how much of this is enough for a 20 gallon high fish tank?

You would need other substrate in addition to this as it is not a Stand alone substrate. Use about 1/4 of this bag and the rest as a custom mix. Completely depends on your scaping though, as well as the root base demands of your plants. Look up a few aqu scaping forums for more details

It really depends on how deep of a substrate bed you want. That said, one bag should be fine. I used less than 2 bags in my 20 gallon long.

I have only this substrate in my 29 gallon and it is sufficient to grow plants. I recommend periodically supplementing with Flourish in order to maximize plant growth, but a decent group of fish will provide enough nutrients for decent plant growth.

I believe the whole 3.48oz bottle is made to start up tanks 20 gallons and under. You have to use the whole bottle.

The 200ml would be more than enough. Which is great, because you will definitely want to have some extra once you see how great this stuff is!

Depends on the total water volume of the tank. 5g or less, 1 would be sufficient. But you should really have atleast 1.5g per betta.

Yes, the rule of thumb with fish is 1" ( as an adult) per gallon. They need to have room to grow or they will be stunted and not be as healthy. I always google how big a certain kind of fish would grow into then decide if it will be good. If you haven't gotten this yet you may want to reconsider. It goes through 2 different kinds disposable filter every week to two weeks costing about $8 each time combined unless you buy in bulk, but that still gets pricey as well.

Sorry, I'm using a regular 20lb tank and I have yet to run out. I've had it for quite a while.

I have a 20 gallon aquarium also and I have a 100 watt but you could probably get away with a 50 watt. I always set the heaters up vertical so really couldn't tell you on that

I am using 150w for a 40 gal tank (but it has only about 20 gal water in it).

I don't know if that is answerable. Would depend on ambient temp and other factors. My guess is 1 or 2 feet max though. The aquarium heater I have in a 40 gallon tank is only 40 watts and it cycles on and off and can raise the temp 20 degrees above ambient I think without being on all the time. So for just 2.5 gallons I wouldn't think you would need very much @ 20 watts per foot.

Depends on what you have in the tank and the length. 4 foot wide fish only two 24" light pack will do. If you have coral you would probly want 4 24" minimum. High lighting coral need 3-4 watts per gallon. Most coral 2-3 watts per gallon will do.

I'm pretty sure it's perfect for you 20 gallons , I use one for a 30 gallons tall on a DIY trikle 10 gallons filter.

No, this is for a 20 gallon high tank. I believe their is another model for the 20 gallon long tank.

that all depends on what filter you have, for me i have a turtle and a 60gallon tank, so i use about 100grams on a fluval405 , and it lasts about two months with clear odorless water. your situation might be different , i think this should be more than enough if only for regular fish.

Clearly not enough. No room for plants or any way to get oxygen in. Basically torture for fish -- like not enough air or space.Why bother to waste money- soon you will have dead fish.

Yes it is good enough for a 200 gal, but if the pond is over loaded with fish you will have to add bio rings to keep the water clear. The bio rings also keeps the box form floating.
