Cloudy tank - 2 months - read all the threads
ok - So I have some form of Super bad Heterotrophic bacteria bloom. I've ready lots of internet articles, followed a lot of the basic advice and still not getting better (wait it out, vacuum the substrate, add "beneficial" bacteria, used Green Killing Machine, lower light levels, change lots of water, don't change water, etc)
Here are the basics:
20 gallon long freshwater
Medium load planted tank (crypts, bucs, java moss, corkscrew Val)
One piece of 8 inch piece of mungwani driftwood
Lightly loaded with 10 Ruby tetra and 20+ Neocardia Shrimp (happily breeding)
TwinStar 650 light on a 8 hour cycle
Water parameters are (almost) ideal. The pH is stubbornly high. I test every 2-3 days with API Master test kit, to look for any fluctuation, but nothing is spiking.
TDS (ppm) 165
The substrate is Black Diamond Blasting stand.
It is an internal double sponge filter, which keeps the shrimp happy, and I have not recently clean it.
The tank was about a month old when the problem started and has been cloudy for over two months now.
The plants were growing nicely before the bloom, but some have started to lose leaves due to the light loss. I recently trimmed all the dying plants to reduce the amount of organics going back into the water. As a fairly new tank, which was lightly fed, there wasn't much bio-load to start with.
I recently tried Seachem Stability but no change.
Water changes are done with rainwater, reminerialized with Salty Shrimp
I don't add any fertilizers or other chemicals that may cause precipitation, and the water motion isn't enough to be stirring up the substrate.
I'm thinking of antibiotics, but pretty sure that will just cause other issues.
Any suggestions beyond the basics? Maybe I should be sending water samples to a lab someplace to see if I've breed the start of the great zombie apocalypse in my tank?
