I had a really disappointing experience at Aqua Forest Aquatics…read more The tanks are undeniably beautiful and very clean--but that doesn't excuse the attitude of the manager (the guy with glasses). I tried to compliment the store when I came in and was completely brushed off. I figured maybe he was having a bad day, so I let it go. When I later asked a few questions about CO equipment, his attitude became dismissive, annoyed, and condescending. It genuinely felt like I was inconveniencing him by asking questions. What makes this worse is that I had already researched several items and was prepared to spend well over $1,000. Instead, I walked out immediately because of how I was spoken to. This may be a great place to look at tanks, but the customer experience was one of the worst I've had at any aquatics store. Knowledgeable staff is important--but basic respect matters more. I won't be returning, and I'd recommend others avoid this place unless they're okay with being talked down to.

The Rose Garden at Golden Gate Park is an inspiration to have some roses planted somewhere in or outside the house. Then going to the California Academy of Sciences Aquarium you wish you could have some fish as a pet and not for sushi. There are few places in San Francisco where inside of the store feels like you entered a garden and aquarium.In the crowded streets of Clement between Cafe Bunn Mi and the Bitter End bar there is a place which feels like you stepped inside nature in the great outdoors and also by the water. This place is the place to create your own flower conservatory and your aquarium at home and it's called the 6th Avenue Aquarium. On a Spring stroll on Clement street walking past the soon to be opened Rose Pizzeria and past the recently gluten free pasta restaurant Clementia I landed at 6th Avenue Aquarium between 6th and 7th Avenue. Inside it feels like a place you can create your garden, sanctuary and spa. You will see plants outside and inside. You will also see lots of flowers of all kinds. The aquarium has lots of tanks with fish inside. You will also see cherry shrimps and crabs. You also will see amphibians like the ones you see all over in SF. This a good place to start that garden and aquarium. Go on a Spring stroll on Clement street to the 6th Ave Aquarium inside is a pleasant "surprise "see fish of all types and "size" in the tank you will see the fish float their tails and see the fishes "eyes" and they sell the fishes as pets along with fish "supplies" Without nature I "can't " live without having more than one "plant" because it gives life a positive vibe which does "enchant" like a painting with tulips by "Rembrandt"

STOP, DON'T waste time looking for other aquarium services. You found the BEST one, I promise…read more Since this review will be long, thought I would emphasize on the point of my review from the beginning... instead of making you read through everything. Many businesses will help you buy a new tank... but have you ever tried to get rid of one? Not just any old fish tank but a giant one, where you could probably teach your kid to swim in it... We are talking about 400-gallon fish tank that was built way too DIY, extremely heavy, filled with livestock, ton of sand and rocks. If you are not into fish, this is easily 4,000 lbs... with many surprise attacks from the DIY "Offense Team". You really want someone who knows what they are doing... unless you want a mini flood of saltwater in your living room.. I contacted MANY businesses including junk removal but wasn't satisfied due to poor communications, lack of planning/professionalism. Thankfully, I read about Ocean Treasures Servicing on social media and did my research/stalking via FB, IG, and... reef forums and found only great things. The owner himself, Daniel, came down all the way from SF for a in person consultation then emailed me a meticulous thought-out plan on step by step of removing the giant tank. The Game Day - Daniel came with 3 team members + 1 cargo van + 1 U-Haul (this thing was huge..) Everyone from the team treated the house like their own, laid out floor protectant all over, swept every bit of sand before attempting to move any heavy items (a little sand that gets dragged can make quiet an impression on your floor), safely caught all the living creatures (all alive :D), and finished the job as if they literally CTRL+X the whole thing out of the house. Ocean Treasures Servicing is simply AMAZING. You would think after all the trouble of getting rid of a tank, I would be done... but NOPE! Since I found the best team I can trust, I am in the process of building a replacement one that is professional made by Daniel and his team...... No more DIY, unleveled, loud sounds, and random cuts from DIY stuff.... Don't Do it yourself, it's not worth it.. Trust Daniel and Ocean Treasures Servicing and just enjoy the hobby.

I contacted Cesar for a "custom" set up including base stand, basking condo, and filtration system…read morefor a 5-year-old red eared slider turtle. I could have saved a lot of money (and time after the results) if I had purchased everything myself with tips from turtle forum sites and YouTube DIY videos, but I was willing to pay for a "professional" to have peace of mind and support a local small business. While Cesar was nice and knowledgeable about general tanks and filtration systems, the outcome of what we received shows that he is not an expert on what turtles fully need- he's more a filtration and fish expert as shown mostly on his website and Yelp photos. The setup we received was not adequate and required extra money (over 2k) to fix cosmetically and functionally for us to have good access from the basking condo to the tank. Let's start with the pricing issue. I had called Cesar to get some ballpark figures which he had provided with a guess. But when the final quote came ... it was around 1k higher than the ballpark pricing (a big difference!). Knowing the new higher prices, I still contracted him to help me since I wanted an expertly set up and permanent home for our 5-year-old red eared slider. Cesar presented himself as a knowledgeable trustworthy professional. The base stand was the first to arrive (about a month after deposit was paid). Please note that we never told Cesar to do a rush job as we were more focused on moving into a new home at that time. The base stand was about 40% of the total cost. He provided photos of the stand prior to delivery, and I approved it by looks only. When the stand arrived, it did look like the picture, but it seemed very basically put together despite Cesar's claim that the manufacturer said it was polycoated to help with waterproofing. I knew it wasn't stained since I didn't want to change the color. At that time, we had a contractor on site at our new home for remodeling who looked at the stand and confirmed that this was an incomplete unfinished product, with the front portion being anything of quality and purely cosmetic. Upon arrival, the stand had doors that did not open properly. The magnetic closures for the doors were cheap and crooked. The top and back was just plywood. The back and inside had many splinters and open drill holes. The overall wood was not smooth to touch and did not seem it was coated enough to be considered waterproof. Please see provided photos and note that the photo Cesar posted himself on Yelp on Sep 24, 2021, is NOT an accurate depiction of the quality he provided us. The blue stand pictured in his photos was AFTER our contractor spent 3 whole days having to sand down the door and paint it blue. Had I known the door would have been that big of an issue, I should have let the manufacturer fix it prior. But overall quality of the stand would probably have remained the same. The door would have been just rotated to match the grain, which would have caused less work for our contractor, so that part was my fault. During our initial complaint (before we put our own contractor to work), Cesar said his manufacturer was willing to fix it but at that point we didn't trust them to do so since there were many issues we had complaints about. To add fuel to our fire, Cesar initially claimed that he did not use his regular guy for the job (why did we get a 2nd tiered manufacturer when we paid the same rates as others) and later said this guy also does stands for him all the time. Then why did ours come so incomplete compared to what he shows online? After our initial complaint, Cesar did help us discount us a few hundred dollars but ultimately it wasn't enough to justify the amount of money spent after our contractor worked for days to make it right. However, we tried to be a good sport and continued to entrust Cesar to complete the rest of the contracted turtle filtration system and basking condo set up. When the condo arrived and filtration was set up, we were so excited to be able to transfer our red eared slider into his new larger home. The condo itself is good quality in materials but was not a custom structure. At first, we did not notice any issue with the condo but contacted Cesar after a few days. The ramp length was a bit short, and our heavier, older red eared slider turtle had a lot of trouble pulling his weight up to get on top to bask. This will only get worse as time passes and he grows larger, and turtles should bask comfortable daily for their shell health. The other issue was that we could not get our arms into the tank to move anything around which presents a HUGE ISSUE FOR SAFETY. It is also not easily able to be lifted off during emergencies. If you research custom turtle basking condos in forums, you will find that the ones that sit on top of the tank are mostly 50% in length so that you can still place your arm inside the tank to clean/move things around or perhaps save your turtle if stuck. Or the ones that have a full 100%

I was worried about hygiene but Phil wore a mask, set out a tarp, had cleaned out his buckets well, and wears booties over his shoes upon request. He cleaned our tank thoroughly. He protected the fish while they were out of the tank. He unplugged and re-plugged everything, cleaned off the ornaments, squeezed out the sponge, fixed the air pump. He also graciously answered a million questions and recommended products that were as or more effective that happened to cost us less as well. If you just need lessons on running your tanks, I'd call him for training. Friendly and professional. Highly recommend. He was referred to us by Tony from PureAqua so clearly professionals recommend him as well.

Although some tissue cultured were on the pricier side. The selection of plants and livestock were OK, I would probably only visit if you need equipment though.
