Aquarium Acrylic Lily Pipe Inflow Outflow for Live Plants Tube Filter 12mm

I am pleased. I used the lily tubes on my new 12-gallon long bookshelf aquarium. Filtering a 3-foot long, narrow aquarium was problematic. However, these lily tubes combined with my Zoomed Nano 30 canister filter, I was able to have the water circulation I wanted.

Fits 12mm hose. Decent finish on the cuts into the acrylic (one very small chip on one of the slots on the intake). The inside of the lily where the tube flares on the output is a bit rougher than the rest of the piece, but the cut at the end is clean.The outflow is a good bit larger than shown in the diagram. I got ~130mm down and ~145mm further out... I can lift the pipe higher if needed, but it's sticking out almost 50% more than advertised, and with the outflow at the front corner of the tank, that's significant in terms of sticking out in front of the view. There's nothing wrong with it as far as functionality, and I'm pleased with the inflow piece. But I'm displeased with the larger size outflow, because I got the smaller one with hose sizes for smaller filters like what goes on my 20 long. But it looks oversized for my tank.

It's always on my to-do list to write a review on these pipes since I'm a massive fan and I own 4-5 sets now. Perfect for the clumsy aquarist who loves the look of glass Lily pipes but tends to break them.. the price is excellent, quality is superb, and they are my go to.
