Is my water oxygenated enough?

I have an aqueon quietflow 30 in a 36 gallon and the water comes out as seen in the video. is this enough oxygen for my fish? there haven't been signs of distress. I have an air stone as well but don't have it running regularly because I am worried it is too much agitation for my angels.

 

As long as your fish aren't in distress your ok. You will know when oxygen levels drop because your fish will be gasping at the top of the tank.

 

The bubbles you're watching aren't oxygen- but airbubbles so don't say much about tje oxygenation of your water Most oxygen is taken in by the watersurface and any disturbance will maken gasexchange easier. This is perfect to me. Depends also on the "users" offcourse. Normal stocking will have no issues !!

 

Hello ann...

You can check this yourself. If you change out a lot of tank water regularly, which helps maintain a healthy oxygen level, your tank just needs a filter with a gph (gallon per hour) rating of 4 times the volume of the tank in gallons. Your filter has a gph of 200, this is more than enough for a 36 gallon tank.

Actually, with HOB's you want 10x the filtration so I would say the tank is under-filtered.

OP, you could probably add another AQ30 to give you a total of 400gph. Nothing wrong with over-filtration.

 

Hello el...

You don't need high end filtration if you're following a sound water change routine. If you change half of more of the tank water weekly, the filter is simply filtering water that's already clean. The problem with mechanical filtration is, it can't remove the old water and replace it, only a person performing a large water change can do it. You can have 20 times the filter, but if you don't change most of the tank water weekly, the filter is just taking in toxic water and returning the water a bit less toxic. If you changed most of the water often enough, you could do away with mechanical filtration altogether. But, only one water keeping in 100,000 is willing to do it.

I never mentioned that overfiltration would replace water changes. Having enough filtration would prevent dead spots, provides good circulation of the water and keeps the water cleaner and clearer.

 

Hello again el...

Not trying to put words in anyone's mouth. Wouldn't do it. Just saying that one doesn't need expensive filtration if you remove and replace a lot of tank water and do it more often.

Good chatting with you.

I don't know these kind of filters, but is it 200 gph for a 36 G tank ?
That's by far more than most of my filters do I think. Am I missing something?

 

annaleigh I think another filter would be a good idea. A bubble wall would also be an option, but as el337 said, there's nothing but goodness coming from over filtration

Manufacturers tend to overestimate the gph on their filters and when the media is added, it slows down the flow further. From my understanding, this is why everyone recommends 8-10x the number of gallons for HOB's. 3-5x for canisters.

I agree with that El, but that counts for my filters as well !!
Flow doesn't seem that bad I'd say.
But you could be right.
