Is my brand new aquarium experiencing a bacteria bloom after just 24 hours, or is it something else causing the cloudine

[hush]

Just got my new tank up and running, and I'm a bit concerned. The water is still super cloudy after 24 hours - it's like a bacteria bloom, but it seems too early for that, especially since it's a fresh setup. I seeded it with 1/3 water from my old tank to kickstart the good bacteria, but now I'm wondering if that was the right call.

I'm trying Seachem Flourite Black for the substrate for the first time, and it was a bit messier than the Tropica Aquasoil I've used before. I gave it a good rinse before adding it, but still. My 50-gallon tank cleared up instantly when I set it up a few months ago, so I'm not sure what's going on here.

I'm running a cheap nano tank filter from Amazon, which has the right GPH flow rate, but maybe it's just not cutting it. Is it a bacteria bloom, or is my filter the problem? I'm thinking of a few options:
1. Leave it and hope for the best?
2. Grab some water clarity chemical?
3. Do a water change?

Any advice would be appreciated.

I've seen this before, and it's usually just substrate dust. I'd start by giving the glass a good wipe down with a clean sponge. If it's still cloudy after that, I'd probably drain and refill the tank with some fresh, dechlorinated water.

Sounds like new tank syndrome, look it up.

Bacterial blooms in new tanks are quite common, and it's essential to understand they're different from the beneficial bacteria we want to cultivate. The key difference lies in their food source - bloom bacteria thrive on carbon-based nutrients, whereas filter bacteria feed on nitrogen-based nutrients. Another distinction is their habitat: bloom bacteria are free-floating in the water, while filter bacteria reside in the biofilm on surfaces. Furthermore, bloom bacteria multiply rapidly, whereas filter bacteria multiply at a slower pace.

When we set up a new tank, we introduce water that has been treated with chlorine or chloramine to kill bacteria. However, this treatment doesn't eliminate all bacteria, and there's still organic matter present in the tap water and in the plastic components of the tank. Once we add a water conditioner to remove the chlorine or chloramine, the bacteria in the water are no longer inhibited. The bloom bacteria then start feeding on the available organic matter, rapidly multiplying and causing the water to appear cloudy. Fortunately, as they exhaust their food source, they die off, and the water clears. The duration of this process varies from tank to tank, taking anywhere from a few days to a couple of weeks.

It's also possible that the cloudiness is caused by dust from the substrate, which will eventually settle to the bottom, allowing the tank to clear. Adding extra filter floss to the filter can help clear the dust, but it won't affect a bacterial bloom.

If the cloudiness was there from the start and didn't develop over time, I'd say it's likely super fine dust. Some substrates just produce incredibly fine particles that can pass right through filter media, leaving you with a persistent cloud that can last for weeks. Unfortunately, aquarium filters aren't designed to handle such small particles mechanically.

To address this, I'd recommend draining the tank as much as possible and refilling it with treated water. Use a siphon and a dish plate to fill the tank, taking care to minimize disturbance to the substrate. Also, thoroughly rinse the filter media and give the enclosure a good flush.

One thing to avoid is wiping the glass if you suspect it's sand dust - it can scratch your tank, and it's especially problematic with acrylic tanks.

I'd say just be patient, it's still early days for your tank. The cloudiness will likely clear up on its own as the cycle progresses. It's normal for new tanks to go through this, and it doesn't necessarily mean anything's wrong. Just give it some time and see how it develops.
