[Kevino]

Please advise what happen to my plant and how to cure them? Is it a form of algae attack?

Can have a more close up picture? looks like it is an alage on the leaves. Is it black spotted?

[Kevino]

Close up picture.

GS...add PO4 if you did not and crank the CO2 a tad bit.

Sorry, what do you mean by 'crank the CO2 a tad bit'? And as for PO4, where do I get it?

[jtean]

'crank the CO2 a tad bit' means increased the bubble count. these algea are tough to get rid. pump it up. careful, if your fishy starts to daze around, better lower the bubble count

Do you dose fertilisers of any type in the first place?

[Kevino]

Yes, I do.
1) Easy-Life (ProFito)
2) MgSO4 *7H2O
3) K2SO4

The above fertilizer is soon finishing and the following are the new fertilizer that I'll be using and it is from NA.

1) LUSH Gro-AQUA
2) LUSH Gro-MICROS

What do you think?

As for CO2, I've just increased from 3bps to 5bps.
KH - 4
PH - 6.6-6.8
CO2 - 19ppm

[Phillipians]

your CO2 is too low, try to get it to 30 - 40 ppm. LGA and LGA is quite good, probably you can also add in kh2po4,and kno3 if your plants require them

[Kevino]

So as to say, I've to adjust my PH between 6.5 to 6.6 by increasing my CO2 to 6 to 7 bps?

[|squee|]

Er, in a manner of speaking, yes.

However, the pH isn't directly related to your CO2 input. pH as well as kH can be affected by numerous other substances in your tank, so do not rely on it too much. Aim for 35ppm, so that this takes into account reading errors and such.

And how come your bubble count is so high? 6 per second is like blasting. Look into improving your CO2 dissolution device.

[Kevino]

Oh knowing CO2 will increase PH therefore thought of increasing it to 6 to 7 bps. Btw, my is an external reactor from NA. Thanks for you info. Will look into the desired PH level.
