Can anyone tell me the cause of greenwater algae? How do you prevent it. And also, during a blackout, do you dose ferts?

Usually high N will and low P with high light will cause that. While u blackout, no dosing of fert.

Nitrogen...depends on the type. Nitrate even in high amount doesn't cause that but ammonia even in relatively low amount will. Phosphate does not contribute anything nor is it related to this algae.

Ammonia is the trigger to greenwater.

Plant heavily, take care of the plants needs (CO2, NO3, PO4, K, traces, GH(Ca/Mg)) and low to moderate stocking of critters will prevent that. Always do large water changes will uprooting plants or whenever you stir up the substrate.

Don't need to during the blackout.

Think my tank's having something similar to yours. Changed bio-media + new fishes. So im guessing bacteria bloom, followed by the excess ammonia causing green water, creating our super-cloudy water hehe. My fishes doesnt seem affected though.

The most efficient way for removing green water is using UV light. Loan/rent one from a friend what so ever, it should all go in 3-4 days time.

well its a small tank, 10 gallons about 38 L

I don't see any problem, just run a small filter to push the water into the UVC (you know how it looks like, right?), and make a return flow.

What would the price be like, for the cheapest UVC?

I think its near $100, can't really remember the price.
You won't really need one for one. Loan/rent it will be a more economical option.

Bought Azoo Green Water Remover. Not sure if u can find it in America, but will update with results.

[kniveswood]

So here are my results so far:

5th April night: Dosed 6ml of Azoo Green Water Remover instead of the recommended 7ml (For 70l of water)

6th April night: Water still looks cloudy and slight greenish. Added another 5ml of Azoo. Although bottle says it's ok to dose again in 24hr, to be safe i did 30% water change 1 hour later. Water looks much clearer after water change, though not crystal clear but very acceptable. Fishes all look fine to me.

My tank:
2ft tank
Atman hang-on-back filter + air stone
6 juvenile angels
1 adult angel
4 threadfin rainbows
2 siamese algae eaters

So it seems to be working for my setup. Will update if the green cloudiness comes back.

7th April night: By my standard, i consider my tank now crystal clear! I believe bb has taken over the greenwater's duty in converting ammonia/nitrite. I also believe my Nutrafin Cycle helps too.

8th April night: Still crystal clear!

I'm on my 3rd day of blackout running diatom.

I'm on my 3rd day of blackout running diatom.

Ahh so how is it? I believe it should work very well.

[turtlehead]

just changed out 20% water looks clear with only the tannins one more day and morning and I will do a 50% and back to normal schedule HOPEFULLY! leaving the diatom on for 10hours tomorrrow in case.
