  • High-performance filtration medium sera crystal clear Professional

Nearly every aquarist or pond enthusiast has encountered the issue: murky water is not only unattractive but can also affect the water quality. Therefore, it's crucial to restore the original clarity as quickly as possible. To address this, sera has introduced a new high-performance filtration medium designed to effectively tackle cloudiness: sera crystal clear Professional.

Thanks to its innovative, patented 3D fiber design, the filter balls rapidly eliminate particles larger than 10 µm (such as suspended algae or sludge).

sera crystal clear Professional is compatible with all types of filters in both freshwater and saltwater aquariums, as well as ponds. Unlike conventional filter wool, these new filter balls maintain their shape and can be rinsed and reused multiple times.

After rinsing, they are immediately 80% reusable, making them eco-friendly and cost-effective. When paired with sera siporax Professional, the biological filtration medium offered by sera, it enhances the efficiency of any standard filter.

The product is offered in two sizes:

Optimal filtration performance can be achieved by using it in conjunction with a UV-C lamp and/or coagulants like sera phosvec•clear.

Great shirt, good quality.
Color: Light Blue Melange, Size: Large
This brand is solid, really good quality material and a great look and price. Maelreg continues to impress me, I've now purchased 6-8 of their shirts/hoodies and 2 pair of joggers. I really like them all.

I’m Team Maelreg!
Color: Dark Grey Heather, Size: 3X-Large
I’m a huge fan of Maelreg! I’ve purchased numerous polos, a hoodie, a pair of shirts, and some golf pants, as well as two of these quarter zips (and I currently have a third one in my Christmas list). I love the way they fit and the way they look. I’m a bigger guy too, so it’s not easy to find fashionable “ath-leisure” apparel that doesn’t make me look like a popped can of Pilsbury biscuit dough. The only thing close to a complaint I can think of is that these are a lightweight weight material and the collar doesn’t want to stand up on its own. I wish Maelreg made a medium weight version with a little sturdier of a collar, but that’s just me.

Nice fit!
Color: Saxony Blue Melange, Size: X-Large
Great fit. Very comfy. Not too heavy. (Think late spring, early fall weather.) Material and stitching seems high quality. Slightly stretchy fabric. We’ll see how it holds up to wear and washing, but so far so good. I’ve already purchased another in a different color.

Fits true to size and good quality
Color: Black Grey Heather, Size: Large
I gave this 5 stars because I was pleasantly surprised by the fit and quality. The zipper is nice, it zips firm, it's not flimsy like a cheap zipper. For reference I am 5'7", athletic build, and 198 pounds. I ordered a size large and it fits perfect. I will buy more for sure.
