I have a problem that for past month i cant get a grip on it

I set up 210 gal tank for my big fishes for past few months i lost control on the watter
Its greenish brown smelly and i cant get a grip on it watter changes wont help at all i am loosing it i have other tanks i use same RO watter no problem i can put new born fry in that RO watter nothing happen no loss there
is this tank still a tank cycling? if it was why so smelly stinks
its a first time i have that expirience when i started the tank i kept it for a month no fish and then checked all so i dont kill the fish i placed a fish in there and all was fine then a month later i loose that watter quality

There are only 12 fish in there not bigger then 12in long and 3 Plecos 12in+

Can you guys give me some ideas watter changes wont help

Filtration 1 FX filter temp set to 77F all levels are noramal proiblem is witht the clearnes of the watter and the smell it kills me!

Thank you!

ps. I will get some pictures soon so maybe you can see

Sounds like you just need more filtration, plain and simple. That is a big tank and it will need a lot of filtration and also a lot of water movement to filter properly and prevent the water from going stagnant. Besides the 1 filter, do you have any powerheads moving water around?

air is moving the watter from the bottom on the back wall

i though that might be filtration but that FX is rated for 400 gal and i know the over rate those filters ( they would probably work with one fish.. he he )
just wanted to get some feedback from other people cause i get different opinions

maybe you should consider a uv filter...sounds to me like you are a prime candidate.

How much water changes are you doing and how often? 3 plecos 12"+ and 12 other big fish (I am assuming bigger fish although less than 12") is a lot of bio load. You may have to do more and bigger water changes.

I would agree, that's a lot of big fish even for a 210. To test this out, stop feeding for 2-3 days while undertaking some major water changes. See if that improves things.

Running the FX5 is fine, but if it's getting clogged up and slowing down, it's going to be less effective. You should probably plan on opening it up to clean it once per week.

The water movement suggestions are good ones too. I'd use a couple of powerheads rather than just air.

As far as 'Is the tank cycling'? Only testing will tell. You said all levels are normal. What tests have you run and how did you cycle the tank initially?
