Spraybars are among the best answers but they are not always used because they are ugly and are very difficult to implement correctly on a large scale.Just my opinion..........
Why bother with the spraybars? This goes against everything I normally think but with a tank that big I'm not so sure a spraybar is your best answer and maybe simply relying on some well placed powerheads could work better.
Reef tanks have little in common with planted tanks in this regard. Freshwater leaves require a certain flow rate and direction across the surface of the leaves in order for the boundary layer thickness to be reduced sufficiently to maximize the movement of the gasses across the boundary layer.I guess you could argue that doing away with a spraybar is just wasting flow but if you are to look at a reef aquarium then returns from a sump tend to just be an angled nozzle under the waterline and distribution of flow is primarily down to powerheads.
More so I also think a spraybar is more useful when used to create flow in a tank and just think that 1700 is a bit far for it to work and create a cycle.
Water that falls and crashes onto water or onto other surfaces immediately evaporates the CO2. For this reason, it is better to avoid falling water and instead to have a full siphon from the tank and to extend the tube in the sump so that the end of the siphon tube is just below the surface of the water. Crashing over baffles and other obstructions should also be minimized to reduce off-gassing of the CO2.Any reason for this given the water will get oxygenated as it falls into the sump?
As Edvert mentions, our 10X rule was meant to neutralize the effect of manufactures who provide inflated flow ratings.Does anyone know whether the 10 times rule scales up like this? Does the ratio change with very large tanks?
I completely agree with you Clive and haven't looked back since you advised me to give them a go, I just think the size and flow rate needed for an aquarium this size would be quite something.Spraybars are among the best answer
Agree 100% - but this is just my opinion.Well worth at look at for your monster tank IMO. Then like Foxfish suggests you can have a low flow going though your filter so less CO2 loss and the Gyres can take care of the flow/turnover.
This might give you the flow you want, but I would build a huge CO2 reactor anyways to get enough CO2 dissolved, and this will need a large pump anyway, and distributing that through a large tank will be easiest with a spray bar, you might add the Gyre, or even need it to get the distribution correct.f a product like the Maxspect Gyre exists and gives you full control then why not utilise it?
They 'suck' as well as 'blow', you can adjust angle, power, direction, height.
I believe Filip has a couple of big CO2 reactors to go with his two return pumps that will dissolve the amount of CO2 he was talking about before.I would build a huge CO2 reactor anyways
Agreed.distributed evenly

Good luck and have fun😀😀
Priceless, Pics for the family albumfirst thing that will go in after I half fill it with warm water, is my kids
Oh and if everything looks OK, put some large flow disrupting items in the tank ( mimicing the layout you have in mind) and see how that works out
I've some food grade glitter I could put in, to see the flow around obstacles. Too much mess? Food colouring enough? (got that too!)
Thinking about it the doctor medic o2 creators are quite good in this situation, just get the el cheapo one from hinterfield. Doesn't need to be on the whole time but the mist it creates is very buoyant and hangs in the column for some time, they are actually quite good at seeing how your water is flowing around the tank and with the benefit of some pure o2.
I brought some of these to try instead of the Maxspect before I got a spraybar in my planted tank and they really are awful, very noisy and just feel cheap.Have you seen these from Jebao
