the only ones with matching hieghts are the 28 n 41 (1/8 inch difference), but youd still have to have a different rack for hatchlings.
chances are you won't be able to get a proper thermal gradient running it along the back side of the adult tubs. imo building a rack for each style of tub will be less headaches.
melamine resists bowing very well, personally I think poor design gives it a bad rep. I mean seriously its 3/4 inch thick lol
when people build their racks and have just have 2 sides and screw the shelves into the sides, all thats holding the wood up is those screws, for example this rack i got off craigslist. all thats holding up each shelf is those screws short spans it works i guess, but its really not ideal.
I prefer to build my racks in layers, each shelf sitting on top of the sides and back of the shelf below it. then you will never have to worry about bowing. The dividers I have in it arn't even really needed, but I had the extra wood, so why not. I could have 3 people sit ontop of all that and nothing would bow.
