: Buy a test kit, that way you can do it at home ANY time something seems odd.

I did roughly a 60 percent water change, pet store is walkable and its free so im going to hold off on getting the test kit for another week or so. thanks for the help guys
