I switched to custom micro mix a month ago based on another thread (link at the below). First three weeks no problem and some improvements on the plants. This week I missed a the water change and my co2 was kinda low. I'm using diy baking soda citric acid mix co2 and it was low for a couple of days.

So I get this cloudy water in the last week. Water changes and purigen does not seem to solve the problem. l don't know if it is bacteria bloom or Fe-Po4 precipitate. Any help will be great for me.

Micro ppms - 3x per week;

Iron: 0,2
Manganese: 0,06
Zinc : 0,07
H3BO3: 0,05
Sodium Molybdate: 0,0015
Copper Sulfate : 0,0024

Macro ppms - 3x per week;

No3: 8.33
Po4: 1.8
K: (only from above two): 6

Mg: 15 ppm
Ca: I don't know. Only from top water

I really can not tell if it is green bacteria bloom or precipitation. So I can go with UV or blackout. Any help would be appreciated.

What kind of Fe? Gluconate can do that, highly unlikely with edta or dtpa

My guess is that it is a bacterial bloom. As least that is what it what it looks like to me.

And no water change and no CO2 likely part of the problem (unhappy plants, excess detritus). Also look for any fish that may be missing, as ammonia can also bring it on.

I'd clean filters, vacuum substrate, trim dying leaves, etc. Just get things uber clean. UV light should also help, and then some patience while tank gets back in balance.

Of course, could be completely wrong and it is micros, but unlikely in my opinion.

It is Dtpa-FE%7. With a couple of days past and after water changes, it is not getting better. I thought it would be gone after some WC if it is a Fe issue. So I think it is bacteria bloom.

Thank you for the advices, Now I think it is a bacteria bloom too. But very confusing because it does not seem green to me. It is somewhat white-ish. I can not tell the exact color.

It is very dissappointing feeling when you think your tank is just starting to get better.

Looks similar to what I had. Even with tons of back to back water changes, zero nitrite and ammonia it persisted in my tank. I gave up and zapped it with a cheap UV sterilizer and took care of it. Don’t know if what I did was right, but it worked!

If bacterial bloom, add air stone and oxygenate the water.

Did you try a blackout ? I'm gonna try a blackout, wondering if there is any rules of making a blackout, how many days max, WC before or after, cut co2 etc..
