When I first set up my 75 reef flat I had lots of flow, and yes you can swim a fish to death .

How much is too much flow planted tank?

In a planted tank a flow of around ~10X turnover of tank volume is my recommended ‘target’ flow rate to achieve optimal circulation of O2/CO2 – and for delivering nutrients to plants. ​ Spending on a filter with good flow negates the need for extra pumps in the tank.

Can fish have too much flow?

High flow and fish:

Like us, fish need exercise. Too weak a current will make fish lethargic, too strong and they will keep hiding to avoid the force. The strength of flow needed also varies depending on what fish you have. Fish such as Batfish and Lionfish cannot handle strong currents .

Do fish like flow?

Depends on the fish . My tangs love high flow. They go right in front of my power heads and “ride the current” lol. Like Reeferdood said, if they don’t like the amount of flow in one area, they can always go to another where the rocks break up the flow a bit.

Can too much oxygen kill your fish?

The suspected killer is a rare but deadly quirk of nature: Too much oxygen in the water. “ Usually lack of oxygen in winter causes fish kills ,” said Donn Schrader, Department of Natural Resources fisheries specialist. “In this case it looks like the supersaturation of oxygen in the fish killed them.

Can you have too much filtration in an aquarium?

You can’t really over-filter an aquarium , but it’s fairly easy to under-filter one. Most aquarium filters are rated according to how many gallons the aquarium holds.

How much flow should a fish tank have?

A good rule of thumb is to select a filter with a flow rate at least six times the volume of the tank —so for a 30-gallon tank you want a flow rate of about 200 gph (gallons per hour).

How do you know if coral is getting too much flow?

How much flow is too much reef tank?

This week we are answering one of the most frequently asked questions from Week 9: “How much flow do I need for my tank?” There are a few variables to this as it’s not an exact science, but in general we recommend 20 to 40 times your display tank’s volume .

Can too much flow cause algae?

However, too high a flow rate can also cause algae to form in the aquarium , as too much nitrate is now absorbed by the filter and therefore too few nutrients for plants are contained in the aquarium – a nutrient deficiency that promotes the growth of algae.

Can an aquarium be too heavily planted?

Generally, an aquarium can not have too many plants . As long as your fish have space to swim, you can’t really overdo plants. Even thick plant cover simulates the natural habitat of many fish, especially small community species like livebearers that are typically prey in nature.

Does an aquarium need flow?

Moving water at the top of the aquarium is important because it prevents oily biofilm from developing on the surface and encourages good gas exchange, where carbon dioxide (exhaled by your fish) is released into the air and new oxygen (for the fish to breathe) enters the tank.

How do you tell if current is too strong for fish?

You should check to see if your betta is swimming with ease. When the current in your tank is too strong, your betta may look like he’s struggling to swim . It almost looks like he’s getting blown around in the wind.

What fish can live in fast flowing water?

Try small danio species, like pearl danios . They should enjoy flowing water. Dwarf neon rainbowfish might also work.

Do Oscars like fast moving water?

But to put it simply: You can find oscar fish pretty much anywhere in the Amazon River Basin. They typically live in low-flow, slow-moving white waters, which act as perfect hiding spots from predators- especially if there are greenery and branches.

Why do my fish like swimming in the bubbles?

Yes, some fish do like bubbles.

Bubbles can also be a sign that there is enough oxygen in your fish tank . Only when there is proper aeration can fish create tiny bubbles. Further, these bubbles help in the oxygenation of the water as well.

Can I turn my air pump off at night?

Air Pump Separate From Filter

If you have just a good old air pump that is separate from your aquarium filtration unit, then you should be able to turn it off during the night, at least for a few hours from when you go to bed to when you get up .

Can Airstone kill fish?

No, you didn’t kill them with the airstones . What I was getting at was only if you had ammonia to begin with would pH be a factor, and it would have needed to be low before you started oxygenating the water.

What happens if your filter is too big for your tank?

As long as the filter will move the entire volume of water in the tank it will be good enough. You could put a filter rated 2x’s the size of the tank or 10x’s the size of the tank, it will still only grow enough bacteria to handle the current bio-load of the tank and no more .

How high should filter be in fish tank?

Keep an eye on how much water is in your aquarium—most filters need the water level to be about one inch from the lip of the filter .

Should you turn off filter when feeding fish?

If your filter is pushing water downwards then it can be a good idea to switch the filter off during feeding to prevent this — just be sure to switch it on again afterwards! Many fish foods have a mixture of densities in the one pack, so some will float, some sink rapidly and some slowly.

What is GPH flow rate?

Flow is the volume of water measured in gallons per hour (GPH) or gallons per minute (GPM).

Do torches like high flow?

The best placement for a torch coral is in a location that gets moderate water flow and moderate-intensity lighting. Just like Goldilocks, you don’t want the lights or the water flow to be too hot or too cool. You want them just right.

Can Frogspawn handle high flow?

You’ll want to aim for a moderate amount of water flow with this coral, but a touch higher can be tolerated if absolutely necessary (if it’s necessary for other life in your tank for example). Keep in mind that high water flow can have a negative impact on growth and polyp health.

Why is my torch coral retracted?

The coral is situated in the corner, nearby the heater, when the tentacles were at their longest the two heads may have touched the heater , causing them to retract.
