I've got same set up. Thinking about heater and Sponges in left. Sponge it came with in middle then biohome in the last compartment with the pump. The water would be cleaner by the time it gets to 3rd chamber.
That foam you first put in is a great idea. I did that before seeing this video. Those small slits clogs up fast when you over feed like I do. The foam gives the trash more surface area to cling to and lets the water flow easily around it. I have found my fry and shrimp will go back there to hide from the bigger fish and eat like kings without getting sucked into filter because the water pulls from a larger area it's not so focused over powering them.
Interesting I like what you did. I actually got a second foam and put in the first compartment with two packs of rings. Then just pulled out the carbon in the second compartment and put a pack of rings there as well. In total about 4 packs of rings. Also fully aquascaped with co2 and cycled with the usual startup bacteria. The first fish added a 5 days later. From there a few more every week. (Fish and shrimp)
Lee Pearson I actually removed the first filter now and am just running the original without carbon. I found that durning the startup of my tank when the plants where smaller it worked great. However now with my tank being filled with plants I found the bio filter was so great it would remove the nh4, no2, no3 to quickly when I added fertilizer to the tank causing a nitrogen deficiency in the plants.
I should note I added a second light to the hood doubling the wattage and CO2... so I guess if your primary focus is fish keeping double down on that filter like the video or myself. If you go high tech and aquascape it all up it might be too much filter.
Lee Pearson yep that’s what’s running in my tank at the moment 2 bags of the bio rings and the original sponge. I find carbon is great if you need to remove medical or you put to much fertilizer in. So keep the pack on hand it can be helpful for removing chemical from the water in a pinch. I found it to be a great balance. But again I am using a lot of plants which are processing a lot of the chemicals.
I just left the original sponge where it was, replaced the carbon with mature media though. I then put 3 bags of media in the first compartment and I have pump and heater in last compartment.
@@leepearson4400. Hi, it's going great. I'm a little over stocked with around 50 rcs, 4 huge amano shrimp, 6 Cardinal tetras and 3 otocinclus. However, there's enough media in the first compartment to support them and then some.

Hello I have this tank. I was wondering how you found it after that filter mod. Was there much difference? I've ordered some bio gravel and am aiming to put it in where the carbon is.
I've had the tank for almost 2 years, the flow that the standard pump puts out is really high and, unless the fish you are stocking like a strong current, it will cause issues. My dwarf shrimp and chili rasboras really struggled in the tank until I modified the output of the pump to reduce flow. I've since supplemented with a small sponge filter hooked up to an air pump, while not aesthetically ideal, the shrimp love it and I've gained additonal mechanical and bio filtration because of it.
@@michaelfox6820 Theres a plastic suction tube that goes between the top of the pump and to the output nozzle, I perforated it with a sewing needle in about 10 spots iirc. This bleeds some of the flow which results in a lower volumetric flowrate for the pump. I have since converted to a walstad tank and removed the entire hidden filter/pump.
@@AQUAGUYUK Hey man, question, gettin a bit of an issue with surface crud, I just downscaled from a 60 Jewel that had a surface skimmer, so missing it a bit, I know Fluval have their own but it looks like you have to massacre your top cover to have it in.
Hi Alan, how are you finding the fluval flex? I am wanting to get one for my bedroom to house a fighter with some shrimps and pygmy corys. How often would you recommended doing a water change? Thanks
Check your water out the tap for nitrates it can be as high as 50 ppm ,,,,,but ideal change frequency would be minimum 25% every week but more if your tap water good you may need to block the bottom filter vent if using sand for the cory and also get some plants but maybe invest in the fluval timer and set lights for 8 hours ,,,I have notice I slight hum bear that in mind if in the bedroom ,,hope this helps.
@@AQUAGUYUK I've read the hum is probably due to the impeller not sitting flush in the filter. I would take it out and push it in a little, probably 2 or 3mm, this I have been told will stop the hum. My nitrates are approx 10ppm so its pretty good.
AQUAGUY UK I’ve had my Fluval Flex 57l set up for a week now cycling. Does pushing the impeller in a little help with the humming as mentioned in the comments?

for the Flex 57, a 50w is a little on the low side. I was recommended a 100w Deltatherm) It's more than it needs so should be more efficient and able to adapt quicker/easier. IMHO
problem is it blocks very easy especially 45 pores per inch and now we have biohome products that can even promote anerobic bacteria meaning lower nitrates
I use pumice stone which is what seachem matrix is made of, cost me a 10th of the price but each to their own i use what works in my tanks to achieve balance ,sponge is a good media for bio and mechanical filtration
Overkill for a tank that size. There will only ever be enough bacteria to handle the bioload. You could have ten tons of media and it wouldn't make a scrap of difference.

Did you not find when you put foam in the grills on the left that the flow into the back was reduced I did the same with mine however the level of water in the rear compartments dropped quite a bit and I nearly burnt out a heater as soon as I removed the sponge in the grill it filled right back up again
