So my toilet was blocked and I think I cleared it by using drain clean from the hardware store, but down when I flush the water rises to the top of the bowl but goes down fairly quickly but when I put the smallest amount of toilet paper it won't flush it almost like there's not enough pressure and the water still rises to the top. Been like this for a week don't know what else to do

You have partial blockage. Clear water can get past it but when you put solids or paper down the drain theu get caught by the blockage and prevents the water from passing. Try using a toilet auger. If that doesn't work, you will have to pull the toilet and snake the line.
Do it now or it will get blocked completely. No kind of chemical will clear the line.

As Hkstroud said, a closet auger tool (see image) is the only way to go...costs about $30.00 at home depot! Acid or any other chemical is not only dangerous to you, but will NOT clear a blockage in a toilet (or drain line in the long run).

I have a different take on this. As for that lazy potty. Look down at the bottom of the bowl. If there is a small hole, then that is a jet that starts the syphon action. If it's clogged the water will just swirl around and slowly go down leaving solids behind. Take your finger,(UGH!!) and run it around the inside of the opening. Over the years minerals build up and cut down on the syphon (flush) action. If it is rough or you feel build up, take a table knife and put a bend in it to get around the curve in the bowl and chip and scrap it clear. Next take a coathanger and clear out the holes around the rim. They start the swirling action. And last, check the water level in the tank. It should be 1/2" below the top of the over flow tube. Let me know, Tom
