Bio-Basin for 4'x2' Zen Habitats Base Enclosures

Excellent product to ensure no leaking, helps to contain isopod and springtails. easy to add to enclosure.

I couldn’t figure out how to update my last review, but I did want to give Customer Service 5 stars for not giving me one iota of grief over the seam-rip in the bio basin and sending me a new one straight away! I haven’t even received it yet, but I’m over the moon with the superior customer service with Zen Habitats. I have pestered them enough with questions to know how dedicated they are to we pet owners. Thank you, Zen, for my python’s “Forever Home”!

I love the fact it fit so well inside the 4x2x4. I do wish it came up higher like with the substrate barrier for the 4x2x4 but still worked out holding in most of the substrate without it falling through the sides! Would recommend if going bio active to make sure water isn’t corroding the PVC over time.

I’m actually sorry to write this review - I have purchased everything Zen that applies to my pet ball python, and she and I have been happy with most, even those we aren’t using. After waiting weeks for the enclosure to arrive behind all my other Zen products (deluxe spacer, stand, bio basin), I discovered a seam rip in our brand new bio basin, right where water was most likely to, and did, accumulate (under water bowl and humidifier). So, within 2 weeks of setting up a sparkly spot with all the trimmings (we call it the Taj McXan - last name McIntyre, snake’s name is Xanthippe), I had to clean up wet/muddy substrate that had seeped through the tear and onto the enclosure floor. Thankfully, I had sealed the seams of the pvc enclosure with silicone before laying down the basin, substrate and decor. I wouldn’t blame you for thinking that I caused the seam rip, but I am anal retentive enough to know I didn’t; between asking questions and following directions my girl wants for nothing. This is a relatively inexpensive product, but I don’t think anyone would be happy to have it fail within 2 weeks with less than 3 inches of substrate and a filled, non- moving water bowl on top. If you have one, check those seams; if you’re considering one, also consider reinforcing it before use.

A bit annoying that it doesn't fit perfectly, even with the tape. I've had some worms escape inside of the tank between the biobasin and enclosure. But other than that, it's great!

Works great since I also want to keep the enclosure in great condition for a long a time!

Wish it was a bit taller but it does its job im So glad i ordered it!!

I am housing a Russian Tortoise in the 4x2x2 enclosure. The clear liner fits perfectly and allows me to add enough substrate so she can dig in and take a nap. Good quality liner that I used the double sided tape to secure to the walls. Highly recommend.
