Not garbage but not good for marine. They need to be cleaned at least weekly, which sounds nice at first but miss a few weeks and you have a detritus/nutrient trap.

Super unhelpful answer from that guy. A lot of people don't run canisters on reef tanks because they consider them nitrate factories. They do get dirty quickly but if you can commit to cleaning them on a regular basis they work as intended. I had one on a tank and it was very useful to use for mechanical and chemical filtration as needed. For biological filtration I would look elsewhere, if you even need more.

I have 2 I've been using the 406 since julyish and the G3 since Novemberish. Just seeing if anyone out there used one and what filtration they were using with it and how often they clean theirs
running it empty will produce the same benefit as running it packed full of surface area media, its of no benefit other than water movement and adsorbing material for altering n and p levels, which brings on dinos eventually ./

I run the fluval fx4. Love it tank can't be drilled so I use what I use.
Sps lps softies nems they can work and do work. Clean mine once a month.

same, a place to control water flow, use skimmers, place gfo etc
but one thing universal in all reefs 1 gallon to 1000+
not any are lacking surface area if you're using live rock or have cycled live rock. all to the addition of that is like having a car with 5 steering wheels when 1 does the same job. its helpful to know this in reef tank design, you don't have to pack in media its not like freshwater, that's all slicks, rounds, no jaggeds, low surface area so we pack in the filtration
marine is inherently by design already biofiltration in every single niche even on top of corals. filtration bacteria/those can can alter ammonia are found all over in tanks. fluval filters run my freshwater setups just fine, I like em. if I ran one in a reef it wouldn't harm a thing full or empty, I just happen to have more fun with bubbled reefs vs pumped ones.

@brandon429 Thats not true. What we do to remove po4 and no3 does not the canister or sump

Same all my coral look great and only clean it prob once a month too. Have you had a dinos outbreak?I run the fluval fx4. Love it tank can't be drilled so I use what I use.

Yes because I was running heavy gfo to remove phosphates and carbon dosing. That created dino. Not the canister

sfin52 are you cleaning the cartridge any special way or are you just changing it out? What are the levels of nitrates and phosphates in your tank as well, just worried about the longevity of cartridges personally
