It is what it is, acrylic tubing. Score it where you want your cut with a razor blade and break it with even pressure. Works like a charm, and seals up great with the murlok fittings.

Used this to drop kalkwasser on coral. Worked great.

I used the tubing to acuascape small rocks. It is holding up very well. They are easily trimmed with a small saw.

Useful for all sorts of functions from holding an airstone at the bottom of a bucket or using as a probe to flip snails over that fall to the sand bed.

Originally this product did not work with my aftermarket silicone tubing that I bought off of ebay for the dosing all the solutions. The standard tubes that came with the BRS 2 part doser (202317) worked great! However, BRS does not sell that kind of tubing separately so I went to home depot and bought Everbilt 1/4 in. O.D. x 0.170 in. I.D. x 20 ft. PVC Clear Vinyl Tube from there and it was perfect. The link is:

Hope this helps for everybody who had problems. Good luck!

Don't buy for air line tubing, works great in push connect fittings

Doesn't fit into/outside of standard airline tubing - had to use some heat-shrink tube to get it to attach for my application. A little disappointed there, but I can't find this stuff anywhere else either.

Great to use for a DIY dosing container / ATO. I have also used these combined with a Mur-lok 90deg Push Connect and airline tubing to create a mini siphon for daily cleaning of a fish QT tank for fish waste and debris off a bare bottom tank without removing much water. Thank you BRS!

It seems like most people have had good luck with this, but I did not.

I tried using this with the 1/4" RO bulkhead fitting sold here at BRS, the BRS Top Off Doser (50 mL per minute) and a 5 gallon bucket (in the tank stand) controlled by a Reefkeeper controller. I installed the bulkhead in the lid with the rod inside the bucket in the hopes of being able to set a draw level that was near, but not right at the bottom of the bucket. I could not get this setup to maintain a prime and keep working. I had to change out this rod to a regular piece of 1/4" poly RO tubing and it's now working fine.

I tried two difference pieces of acrylic tubing (tried multiple cuts to make sure it was a clean/flat cut that would seal well in the bulkhead) and two different bulkheads...no luck. It may just be a limitation of the pump since the ID of the rod is significantly smaller than regular 1/4" RO tubing...perhaps the pump can't generate enough suction to draw reliably through the small diameter...or possible I just wasn't getting a good enough seal with the rod in the bulkhead...or maybe a combination of the two.

Had I know this wasn't going to work I would have just stuck to the original setup which was a regular piece of RO tubing sticking through a small hole in the bucket lid...

These work great! High quality product

This worked great as my tubing for my new OXO Dosing Containers

Good tube, used it to make dosing containers out of the old 2 part containers. Tube is what it says and works well. Like that it's acrylic so any glue made for acrylic works to glue it. Only turn off was it looks like they busted off the pieces by just snapping it in two instead of cutting it so the ends are all jagged and rough,...mainly an inconvenience to cut off an inch at the end to get to sound material and give it a decent finish. one star off for the sharded ends.
