I have reached a final level of desperation in eradicating that foul nemesis
know as "cloudy green-water". I had done the water changes and followed
through on other practices that I know to be correc, but to no avail. My
water parameters are fine:
150 gallon w/ ~ 612 watts of 10,000k light (JBJ PC and Oceanic PC)
Pressurized JBJ CO2 through bubble counter and eheim diffuser: 3 bubble per
kH 5 degrees
gH 7 degrees
NO2 ~ 0 ppm
NO3 < 20 ppm
NH3/NH4 0 ppm
CO2 seems low. Just out of curiosity, why are you using Carbo+ and compressed
CO2? Seems redundant, not that redundancy is necessarily a bad thing.
Another thing: Especially considering the size of your tank, you might
want to think about
replacing the Eheim diffusor with a commercial or DIY reactor. Diffusors
Yes, the nitrates are a bit high, but that should not constitue green-water
for a 2.5 week period of time. In short, this situation started when I
cleaned the filter media in my EHEIM 2028 (boiled it) and killed off my
That'll do it. I've been able to trace practically every algae bloom I've
had back to a
shift in the nitrogen cycle. I.e., ammonia spike = algae attack. Once
genie is out of the bottle, it takes a while to get it back in.
I am either going to purchase a Vortex Diatom XL or a Tetra UV1 sterilizer.
Which would you guys suggest as the best investment from your experience.
Special note: I have also added Bio-spira (Marineland) to the aquarium on
last week, but to no avail. I know that the Vortex diatom and the UV1 will
work, but what are you ladies and gents putting on your tanks?
If it's a matter of one or the other, go for the diatom filter. It's a
very handy piece
of equipment to have around IMO. I don't think UV tubes are nearly as
The only time mine gets run anymore is on the quarantine tank when I get
