Help with cloudy water

I'm scratching my head on this one...

My 75 gallon has been set up for just over two weeks. I took down 3 smaller tanks, and combined them into this one tank. I was able to use the bio media from my smaller tanks in my new Sun Sun 304b.

The tank is co2 injected, and I started dosing with PPS Pro at 1 ml/gallon after one week. On day 5 of PPS dosing, my tank started to turn cloudy. It appears to be a white color, with fine particles suspended in the water column. Despite running the sunsun skimmer, the tank has also developed a film on the surface. Filter has a tray of course sponge, a tray of fine sponge, tray of bio media, and tray of purigen.

Water test show no signs of ammonia or nitrite, with 30 ppm of Nitrate.

Any ideas on what caused this tank to cloud?

I completed a 30% water change, but it didn't change clarity much. Should I stop the PPS dosing? Did I start too soon? Is this related to the cloudy water? Any help with this would be GREATLY appreciate!

You are having a bacterial bloom. It will go away without causing harm. The trigger was probably your use of substrate from earlier tank releasing a lot of nutrients. Clean the filter media for faster action.

If you have a choice, you have a problem, till you elect your choice. No choice, no problem, only consequences, learn to live with them.

Thanks, I was wondering if this was a possibility. The substrate is new, washed, black diamond blasting sand. Only the filter media was reused. The plants, however, all came from previous tanks. The driftwood is also new

The sunsun filter has a UV light, I've been running it for the last 24 hours, things appear to have not changed.

I'll continue to wait it out.

Try increasing co2. It cleared my tank up. Not sure if it will help yours.

did you use a PH proper in your 30% water change? and does it look like smoke coming out of the sub-straight?

i had it react with the sub-straight and had to redo the tank... twice... wont ever use anything like that again!

Yeah, it's most likely just a bacterial bloom.
If it was debris from the substrate or whatever it would of been cloudy right away, and the cloud particles would either collect in the mechanical filtration or settle on the bottom of the tank if heavy enough.
You mention no ammonia or nitrites so it's not a mini cycle so you must just have a small bacterial bloom.
Your cloud isn't that bad at all and will clear up on it's own within a few days.

Things that might speed it along is keeping the mechanical filtration a clean to remove collected organics, and you could vacuum (not necessarily water changes as tap water has some dissolved organics -TDS-) any debris within the tank and remove any decaying leaves. All about removing the decomposing organics, which the bacterial bloom is feeding/multiplying from. I believe the Purigen is helping absorb some of the "dissolved" organics, but to what extent I am not sure. Once the tank matures/establishes more, the bacterial blooms won't be appearing if things are maintained.

Thanks for these links, now it makes sense. I suppose I've just been fortunate enough to avoid these blooms in my smaller tanks.

Would you recommend I continue pps dosing while waiting out the bloom?

Just disregard the bloom. Follow the routine.

Thanks for the help. I rinsed my filter pads in dechlorinated water added a bag of purigen along side the other one.

Increased water changes occasionally can help shorten a bacterial bloom but the best bet is to just ride it out.

I wish I would have thought to take a picture of the one time, where i reused some wood on a new setup. The wood had been dry and in the garage for 6 months after a seam on the previous tank went.

I tossed the wood into a 2/3 filled tank to soak and sink. A week later the water was milk colored and the wood had a film covering it all. Could barely see two inches into the tank.

I turned the filters on. Changed out most of the water, added in the substrate, and tossed in the plants. A week later it was crystal clear... Then came the diatoms for the next two months from the new tank.
