My new awesome Koi pond - thanks Nick!!

Nick Johal has serviced my koi pond for several years and has done a great job each time. A couple months ago, in late June, I was experiencing some slow leaks in my 25-year-old pond and needed quick repairs as my daughter was getting married in my back yard in early July. Nick offered me several options and I decided to completely remove the existing pond & materials and replace it with a deeper, wider pond, approximately 2,000 gallons. Since I had only a couple weeks before the wedding, Nick brought a team of guys to complete the work - he started on a Friday and completed it on Sunday! He and his team did a terrific job in replacing my entire pond in only 3 days. See the attached pictures of my new awesome pond! Nick has even come back, on his own, twice, to ensure I knew how to clean all the filters and keep the pond safe for my 19 koi fish and 7 red and yellow eared sliders (turtles). Thanks Nick and your team for your dedication to making my pond one of a kind - we love it and enjoy it daily!

Beautiful! Awesome! Relaxing! Enjoyable! Maintenance Free! --Our backyard is now an oasis. These are just a few of the words that come to mind when I look at the pond A1 built for us. Nick helped me build a small pond a couple years ago, which was really nice so I thought. Nick advised me at the time to go bigger, stronger and with higher level maintenance free filtration. He warned me I'll want to in the future and boy was he right. The new pond Nick and his team built us is very carefree and easy to maintain. It stays clean/clear and is breathtaking to look at. It is AWESOME and pictures don't do it justice, but I posted some anyway. Thank you so much for our little spot of heaven. It is something we will enjoy for years! P.S. I very much appreciate your attentive support even after the pond was built. You have great customer service. Thank you so much!

Marking new bottom drain locations

Nick helped us repair our underlying pond plumbing issues by replacing all the pipes with schedule 40 pvc , laying a new floor, installing aerated bottom drains, resealing our cement pond , reconnecting our skimmers , and installing new pumps and aerators. In addition he also reconnected the bottom drain lines to our existing vortex filters, converted a chamber to a moving bed, and helped acquire and install 2 bakki showers. We hope that our updates to the 8000 gallon pond will last for many years to come and be supported in case any issues arise

My floor got all messed up as well when they were working

Customer service is really important in any industry and I really appreciate that the owner, Nick, comes out to personally handle any concerns we as consumers have. The team came out to do a concrete pad for me in my backyard and was able to do a very nice job. I know there are many Companies that do concrete, but I was referred by my contractor and friend to use them because of their good craftsmanship. I totally agreed with that part. On top of the work itself, something really worth noting is their way of rendering situations. I originally had a concern with the Company and immediately, Nick came out personally to talk to me and render the situation. I call that real professionalism and taking ownership. Most companies just do one gig and leave without caring how their customers feel, but not Koi, they make sure they do what ever they can do rectify any problems you have. Again, I'm happy with the results and the work their team did and will be recommending my friends to work with them in the near future. Will be posting up pictures of the work, but it's a bit too late so I can't take good pictures.

The Koi are doing great, loving their new pond

See all

The moment you walk in, you…read morecan tell the tanks are well cared for and the livestock is healthy, vibrant, and properly maintained. That alone already sets them apart from a lot of other places. What really makes the difference is the level of knowledge and the way they approach helping customers. Instead of just trying to make a quick sale, they actually take the time to understand your setup and what you're trying to achieve. The advice feels genuine and experience-based, which is huge in a hobby where the wrong guidance can cost you time and money. Their selection of corals and fish is solid, and everything consistently looks like it's been handled with care. On top of that, their prices are very competitive--honestly better than most other places I've come across--which makes it even easier to keep coming back. It's clear they take pride in what they do, and that shows in both the quality of the store and the overall experience. Whether you're new to reefing or have an established tank, this is a place you can rely on for both livestock and guidance. Definitely a strong option if you're looking for a dependable and knowledgeable shop.

Aqua Lab Aquaria - After cleaning

Update 3/12/2026: I…read morerecently bought a house in San Jose that came with a pond. Unfortunately the previous owner had passed away and left no instructions, so I had absolutely no idea where to start. I've never had a pond before and knew nothing about how to maintain one. I remember having a great experience with Aqua lab back in 2016 so I called them back up and Kent was incredibly helpful from the start. He took the time to walk me through everything and explain how the system works without ever making me feel dumb for asking very basic questions. We decided to do a one-time deep cleaning to restore the pond. Before the scheduled cleaning, Kent stopped by to check out the system and figure out what actually needed to be done. He ended up fixing a broken part, doing a full deep clean of the pond and the filter/skimmer, and adding beneficial water additives. Since I live about 3 hours away, he kept me updated throughout the process with photos and messages, which I really appreciated. He even left me some pond tools to use and offered to come back another time, at no extra charge, when I'm at the house so he can walk me through the system in person and show me how to do the regular monthly maintenance myself (or help with that if I decide I'd rather have him handle it). His pricing was very fair and actually came in lower than other local shops I contacted. Overall just a really great experience. I've attached before and after photos of the pond. Highly recommend Aqua Lab and working with Kent. What a great guy!

High tech Aquarium was quite of challenge for me and aqua lab aquaria guided me to finally built my ideal setup. I no longer have room in my aquarium for plants but this is my favorite store for planted stuff. Another bonus is that they are only store to sell co2.

The store is always beautiful, clean, and full of unique and hard-to-find fish. You can really tell how much care and passion goes into everything they do. The staff is incredibly friendly, knowledgeable, and always willing to answer our (many!) questions and help guide us in the right direction. It makes such a difference, especially when you're new into the hobby! Lastly, as a mom, I have to add one of my favorite touches: every time we come in, they give my son fish stickers, and he looks forward to it just as much as seeing the fish. It's those little things that make this place extra special. Highly recommend stopping by if you're into aquariums--you won't be disappointed

Long story short, what I wanted to get would eat my shrimp and they made sure I understood that. Could have easily sold me those fish.

I had to call at 3:30 PM just to check, and they said he was "almost ready." I didn't pick him up until 4pm. When I got there, there was NO haircut done, just a blow dry. You couldn't even see his eyes. I had clearly asked for a teddy bear cut, but they claimed they thought I didn't want a haircut, which I never said. I didn't realize I had to say "haircut" since I'm already paying for the service. I left and came back at 7 PM after they said they would fix it. There was a slight trim around his face and ears, but still no proper haircut and the sanitary trim (which is included in the $70 package) was not done. I was told manager Joe would call me and never got a call from him. I had to call a couple days later. I asked for a partial refund since the haircut wasn't completed and the assistant manager let me know that the manager refused, even when I offered to just pay for the bath and blowout. Paid for a full grooming and didn't receive it. Poor communication, long wait, incomplete service, and no accountability. Would not return.
