This video might be four years old, but it was very helpful. I hadn't thought of not using the charcoal for a planted aquarium, nor engaging the suction cups, nor putting the heater in the pump compartment. Thanks for sharing those ideas.

As much as these companies are charging for sand and gravel you'd really think they would have the decency to pre-rinse it before packaging

I just got Flex 15 for my wife. We love it. The look, filtration, and options for bio and additional form for polishing. So hooked we are getting a Flex 32.5 next.

I'm probably a bit late, but scaping and planting is easiest when the water level is only at or slightly above the substrate.

I am waiting for 9 gallon fluval delivery and ran across this very humble video! I love the compact compartments for easy set up & sleek look.

Hi Carl, bet your a fun little visitor🐾🐾

Great review, thank you for providing it. That Carl looks like he's a bit of a character.

I have 2 Fluval Flexes now. I purchased a 15 gallon a few weeks ago, it’s not set up yet as my new betta is still in quarantine. Yesterday, I realized I have baby fish in another tank, and as I was moving a 5 gallon tank to set it up for them, I dropped and broke it. I purchased a 9 gallon Flex and decided to set it on my nightstand. After setting it up, I realized it was SILENT!!! I love this thing. Excited to get the 15 gallon set up, but I still need to paint the room it’s going into. That’s going to the top of my to do list. :)

THANK YOU so much for this video!! I'm very much a beginner (Also watched your beginner videos lol) and am thinking about getting this tank and planting. Trying to do all the research before diving in. :D

polyester fiber would have cleaned it more effectively the first compartment has plenty of room for it I've used in all my tanks and it keeps things crystal clear and gets rid or cloudiness almost over night with out much effort.

Just set my flex 15 up with stratum substrate and had the same issue even after rinsing alot. Couple hours in I added a bunch of filter floss into first overflow area and it cleared up by morning. Loving the tank so far.

[pecktec]

No worries I've mud clouded more than a few tanks the same way. :)

[KGcichlids]

Smart on running the two hoses to clear it up! I'll make sure to rinse that stuff if I decide to get it lol thanks for showing us brother!

Cool new tank. I have a fluval spec v. It uses the same filter system. You mentioned you don't want to use the cart on since it is a planted tank. Why is that?

[patrickparent]

Hi John ! First off I love your videos, I learned a lot from them since I'm new to the hobby. I have a fluval flex 15 gallon as well and I was wondering what is the heater you are using with it ? I can't find it in the video description. Thanks in advance !

[lifeactionaquatics]

i have used floramax. i have never washed it. never had my water cloud up like that. just put a dish in the tank to disperse the water as i added it. tank got a little cloudy, but not like that. great video John. cant wait to see the finish of the tank, and the fish you choose to place in there.

[nickschmitz]

EVERYONE has done this before and if they say they haven't they are LYING

[GeneralGP]

I know this is a old video, but wanted to know your thoughts on using this setup for saltwater. I've seen a few videos of ppl using with with saltwater, but nothing on if anything needed to be changed out to make it work . If not can you refer a nano tank I should look into that will work great. Thanks for your time

[philthyphil]

that is how I always rinse my substrate, in tank with water in and water out. nice video John, so far I'm liking the fluval flex.

[filiplaskovski]

Any idea on how to add filter floss on this tank bro ??? I’m in need of polishing my water in my flex

[PincheMigs]

you could have put a plastic bag over the substrate and then poured the water on the bag...
