I want to have glosso growing in the front left,,DHG in the back left...and hill going from the middle to the right wall. and seperating the sections will me some nice white sand. And i need 2 things, some sort of divider to keep my DHG and glosso from going into my sand, and something to go in between my seachem flourite and the sand so it doesnt mix. Any suggestions for my dividers?

You could try some thin clear plastic that will bend easy. This should work for separating substrates and plants.

No matter what you do, the only way to really keep DHG out of the sand is going to be to keep cutting runners as they grow into it. It grows fairly aggressively and will jump over, go under/around any barriers from my experience. When the roots have nowhere else to go they will grow runners vertically out into the water. This will be especially important to keep it out of your glosso. If you have a good barrier it will be much easier though, as all the runners will hopefully be on top where they are easy to see/cut.

Eventually, the sand and flourite will mix a bit, this is almost impossible to stop in the long term. You can keep it relatively clean though with a bit of effort.

I had a tank were I tried to separate the two. I used a piece of posterboard like material from an arts/crafts store. I dont remember the name of the maker but it was a white plastic sheet that is used for dry erase markers. With white sand it is nearly invisible. Clear would be prefferable, but I never found anything both flexible enough and durable enough to leave in there long term.

If you go to this link:


And look at my bottom 55 gallon, you can make out the line from the plastic divider vaugely, but like I said, it is pretty well hidden.

You can get a small sheet of plexi from any hardware store. If you heat it lightly with a torch it will become very flexible. You can mold it to any shape you want. If you don't ahve a torch even a lighter held a few inches from the plastic wold work.

I have made some frag racks for my reef tank that hang over the edge of the tank with this method. So the slight curves that you wold want for your barier should be no trouble.
