Positioning Of Spraybar?

[Tigermoth]

Was just wondering where a good place to possition the spraybar is. I've probably got it all wrong at the moment.

My planted tank is 48" long, spraybar is only 32" long and runs along the back about 3 inches from the substrate. Spraybar holes are possitioned to hit rear glass of tank, which I thought would stop plants being blasted and stop too much surface movement. Have got more pipe to extend spraybar if needed. So how badly have I got it wrong?

you really want the flow directed at the plants as it means they will get a better supply of CO2 if your injecting it (same for ferts)

I'll turn it round then. Cheers

Is height from substrate important?

not really i dont think, if it were me id have it at the top spraying down

Good thinking. Easier to get at for cleaning too.

I would have it at the top. Dependent on the force of water I would have it level to 1 inch below the water level pointing straight to the across to the front glass.

This will then mean the water hits the front glass and goes down to the substrate.

Is there any reason why you don't want to break the water surface? Most of us do have a decent ripple these days.

Just extended it to the full length of the tank, moved it to the top and pointed it to the front. Plants aren't being blasted around too much.

As for the water surface question. I think it was something I read ages ago about it helping with CO2 levels. So probably out dated info now.

We are tending to follow the idea these days that O is just as important as CO2 to the plants (and of course is good for fish) and upping our injection rates to compensate.

More O definately gives better water clarity for reasons I cannot explain. Someone with knowledge of science may know. lol

However in some setups i.e. if you are struggling to maintain the CO2 levels on DIY then it's not always feasible to have surface turbulence.

I'll see how the plants go, that'll give an indication if it's driving off too much CO2. Mind you, I've started using better ferts as well. It all seems like a positive step forward though.

Sometimes there was so little surface movement and a sort of film would form on the water that it would prevent the tiny CO2 bubbles escaping. I was probably misguided in thinking that's what I should be aiming for.

Just fired up the brewery again btw. A bottle will defo be heading your way this time.

That's what I would do. Has shown great affects on another members tank on another forum.
