    • Fluval EVO 13.5 did it!
Breathtaking nano reef from Fluval: the 3D peninsula, all included in one nano tank. Placed on the kitchen countertop, big enough desk or stand-alone stand, an aesthetic marine tank in your home. Hardcore Hobbyist experienced or not, and whatever your taste in the nano reef, this is a beautifully designed saltwater aquarium. And functional. Now the bad things targeting the newbies: The Fluval EVO 13.5 box comes with a recommendation, what type of fish and corals to have in this aquarium. Follow that, if you don't, and get excited for more fish, expensive ones, or want that awesome coral from the fish store this tank will end up crashing, losing the livestock, and sold for pennies at the garage sale. -This saltwater fish keeping hobby requires money and knowledge. No matter if is Fish Only or Reef -Whatever livestock you put inside your tank, treated like your beloved, dog, cat, snake, iguana, or tiger you keep as a pet. Fluval EVO 13.5 comes ready to set up right out of the box. You just need extra: Knowledge( cycling the tank, water quality, and temperature control), rocks (dead or alive), sand (not a must), marine salt, thermometer, heater, saltwater test kit, salinity test, extra wavemaker for improved water movement (not a must). Reverse Osmosis is a must!!!!. You need to prep saltwater for a new set up and future water changes and to refill evaporated saltwater with fresh R/O water. No way around. Get it cheaply in jars from a local store, buy a home system (in the long run, you have insurance, cheaper solution, you get to maintain control) whatever you do, freshwater from your house will not do it. The only biggest problem all nano tanks and bigger ones too ( the smaller the tank the fastest things go wrong) have is temperature control in the summertime. If your tank is going above 80 F you have to modify the outlook of your Fluval to be ready for summertime. Give up canopy, Cooling fans (water evaporation fast), different suspended lighting, your home ambient temperature no more than 78F for cooling fan to keep it under $80F. And all of this extra hardware, chosen carefully not to end up with an ugly Fluval EVO 13.5 tank on your home!!! The expensive route to keep the stock Fluval outlook is a Mini Chiller, not many on the market and the only one with some degree of effectiveness and aesthetics is this one from Amazon https://www.amazon.com/Chill-Solutions-11415-Thermoelectric-Aquarium/dp/B00JY6UJB6/ref=sr_1_1?dchild=1&keywords=Chill+Solutions&qid=1588560696&sr=8-1. On this chiller, the maker is out of stock, the dedicated marine sites out of stock., Amazon has it for $50 more than the market and without tubing and the right pump. Yes, you need to have the right pump and the tubing to fit inside the Fluval filtration chamber in order for this chiller to work. Sorry for the bad news. ... show more

    • The Perfect Beginner Saltwater Tank
The media could not be loaded. The Fluval 13.5 gallon saltwater tank kit is the perfect setup for any beginner saltwater enthusiast. Out of the box you'll have everything you need to get started, including a powerful LED that can sustain some hardy corals and a pump that's quiet and effective. The filtration media that comes with the tank is enough to get you started, although you'll be better served to upgrade it as you start adding livestock. I'd highly recommend you purchase this tank with the following items in your shopping cart: - A 150W heater: this tank doesn't come with one, and although the heater is oversized, it will ensure a stable temperature. - A pump: saltwater tanks thrive when there's good circulation. - Live sand: you can buy a bag of live sand on Amazon. I put 20lbs in mine for a 2.5" deep sandbed. - Live rock: you'll need to pick this up at your local fish store (LFS). - A Saltwater Test kit: for monitoring parameters and ensuring your tank has cycled. By using live rock and sand, you'll be able to cycle this tank within 3-4 weeks. Once established, weekly water changes are recommended considering the tank doesn't have a refugium and it's a small body of water. I'm keeping 2 Clownfish, 1 Watchman Gobi, a bubble-tip anemone, a peppermint shrimp, some hermit crabs, emerald crabs, turbo snails, zoanthid corals and 1 pincushion toadstool coral in this tank and they're all doing really well. ... show more

    • EVO XII Unboxed
Review Image by Amazon Customer
The media could not be loaded. This review is based on the consideration that I was not adding water for several days in any case but on a dry fit of equipment. This arrived a little over 24 hours ago and I will update as a resolution comes. Packaging was solid, the actual product is boxed in a printed cardboard box and well protected, this is further encased in another cardboard box that is slightly larger and offers protection to the printed container, mostly from errant box cutters. This second box is further packaged in another larger box with foam corner protection/suspension such that there are 'shock absorbers' on all 8 points of the inner container. All in all it is packaged very well. Unboxing the inner package, with the tank itself was not difficult. The innermost, printed box contains the tank and parts, again suspended on foam blocks with additional foam protection for the glass/fragile parts, and additionally the entire assembly was in a plastic bag. All pieces were accounted for. Upon closer inspection during a dry-fit of components it was found that the tube-bib leading from the return pump had been snapped off the threaded section (picture 1). This is a minor issue corrected immediately with superglue but indicative a shipping issue - the smaller diameter bib which is shipped loose (not screwed into the pump) arrived whole as expected. The most serious issue thus far is the light bar. It started to malfunction immediately upon being plugged in. No amount of attempting to activate the controlling button would change the mode of the light. Indeed the light did not illuminate at all but only flashed as seen in the video. Even upon unplug and restart it does not return to daylight setting but only this flashing. The tank itself is wonderful. I am especially fond of the raised base. The equipment bay is not large enough for an Aquatic Life 115 skimmer despite the claims on that product's reviews however it will only take a few minor modifications to make it work. It would be most appropriate to locate the skimmer in bay 2 and that requires further mods and usually the removal of the equipment bay lid. This should not be an issue even with jumpers but I cannot be sure unless I can get this setup working successfully. Bottom line is ~28 hours after receipt this is one star. I could not put water in it as shipped because the return pump was compromised. This means cycling the tank is cycling the tank is likewise compromised or at least seriously impeded. Most important though is the lighting issue. The benefit of an AIO is the convenience of not having to supply lighting as an external component. Thus far trying to get support has only led me a link directly to the supplier's website. I was not able to register my purchase for warranty at this website and my request for assistance there is pending. I was not at all impressed with their online market space or my ability to address this issue. My dissatisfaction is extended to Amazon as a whole as they are listed as the supplier (despite Hagen being the ultimate supplier). We will see what tomorrow brings. Update: I spoke to a gentleman in customer service named Julio this afternoon. It took less than 10 minutes to get a new light bar shipped out. The longest delay was my downloading invoice. Great customer service experience. ... show more
