Fluval Flex Owners - Experience, Mods, Advice

[Sespe Badger]

So I 3D printed some lid lifters from Thingiverse and put some plastic "granny grating" in between them in case I get jumpers in the future. I just zip-tied them together. I had to learn to print with PETG for this, so while I was at it, I printed some tank decor. He is still so light he needs the big rock on his back, even though he is tied to several smaller rocks.

I cut a round hole in my lid, made an adapter fitting, and plopped a kessil a360 right onto my flex 15. Par is like 700 directly under it, which has given me great growth on certain corals. It's a very very simple tank. I run a mp10 for flow and dose AFR via a small dosing pump. It's been up more than four years now and it grows corals (including acros) well enough that they are growing into each other. It's extremely hard to work in such a small space for fragging. I have big clumsy hands and I am constantly breaking corals. Can't wait to get a much much bigger reef.

Anyone have any experience with UV sterilizers with this tank? Specifically the aqua shield uv sterilizer desktop? Starting to get some dinos and I want to nip it in the bud.

I ran an aqua top 5 w sterilizer in mine for quite a while. Worked well.

Hi all. I picked up a used Flex 32.5 and it came with the brackets to hold the lamp in place (attached to hood), but it lacked the very specific sized screws. Anyone have any ideas on how I can get said screws so I can confidently attach the lamp? Thanks in advance!!

I have the Tunze 3152 Osmolator as an ATO and yes the sensor is in the middle chamber. I don’t use Kalkwasser myself, I use AFR. I added a nano protein skimmer and that seems to help. I also have a HOB refugium with Chaeto as well.

I did have the second Marine 3.0, but I ultimately built a canopy to use 3 Orphek OR3 LED bars.

Do you still have the marine 3.0 lights? If so, would you be interested in selling one?

Send me a pm with your details. I test them out and make sure they are still working. The cost would be shipping only.

PM sent I think. Never done one before so if not let me know. Thank you so much!

What are thoughts on a spray bar vs RFGs in these tanks? I have 2 jebao eow-5 wave makers for flow, so not sure which would be more beneficial in conjunction

Anyone have a skimmer in one of the side chambers? My center chamber is used up with the ATO sensor and dosing tubing holder so would love one for the side chamber

I do, an Icecap Nano, very tight fit but I made it work. The other side has the intank media basket

Ah sweet! Is that this one? I have two in tank media baskets now but thinking of switching one to a skimmer

Nice thanks. Any way I could get a pic of how it looks in your setup?

When I get home I will take one

While on the subject, what are people using for dosing tubing holders? I got one off Etsy but it’s really bulky

Were you able to grab a pic?

Ah nice thanks! Looks tight but it fits. And you’re pretty happy with it? What’s the noise like? Also what dosing tube holders are you using, if any?
