So looking to get a rack system and i know i seen one that allows me to have different size tubs on different levels. All i can find now is the V-6, but looking to do something with steel not PVC. So im sure this is on here some where but unable to locate it.
I’m pretty sure you would want to look into Freedom Breeder.
I know I was debating on a hybrid myself when I settled on an ARS for my 70s instead.
Edit: ARS won’t have the mix and match. Just double checked after posting. Lol.
Freedom Breeder does have the build options on the pro line series.
