The aquarium is beautiful but the water flow is too harsh. My poor fish get beat up.

I love the design of this tank, plus my fish seem to love it too. I have live plants growing happily under the built-in light. I especially appreciate the fact that the pump, carbon filters, etc. are hidden in the back, out of sight. The filtration works well and the tank is well constructed. It’s not a big tank, so be sure not to overstock with fish. I have three Cherry barbs, two Siamese algae eaters and two electric blue balloon rams (male and female). I probably could add one or two more small fish, but the current inhabitants seem happy as is. Highly recommend!

This is my 3rd Fluval Flex. I have had a black Fluval Flex 15 and a black 32.5 for years. I found two of my community fish were getting picked on by the others and so decided to move them to their own tank. So this white one and its matching stand were purchased.The tank arrived completely undamaged although not the greatest packaging for shipping. I put this tank on the newly assembled stand made for it and it looks great! I am currently using the filter foam it comes with and have a 2nd one installed in the empty chamber. Eventually, Ill be installing filter baskets in the two chambers instead of the original foam. I like to use lots of filter media and angel hair so the baskets work better as filters.The pump fits into an end chamber and provides a good deal of current that can be directed by two spigots. Since this tank isn't real big, youll be unlikely to not find a way to aim the outputs to your best spotsSeveral people here and on other net stores will also sell you 3D printed spraybars to spread out the flow even more and get more water surface movement without making strong streams. While spraybars can be harder to clean, they usually are better for calmer lower current waters for fish that are small or those who arent good at swimming in stronger currents. You can also use plants or rocks to slow down the current streams too.The huge sponge included is great for filtering most debri. On the larger foam opening, youll usually want some sort of biological rings or porus material. The smaller opening in the foam is great for a thin carbon pack and or a Purigen pack. You get some Fluval media with the tank but you'll want to buy more. The sponge and biological media will eventually become saturated with beneficial bacteria. So, only rinse these foams out in water yaken from the tank during water changes or in water treated with antichlor. Never use your tap water to rinse them or the chlorine in the tap water will kill the beneficial bacteria. Your carbon packs can be replaced and your Purigen replaced or recharged. Youll know your filter foam os beginning to clog when the end chamber with the pump has a mich lower water level than the filters. Plan on cleaning rhe foam about every 2 weeks or more often if your tank is dirty. If you add chemicals to your tank water, get used to doing so in the end chamber where the pump is. If you use a bacteria starter chemical, pour it directly on top of the sponge and let it go through the sponge. This will speed up the bacteria colonization needed for a cycled tank.In the same end chamber your pump sits in, you may also add other accessories like heaters or remote thermometers. Some people like to put in air stone here to increase the oxygen levels without being seen in the tank.There is also a honeycomb patterned screen around the top and rear sides of the tank. This helps hide the waterline at the top of the tank and mineral deposits. It can be removed carefully with a razor blade if you hate it. But it really does improve and hide the appearance of some things you generally dont want to see, especially as the tank ages and deposits become more a part of the glass.You also will probably want to have or buy a couple of prop sticks for propping the lid open. Youll need to remove the lid entirely to service the filter foam There is a punch panel in the back top you can punch out for more air and visibility or to add a small in tank accessory . Once you remove it though, its gone for good. Theres also a small feeding hole in the lid top front.Because the lid is fully seated, its great for keeping jumpers in the tank. It also slows tank evaporation into your room as it will condensate on the cover underneath instead of evaporate. On the back of the lid, its got a raised area to let your air hoses or electrical cords to exitWith this kit you will still need to buy foods and gravel and decorations, and any optional baskets to replace the filter foam, and chemical water treatments and accessories like nets and maintenance devices. But you will be able to get started with the tank and have a couple of starter fish in it within a few days.You will also likely notice that the bow front can distort the view of the inside, depending on the angle you are viewing it. Generally it will look to have a slight magnifying effect. But youll get used to that. The sides are squared off and look like a normal tank. If you have the tank placed where you can view it from behind, youll be able to see whether the filter is becoming clogged or not.My first Fluval Flex 15 black, purchased several years ago, did not come with inlet covers so I had to buy 3D printed ones elsewhere. Youll only need to install these if you have small fish that could swim between the grates. My Fluval Flex 15 white i just purchased here already had two of them installed. If you want to raise tiny fry, youll need to stuff these covers with foams to keep the tiny fry out of your filter And be aware that bigger tougher fish can learn to pry off these covers. Ive got magicians of Kuhli Loaches that can pry them off far enough to get into the filters and live there. I can tell you getting a squigly little Kuhli Loach out of your Fluval Flex filter is almost impossible. If you have fish that dig or pry on things, you may want to glue the intake covers on.This tank is rimless. So dont put stress on the glass where the seams are. Be sure the tank is setting on a table or stand with no part of it off the stand. Use the rubbery mat surface that comes with the tank to be sure its supported at all places. Because its rimless, too much stress placed on one area of the glass could separate its seams in time or with vibration.Also some here have commented the pump vibrates loudly. It shouldnt if you install it right. Dont remove the suction cups it sits on. That keeps it from vibrating on the glass bottom. And stick it down with the suction cups so none of the pump itself rests against the glass. And when installing the pump, you may have to realign or turn the oitput tube so it goes straight up to the mount. Dont bend or twist this hose inside the chamber. Do it before you sink it to the bottom and youll have no vibration on the plastic parts.OK now enjoy your tank! Your fish will likely love their new home.

So beautiful. Love the lights. My fish are loving it too. Like that the filter doesn't have to be filled with water each time I turn it back on after a water change. REALLY EASY to use.

Only just got this tank this week and have spent the evening setting it up so it can cycle for a week before the fish move across. I purchased a heater and air pump separately and have had no problems installing and hiding all of the cables, tubes etc in this tank. Loved the idea of the rear compartment for the equipment and it hasn’t disappointed. No light on yet as I’m short of sockets whilst my other tank is still active but very satisfied. Super quick delivery too!

Not sure why everyone always goes for the black tanks (myself included). The white one was on sale for $138 which I thought was an excellent price.The shipping said 1-2 months but it delivered in less than two weeks (10 days). Was packaged really well.The tank has been set up for about two weeks (used some cycled water to hurry up the process). It looks great so far I absolutely love it. Definitely a big statement for my living room as well. This is my first tank over 10 gal and the bigger the better! :)Only con, the light sensor is the little black square on the lid... inconvenient. But for the price I’m really happy.

We bought this to replace a smaller tank, arrived quickly and set it up over a week. Planted it first and left it to stand for the week. Then added four tetra from old tank. They were delighted with the space. A few days later added 8more small fish to include 3 bottom feeders.It looks really good now and have replaced one third water once. Have not cleaned filter.The fish seem happy, and not lost any.I am happy with the purchase.

My only complaint is the tank is growing algae at a fast rate so cleaning it will be constant! I’m not sure why because the water does stay clear it’s just on the glass & back wall & shows up a lot on the white back wall .. I do love the vibe of the style & I think it’s a good tank for only a couple of fish! I’m going to have to get a larger tank for the fish I got when I got this ... they are all thriving well in this tank & the light features are pretty awesome . I plan to get a Betta fish after I upgrade my size for my Goldfish that are growing at a super fast rate , my bad I should have just put 2 in there then it would have been plenty of room ! The filter is very quiet it honestly makes no noise! Very cool fish tank !!!

Good quality tank. The tank it was replacing used to leak condensation around the edge. I don't know if this is a common problem, but the way the lid fits on this tank ensures all water collecting at the top drips back inside.There is a large sealed off section at the back divided into three sections. This allows for a lot of filtration options beyond the media that it comes with.The pump is quite powerful, which is fine for the river fish I have, but some videos on YouTube suggest the need to change it for other types of fish.The built in light can be very bright and as I dont have live plants currently I've succeeded in growing a lot of algae, but this can be dimmed and also set to various colours.Note, it doesn't come with a heater, but has a space to fit one easily, hidden at the back with the filtration.
