The best way to ensure your water is dechlorinated correctly is after you take out the old tank water, and just prior to starting to add your new water, add a full capful (based on your directions of 1 cap per 10 gallons) to your 10 gallon tank, and then add the water.
As for the filter question, unless you only plan to lightly stock your tank, your best bet is to get a stronger filter. Generally recommended that you look for twice the filtration rate that you need. For example, you have a 10 gallon, so a 20 gallon filtration would be great. Alternatively you could add an additional 10 gallon filter to gain the additional filtration in combination.

When you do a water change and you want to treat the water with dechlorinator, you must treat the whole tank. So if the dechlorinator you have says 1 capful per 10 gallons, and your tank is 10 gallons, you should add 1 full capful as per the instructions. Regardless of how much water you take out. If the tank is 20g, and you do 50% water change, you should then add 2 capfuls, and so on.... Hope this helps and removes the stress you previously have,
Also i agree with other posters, you should remove the carbon and replace it with bio media as this is more effective. JUst make sure you clean the media in OLD tank water or dechlorinated water, but only do so when the filter really needs it. Suc as reduced water flow or blocking.
I clean my 2 canister filters maybe every 3-4 months.Fiiiiiiiiiiissssshhhhhh!

I strongly disagree with the above post. You don't treat the whole tank. If you had a 1000 gallon tank and change 100 gallons you treat 100 gallons. You don't need to dechlorinate water that is already safe! The best way for a small tank like yours is to dechlorinate in the mixing bucket before adding to the tank.

Please can you explain the reasoning behind dosing the entire tank when making partial water changes? Why?

First off, your water changes and basic approch are excellent - good work. Most advice here is excellent.
A few words - what appears to have happened is that the charcoal (what everyone seems to call carbon) was what did the fish in after you rinsed it in water that had chlorates - activated charcoal can absorb chloine componds like a sponge and then it released them right into the bio-media in the filter wiping out most the bacteria. While charcoal has a purpose, you are far better off just adding extra bio-media. By the way, the amount of bacteria in charcoal is trival compared to bio-media so the loss of the charcoal would mean little; it was the chemicals in the tap used to rinse the charcoal that caused the filter 'crash'.
As for dosing the tank for 10 gals when you just replace 5 gals is just a safety measure - neutralizer chemicals are cheap but getting the dose slightly wrong can kill/harm fish and/or the filter. While it would be fine to dose, say for 5 gal's worth of neutralizer when doing a 25% water change, most people just can't measure these small amounts easily. That all said, if you really did do such a worthless water change like a 1 gal change, guessing about half a capful would be fine. Not just a good idea if the w/c is close to 5 gal and you just guess for the amount by judging what half a cap full is. As for the chemical, the filter bacteria 'eat it' so no, it does not build up and is harmless.
Best of luck and keep up the water changes until the ammonia drops to near zero; be on your guard for a nitrite spike.

A 75 gal with eight Discus, fake plants, and a lot of wood also with sand substrate. Clean up crew is down to just two Sterba's Corys. Filters: continuous new water flow; canister w/UV, in-tank algae scrubber!! Finally, junked the nitrate removal unit from hell.

As for dosing enough for the entire tank, in general I agree with you, there is no real need to dose the entire tank if you are using buckets and can add just enough for each bucketful added. I can see instances where it might be necessary, such as using a python or aqueon water changer, since water is being added directly to the tank, chloramines will also be added to the entire tank. Another time might be if there is a larger than "normal" amount of ammonia or nitrites in the water either during cycling or such as in my case, often having 1ppm ammonia in my tap water, as per the instructions on the bottle of Prime (I don't know what the the other brands instruct in this case) it is safe and recommended to add enough to dose the whole tank.When I go fishing I just throw sharp rocks in the water and wait for the dead fish to float to the top...

Everything happens for a reason. Sometimes that reason is you are stupid and make bad decisions.
I think my fish is adjusting well to the four gallon, He's laying on his side attempting to go to sleep on the bottom of the gravel.

I've done some more reading on this - I think the key is whether you add the dechlor directly to the tank or to the water in a bucket. If to the tank - dose the entire tank size. If to the bucket before pouring into the tank - dose the bucket size only.
Well, I've learned something.
I'd stick to dechlorinating water before it's added to the tank for small tanks (bucket water changes) though. It's less wasteful.

I think the whole point of adding the dechlor directly to the tank is to make dosing easier. For a bottle of prime, for example, the right dose for a ten gallon is to fill the cap to the first thread inside the cap. Unless you go out and buy a dropper with measurements on it and exactly measure each dose, you're more likely to overdose the tank by guessing how much to add to each gallon.
This is just going off of my own bottle of prime. I'm sure there's a drops per gallon reference for other dechlors.
The other benefit to adding it right into the tank is to avoid a fatal mistake. We all get distracted during water changes sometimes. I personally watch tv while i'm doing a wc. Adding five individually treated gallons of water to your tank gives you five separate opportunities to forget to add dechlor.~Manna

Good info here. After these posts and doing a bit more reading, I just ordered a new filter and also a bottle of Prime. (was using some other product before)
This is the filter and Prime I ordered:
First, is this a good filter for my setup/situation? And second, assuming this filter will fit in my space, what is the best way to begin using the new filter without causing yet another crash? Should I take the bio foam piece out of my old filter and put in temporarily somewhere in the new filter so I save the bacteria?
Once this whole situation is behind me and my tank stabilizes, I will be back here reading for stocking suggestions. I did feel that the tank was too crowded with 9 fish. Also the danios were way too active for this small tank. I think 6-7 fish is a good amount - but would like to find fish that are a bit more interesting to watch. The platys were kind of nice. I also did enjoy the betta. Can I keep a betta and 4 more small fish with this 20 gallon rated filter?
