Review: Great custom tank... - 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 spots Several 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 exit With 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.

In other words, when the timer turns the power off/on does the light come on and remember the previous setting?** A: Yes. I have mine set up on my Alexa and on the timer. **Q: Is this tank safe for shrimp?** A: yes, but I would slip fine netting over the plastic grates where water flows out of the tank to filter, to prevent shrimp from getting pulled out. It's really a nice tank. **Q: What is the best heater for this tank?** A: This is my personal favorite. I like being able to see the exact temp.

What type of plants would be ok as is it? Is it low, medium or high light?** A: There’s actually several light setting on this fluvual allowing you to go from bright light, to a variance of medium lights to low light. There is also a night setting with a blue light, a thunderstorm setting and a rainbow of lights including red, orange, yellow, green, blue and purple; that you can set at high, medium or low light. There is also a light cycled for the rainbow of lights that will fade from one to another. I use this tank as a aquascaping tank with a few fish. My plants with the right water conditions continue to thrive and grow. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great custom tank... *by D***Y on September 21, 2024* This is my 3rd Fluval Flex.

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.
