Well, nothing fits very well. I got the kit with lid props, vent covers and feed hole cover. The vent covers fit the best, but they slide around in the slots. The feed hole cover does cover the hole, but don’t jostle the lid if you have it opened with the lid props. At least one prop will fall in the tank and the feed hole cover will slide out of the hole and down behind the tank. \n I also got the “low flow” spray bar. It has a split (I’d guess this is to allow the rigid material to slip over the ball for mounting) which squirts water every time it is removed or reinstalled for cleaning. It isn’t exactly low flow. I had to pack some filter floss into the bulkhead connection (not the spray bar -didn’t want to open that split any further) to get it so my fish weren’t ... MoreWell, nothing fits very well.

Ok. This guy works wonders! His tech engineer mind can produce just about anything! When used properly as each "prop" is labeled for what corner, front and back, L + R.\nI was so pleased 2 if my family members have ordered too. If you want quality, not at the cost for his labor alone, get these. If you want to upgrade your LED's like I did, this gives you the extra 2 inches you will need, on a rimless tank for that application. Don't drop that lid, prop that lid!

Found this mod kit on a YouTube channel almost on accident and decided to give it a try. Well, more like my eyes popped out of my head at how much I needed all of this for my setup. Got here today and I had it all in and used within three minutes in a full tank even. The grills are fantastic and made me feel better about my betta being up near them eventually, the food enclosure lid gives me less fear of said betta trying to escape (like they do), and the lid kickstands? Revolutionary. Made it so easy to fully address a floater plant issue I’ve been having but too frustrated to address with one hand propping the lif and the other trying to wrangle about a million giant duckweed. If I get another fluval, you can bet I’ll be getting another kit. Already eyeing other ... MoreFound this mod kit on a YouTube channel almost on accident and decided to give it a try.

3 stars for solid craftsmanship, cool concept and modern shape.. but the swim space for fish is SMALL and a good portion of the tank is taken up with filter. The floor of it is 11"x11" = 122 square inches. I tried for 2 years to make this work. My fish swim circles and don't school.If you decide to buy any way, the pump can rattle pack filter material around it.. problem solved. The light sensor gets effected by moisture.. I solved this with a piece of milk jug cut and wedged to cover the sensor.FYI. My new 20 gallon floor is 12"x23.75" = 285 inches, which is more than double the side to side swim space of the 15g flex and within minutes my fish were actually schooling.
This is a great looking tank. The curved front is a nice modern design and the white cover and trim so much nicer than the usual black or plain glass look.Really love the lights and being able to change colours or just have the white light, all have +/- buttons to increase or decrease brightness.The reason for four stars not five is it is quite tricky to clean given the back compartment being divided into three smaller sections. The pump is also great, would recommend a second in the spare compartment at the back to help with keeping the tank clean. Love how these are all hidden, giving a really stylish modern look.
The Flex 15 is probably my favorite tank of the 6 I own. I always end up dismantling the all in one kits, but not this one! This tank offers a ton of room for additional filter media (I added additional sponge and bio rings), and the light is great for growing lower light live plants-pretty much 80% of the widely available plants in the market. I did add an after market submersible light to mine and a timer/dimmer for the included lighting system. I gave this a four rating because the pump cannot be adjusted and the flow rate is really too strong for large-finned fish like bettas. I currently only house dwarf emerald danios and Amano shrimp, but I still needed to slow the flow. In addition to the extra sponge in the filter compartment, I added sponges to the outflow ... MoreThe Flex 15 is probably my favorite tank of the 6 I own.

In addition to the extra sponge in the filter compartment, I added sponges to the outflow and it did the trick. It’s an easy fix, but Fluval really missed an opportunity to provide an adjustable flow pump.I completely recommend this tank. It was packed securely and delivered quickly. I really want the 34 gallon now!
I love this tank. My first non-square tank and it really looks nice.The fish seem to enjoy it as well. I have one female Betta and five Cory Cats in mine. They're "Violet Femme and KD's Catfish Band". I used Fluval Stratum as my substrate and added some betta bulbs as well as a couple of fern cuttings. I started the tank with old water from another tank cleanings. After one week tank with 1/4 water changes every two days using distilled water tank was safe & stable. I'm really happy with this tank and looking into going for a larger one.
First of all, I know there were reviews out there that claimed that their tank arrived cracked. Mine, however, arrived in a very strong box that was packed inside another very strong box-- All intact with nary a scratch. The unit comes complete with a filter and very cool lighting. I would have given this five stars, however, the remote for the lighting was not working because the battery was dead. Opening the latch to access the battery was difficult beyond imagination and even the guy on the YouTube video on how to change the battery on the Fluval lighting remote had a problem opening the latch to access the battery. Once I was finally able to open the goofy latch, remove the battery, and head out to the store for a replacement battery and got the remote working, ... MoreFirst of all, I know there were reviews out there that claimed that their tank arrived cracked.

Would I purchase this aquarium again? Absolutely. It's a good 15 gal tank for the money.
This tank is the perfect size for my planted, freshwater, fish and shrimp aquarium. It sits on my table next to the television and I enjoy watching my fish swim back and forth while watching tv. It was a quick and easy set up and I changed the filtration just a bit to speed up the cycling. I added more bio rings in the pull out compartment, removed the charcoal packet, added more foam to the left of the pull out compartment and poured a bottle of seed (fish tank cycle fluid) over the foam sponges. I also added some stability and clarity (to help with clearing contaminants and to aid in cycling) as well as a purigen packet (to help with tannins in the driftwood). All of these allowed my tank to cycle completely in 3 days. After testing, my parameters were perfect, ... MoreThis tank is the perfect size for my planted, freshwater, fish and shrimp aquarium.

All of these allowed my tank to cycle completely in 3 days. After testing, my parameters were perfect, the fish, plants, shrimp and snails transitioned the new tank and now, weeks later, everything is healthy and the plants are growing. The light isn't the greatest and the control, unless pointing directly at the little bump on the top, won't work. I have all low light plants however purposely but anything requiring medium or high light will not grow well in this tank. I have about 2 inches of substrate (for plants and snails) in the tank and that too cycled completely in the three days. Very happy with this tank and look forward to enjoying it for years to come.
I bought this Fluval flex 9 about 2 months ago and it looks nice and is a good size. However unlike the Fluval betta tank it first does not come with a heater, and the filter does not have an adjustable flow rate. I bought this tank for a betta and I had to constantly have the filter unplugged because the flow was far too strong and the betta couldn't swim. More than once my betta stuck to the intake grate. This tank would be great for fish that like a higher flow rate but if you have a fish that is not a fast swimmer or has large flowing fins I would not recommend. You can adjust the direction of the water coming out of the filter, but only so much. Being able to adjust the filter strength like on other Fluval products would have made all the difference.

This is really the first Fluval product that I've ever bought that I was disappointed in. Only getting 3 stars because there are some varieties of fish that may do well in this environment. For bettas I would give it 1 star
