Can someone please ID this algae and explain the reasons for it growing? lack of nutrients, co2, over feeding, etc.

Hi,
Looks like BGA to me. Several reasons but poor NO3 is always a factor as well as poor filter maintenance and poor flow.

Cheers,

ok

Thanks for the reply.

Well I dont think its my flow, i have 2 Koralia 1's and an ehiem filter in a 240ltr tank, so im roughly turning over 3,600ltrs and hour, Its not my filter maintenace because i regulaly check my filter and change my filter wool.

So it must be the NO3, when you say "poor NO3" do u mean to much or to little?

Does TPN+ contain NO3?

Thanks
Darren.

Yep, when talking about plant nutrition "poor" always means not enough. TPN+ does contain NO3 as well as other nitrogen compounds but you may not be dosing enough of it. :)

OK, you're welcome mate. If you're new to it all then it's best to check the tutorial section of the forum for some pretty good tips. There are articles there about CO2, plant maintenance as well as dosing and light.

Cheers,
