Hi.

On behave of a friend of mine I have this question.
He has a 130 gallon tank and no pressure or bio CO2. Instead he use earycarbo to the maximum dosing.
But he keep getting all kind of alg.

So my question is ho much light can you have on a tank when you only use easycarbo as a carbon source.

He will buying a pressure CO2 system but not right away.

Greetings Dirk

Hi Dirk,

I'm doing maintenance on a tank of a 83 year old uncle. He has a Rio 180 with T5 and reflectors and uses easycarbo daily. He has 0,5 watts per litre and no algae. But again this is a very bad comparison. I also have 0,5 Watts per litre but my PAR value is twice as high as his if I use my reflectors. I measured 50 micromol on his tank and 100 on mine, both with 0,5 Watts per litre.

Keep in mind that "all kinds of algae" doesn't necessarily have to do with light, since there are more factors that induce algae, like missing nutrients and presence of NH4.

If you give some info about tank size and the amount of light he's actually using, it's easier to make an estimate based on PAR results.

regards,
dutchy

I go and see him this week so I will take a good look.

He mailt me this values:
NO3 = 30
PO4 = 5
15 ml profito every day so that is enough.

I did ask him about the reflectors in a mail this morning.

I guess it all has to do with the PAR.
So actually my question is how much PAR can a tank take with easycarbo.

Now we know it is al least 50.
