Not if used as instructed on the package, no. Make sure you have a filter system in place. It will not work correctly without one and many betta people do not use filters.

Question

Why is the aguarium water green?

My algae eater is in a 29gal tank alone. The water is green. No algae on the aquarium itself. I can't get the water to clear. I took sample to pet supplies plus and they said everything is fine except the water is hard. However, the algae eater keeps going to the top and sucking air is what it looks like he's doing. Pet supplies said to put distilled water in and change 75% of the water. Can anyone tell me what to do. His name is Ishy and he's 6 or 7 years old. I bought a new tank (everything is new) and it happened in this one too.

If Ishy is really large, like around 12" long, he is due a larger tank and may be having oxygen issues. Make sure you vacuum his tank and replace 25% of the water once a week to keep the amount of dissolved organics low. To help clear the water in the meantime, add Tetra Safe Start. It will take a few days, but it will eventually clear it, naturally.

If you cannot buy a larger tank right away, the water changes and a larger filter or an addition of an air pump will help in the meantime.

Hello,
Yes you may use it with fish. However that being said, precautions must be taken to ensure the chemicals don't indirectly affect the fish. This can happen when you have a lot of algae in the aquarium that dies and starts to break down rapidly, which can cause rapid deterioration of water quality, in turn harming the fish. To prevent this, always do a cleaning of the aquarium prior to using algae chemicals. Try to remove as much of the algae as you can by hand. Flush out the algae with a partial water change. Don't take out too much water as this can remove too much of the good bacteria in the aquarim. so it is wise to never remove more than half of the water usually. If your aquarium is new you don't have much of this stabilizing bacteria so you don't want to use algae chemicals at all for about a month.

Another thing to remember is that using chemicals can lower oxygen in your aquarium temporarily. Make sure the filter is running (without the carbon in it) and it would be a good idea to drop an air stone from an air pump into the aquarium. If you see fish gasping at the surface for air that means they need more oxygen. Aquariums that are overstocked with fish are much more vulnerable to this problem. That is one reason it is so important to have a properly stocked aquarium.

If you have done a cleaning of the aquarium and have provided aeration, and your aquarium has been established for at least a month, then you should be fine using the Tetra algae control. It would be wise to also try to determing the root of the algae problem. It is always excess nutrients or excess light. Try to find out which of these problems or if both of these things are causing the algae, and then eliminate the problem.

Hello,

Canada has some pretty stiff restrictions on chemicals being shipped over their borders. I am not sure if this is one of the chemicals that is not allowed in Canada or not. Petsmart stores do carry it, if you have not checked there yet. Otherwise, visit the dealer locator on our website and enter your postal code to find stores carrying our products near you.

Once every three days for up to three doses, over a 9 day period of time, to treat an actual problem. As a preventative, we recommend once a month, or dose as soon as you see algae developing.

Turtles can produce a large amount of waste each day. Careful vigilance of the land section and a good filtration system on the water section will help avoid hygiene headaches. For the most part, their daily care is the same. Give them a fresh bowl of water each day and remove waste on a daily basis. If it is an aquatic turtle, change the water once a week at the least. Most will not have any gravel in the bottom of an aquatic tank. It only increases the amount of labor on aquatic turtles. Keeping a clean environment will enhance the turtle’s health and ultimately its life.
Thanks.

The water in my tank is green and cloudy. I bought Algae Control but I have a large Pleco. Will this harm him?

I vacuumed the tank 2 weeks ago and also did a 1/2 water change. This helped with most of the green water problem, but I still have somewhat green and cloudy water. I have a 32 gallon tank with only 1 large Pleco. I want to fix this problem before I add other fish. Will the Algae Control help this problem?

Tetra Algae Control is safe for freshwater aquariums for fish and live plants that have been set up for more than three months (not for newly established aquariums less than three months old.) Please make sure to remove the carbon filter cartridge while using this product (return after 6-8 hours has passed after adding Tetra Algae Control) but continue to run your filter the entire time. The proper dosage is 1 drop per gallon of water or 1mL per 12 gallons of water. Please follow instructions closely for maximum effectiveness of this product to combat your green (algae) water.

Whenever adding a chemical other than a water conditioner, you need to remove the carbon filter so the carbon will not pull the chemical straight back out of the water. In this case, leave it out for 5 or 6 hours, then put it back. The chemical will have a chance to begin to destroy the algae, and then when you put the cartridge back, it will pull out the dead and dying algae. Follow these steps for any dose of algae control.

It will work on most types of algae. With BBA, you will need exceptionally good water quality and a high level of CO2 (around 30 ppm if your fish can handle it) to wipe it out.

Once you replace the filter, it can take up to 3 days to clear. This is a slow moving product due to the fact that we do not want to harm any fish. Wait 3 days, a full 72 hours. If it has not totally cleared, re-dose. Usually, 1 or 2 doses is all you need, but if it does not appear to be clearing, test your pH, and alkalinity as acidic water makes the product less effective, as does extremely hard water.
