Best lid on the market

I was hesitant to buy this lid at first because I previously had a lid from another brand that claimed to make a lid similar to this brands lid... they aren't similar at all, specifically in terms of quality. This lid is by far the best lid I have on any of my 9+ aquariums, I'll likely be slowly moving over all of them to these lids. This lids clearances are super tight which ultimately makes the top more stable on the tank, a big issue I had with my previous top was how much it slid in every direction on the tank, that is not an issue with this lid. This lid is also extremely clean, no scratches and more importantly no words or ugly logos etched into it, although the kraken logo is rather appealing and I wouldn't have minded had it been on the lid. I also was not aware that this lids mesh was replaceable which is a major plus. This lid is very thick and feels super sturdy as well, they did not cheap out on materials. The top looks absolutely stunning on my tank. Their support is also super fast at responding, and very professional. Their company being veteran owned is also a major plus for me. I wasn't aware of this before I first contacted them with questions, that played a major roll in me deciding to make the purchase.

I'd also like to mention that their coral viewing glasses are phenomenal, I took a chance and bought a pair and the difference is actually insane.

My lid was difficult as it was a custom order

My lid was difficult as it was a custom order. The Kraken team did an outstanding job of going over the measurements and getting the final product just right. Great job!

This is my 4th Lid from Kraken

This is my 4th lid from Kraken. That should say it all! Four reef tanks all 4 different lids. Each one fits perfectly. This one is so perfect because it follows the contours of the AIO and if you don’t have extra cutouts needed, it just sits beautifully flush with access to the entire back “sump” for cleaning and maintenance. I really like the 2 piece construction as well!

Love the cover

Love the cover. Clean look. Well made. Got the feeder cup, helps my floating pellets from my auto feeder sink without being swept into the overflow.

Perfect fit

The lid fits perfectly on my UNS 90 while still leaving the filter chamber exposed so I don't need to take the lid off for maintenance. This is especially important since i have a skimmer and the collection cup sits above the height of the tank. The color customizations for the feeder door also add a nice accent.

Customer Service Excellence!!!

As the title says, the team at Kraken Reef have made a customer for life out of me and it was all because of what I call “Excellence in Customer Service”. They make a damn fine product as well. I was a little disappointed when I received my lid and noticed that the cord cutout was on the wrong side, but I flipped the lid around and it was seemingly ok except that the feed cup was now directly in front of my overflow. I contacted the team at Kraken Reef to ask for a solution, and within minutes and without hesitation, I was told that a new lid would be shipped out at no cost. Less than 1 week later, I received the shipment notification that my new lid was on its way.
Thank you Kraken Reef!

Very nice quality lid for my JBJ 28g Nanocube tank. Tried making one myself but this is a much nicer option. Highly recommend

Hello Reef Lid Perfection

Very nice quality lid! It fit perfect for my Hello Reef tank! I just wish I could have customized some sort of part to fit my wave maker wire better. Otherwise very impressed!
