How to increase growth

Hello,

just trying to get this correct in my head. If I am dosing with EI and assuming I am dosing correct amounts, then by increasing CO2 and light intensity (from 24w to 48w) this will suposively give me more/faster growth without any algae blooms?

Thanks
 
In theory yes 🙂 but remember that increasing all these factors will increase how quickly algae will take hold. So if it's not balanced you'll quickly have lots of unwanted green in your tank 😉


Keen to go green 🙂
 
It is an 80 L iwagumi setup with little plant biomass. Since there are no fish, if I crank up the CO2 to ridicules levels wouldn't that ensure that CO2 and nutrients are more than needed compared to the light and since CO2 or nutrients don't cause algae, is like playing it safe. Am I wrong?
 
Yellow when lights on?? That would mean far too much co2 even nefore the photo period. Fine if you hardly had much fauna but I'd have thought co2 concentration at that level at lights on indicates too much co2. Light green yes but yellow???

Do be honest I think my DC has a yellowish colour at the moment but I am getting a bit worried now since the single Otto I have in the tank doesn't seem to have a problem so either the yellow DC colour means perfect CO2 or the indication of the yellow CO2 doesn't reflect the CO2 levels in the tank or my Otto is a real surviver 🙂

The point is do I have more than enough CO2 when the DC (with 4dKh bromo blue solution renewed every week) shows a yellowish color? If yes then I can double the light intensity and in thoery increase growth rate.

I have also seen signs of Green Dust Algae...what might cause this?
 
Hi all,

Otocinclus have quite a high oxygen requirement, so it is likely that it can survive because the open nature of the tank means high flow maintains high O2 levels, and this will to some degree compensate for the high CO2 (this is due to the Bohr effect). Having said that you should re-home your Otocinclus, as being on their own stresses them, they don't feel happy in open environments, and the high CO2 levels are almost certainly causing sub-lethal damage to the fish.

Thought he had no fauna whatsoever in there. Therefore this would cause no harm. He said he wanted optimum growth. Not to keep anything alive.
 
More light will give you more GDA. I find GDA comes when I upset the balance of the tank like a huge trim or removing a large amount of plant mass. As this is the Iwagumi tank you have I would add more plants and aim to achieve a balance before doubling the light.

Couldn't agree more, consistency is definitely key.
