My second Kraken

This company is a pleasure to work with. There was a little hiccup with this one but it was resolved promptly. Received the lid 3 weeks, to the day, from the time I ordered.

Perfection!

I’ve ordered a total of four custom lids, from Kraken Reef, and the reason I keep ordering from them is because every lid is made to perfection!

Order yours now.

You won’t be disappointed.

24 Gallon Recife Lid is everything!

This lid is more than I expected it to be! Aesthetically everything looks clean. I didn’t think it would make this much of a difference. Precision cut too! It’s perfect!

Perfect fit!

As usual the lid is a perfect fit. I love that it's two pieces rather than one. Give the tank a more polished / complete look.

EXCELLENT LID - Red Sea Max 625

I’ve previously ordered from Kraken Reef, as well as other lid manufacturers, however, after this purchase, Kraken Reef will be the only company I buy lids from! SUPERIOR product and even better service! Thank you Kraken Reef!

Excellent product and easy process

I put off ordering this product for a while because I was unsure about the accuracy of the custom options and the cost. I wish I had ordered sooner. It’s extremely well made and all the cord and filter cut outs are perfect for my setup. I appreciated the communication from the company before they started and the packaging was very well done.

Fluval flex 32.5

Purchased my kraken lid last week for my 32.5 fluval flex and words can’t explain the quality, fitment and craftsmanship that goes into this product… I purchased my first custom lid from toplids and the quality and fitment does not compete with the kraken lid I got what I paid for. Seeing other customers lids in there tank from kraken made me want to take this risk Evan after spending $300 for my first lid I took the chance and I could not be more happier. I have a fluval flex 9 that I will be coming back to purchase a lid for in the next few weeks from kraken.. can’t get over the fitment and the customer service too notch for sure… thanks kraken u have a extremely satisfied customer here 5 STARS!!!!
