Water Circulation Heavily Planted Aquarium

[brads]

Hi All,

I have a Juwel Rio 240l with 2 Aquamanta external Filters, 1 is a 1000lph the other 2000lph, inlets and outlets opposite ends with pressurised co2, with drop checker lime green, within 2 hrs of co2 coming on.

I have tried the spray bars and the flow is not to good, there are a lot of dead spots. I replace the spray bars with the duckbills and flow seems to be alot more powerful, however there are still a lot of dead spots i.e the sides and the back of the aquarium.

I was thinking of introducing a 2 x Hydor Koralia 1600s or 3200s, or would these be to much of a flow?

Suggestions please.

Assistance appreciated.

Regards,

Billy

I have an 80L with a Fluval 105 external and a Koralia 1600, and have had even more on it in the past, so I don't think it would be too much at all.

Koralias give out a wider flow than powerheads or external outlets so you could probably do even more!

Hi Brads

What did you end up doing?

I've got the same tank and run the internal, external and a power head. But plan to remove the internal soon for looks and space so will be down on flow a bit

Thanks

Hi Josh,

I also removed my internal and have 2 external Aquamanta efx.

I still needed more circulation for the dead spots, so I went for 2 x 1600 hydor koralia and is just enough to cover the dead spots, so hopefully I will see a difference over the next few weeks.

I did the same thing in my 300l but obviously the larger sizes I got good results and seemed to work brilliantly
