i have an easy to make above the tank basking area. the only materials needed are plexi glass and an aquarium sealent. its cheap too

here is the write up on mine:
Any questions, feel free to contact me!
Materials needed
*Sheet of plexi glass $8-18
*Normal plexiglass sealant $6-7
*Plexi glass cutting knife $4-5
REMEMBER: measure twice, cut once! It will save you a lot of time, I know from experience
To begin:
1. Measure your tank width, from lip to lip. See where the duckweed is? (Pic 1) This is the lip of your tank. Measure that too, that’s where you’ll be balancing the platform.
2. Measure how long you want the platform. This is up to you, really. Personally, I made the bottom piece shorter then the two sidepieces. That way there is a little protection barrier on the sides to keep your turtle from climbing over the edge and off into space. With a scrap I also added more of a barrier by just taping it to the completed platform (pic 2)
3. Write down the measurements for 1 bottom piece, 2 sidepieces, and 1 back piece.
4. Go to home depot/lowes and ASK THE SALES PERSON TO HELP YOU. This is totally the key. They can usually cut the plexi glass for you free of charge. They will also know how to get the most out of one piece. Get your pieces cut and *keep the scraps*. While at the store pick up plexi glass sealant and a plexi glass cutter (usually right next to the plexi glass.) the cutter is for if things don’t measure out right, or you need to cut the scraps down for something. I used all of my scraps, by the way- they come in handy.
5. Ok! Now the fun part! Glue the back and 2 sides *onto* the bottom piece and let it set. This is going to take a long time and it’s going to be messy, just warning you. You’re going to have to sit there for a bit and hold each wall up until the sealant sets a little. Once all the sides are up you should have a 3-walled box. Congrats, you’re almost done!
6. For the ramp up to the platform I used my old turtle dock. You can put it in the middle, to the left, whatever. Turn it around so the long end is pointing into the water and the short end is on land. Put a HUGE glob of sealant under the dock and push down and hold till it sets. I also sealed all around the dock to make it watertight so water couldn’t get in there and rot the foam. (Notice how I didn’t actually turn the dock around, silly me. I got that idea from someone else on the forum) (pic 3)
7. If you pick it up, does it sag in the middle? Yeah, mine did. It’s no problem! Take a scrap and cut it down to a 1-2 inch width and the length of your platform. Seal it to the bottom, on the very edge near the turtle dock. This should reinforce it and keep it from sagging. (Also pic 3)
8. Congrats! You’re done with the platform. Haha, now its time to decorate. I sorta made a box of the open area on the platform with scrap plexi glass and since it was waterproof I planted grass. Torti loved it! When it got high she would bulldoze through it, flatten it over the end and slide into the water. Eventually it died, but now I have gravel and ornamental glass sandollars/rocks. It looks ok, I guess.
This dock is simple and cheap. It doesn’t look the best, but it gets the job done until you can afford/have the time to make something better. If you have any questions, lemme know!
