Questions & Answers for Tetra No More Algae Tablets

Question

What can I do to safely remove excess algae from my tank without hurting the fish, algae eater and plant life?

Is using the algae removal okay for my algea eater? Can I just use it less frequently? I've had my tank for 8 months and it's only been the last 2 months that algea has gotten out of control. Will it hurt the fish if the rocks are coated? plants?

Our Algae Control is a great product, but it can be detrimental to your algae eater. Make sure your aquarium light isn't on too long. That will help cut down on algae growth. You can also remove the decor, scrub it with water, and let it dry to kill the algae. If you have further issues, contact our customer service department at 1-800-526-0650.

Hello,

Yes, you can. Please be sure to follow the directions carefully, do a water change the day before you dose, and remove your carbon filter from your filter for 4-6 hours, then place it back in the filter. The filter should run, even without the carbon filter in it.

Regards,

The medication will remain active as long as you've not put the carbon back in, which will neutralize the tablets. Is your algae gone? Do a good water change, put the carbon back in, and let it all filter through for a few days. Then change the filter cartridge and you should be fine.

Algaecides are meant to be slow moving products. This is to keep the fish safe, as killing algae can reduce oxygen levels. Expect it to take 12-24 hours to start working and 48 hours to completely clear the tank. Depending on your water chemistry and the amount of greeness, it may require a second dose.

No, we do not recommend it for aquatic turtles since they can absorb chemicals through their skin. Over time, this can cause problems.

We recommend you wait 3 days before retreating along with a 15-25% water change between dosings. Results varying depending on the severity of the algae in your aquarium. Although the No More Algae does treat the "brown" (Synedra) algae, it is recommended that you first remove as much of the algae off the glass and decor prior to treating for best results.

You didn't have to take the fish out. But since you did, put the fish back as soon as the fizzing is over.

Depends on how large a water change you did. If you just did a 25% one, you can wait a few hours for it to settle down, then treat. If you did a complete one, you cannot treat for 3 months as it would be considered new again.

In a diluted form, it will not bother them. We usually recommend keeping pets away for at least a couple of hours to ensure it is fully diluted. After that should be fine. Same with your child. However, the product is in the water for a total of three days. It gradually dissipates over that time, but it definitely is present, so if you prefer to wait till it is totally gone, we would recommend three days after your final dose.

That would depend on the type of fish you have, whether you have crustaceans or molluscs and how long the tank has been set up. In general, we would recommend 1.5 tablets.

I have treated tank with No More Algae for what I believe is red algae.

The algae appears to have changed color but remains on top of the gravel and on flat decorative surfaces. Filters have not been replaced as yet. Do I stir up the gravel, retreat the tank?? Help

That depends on how many treatments you have done. For problem algae, you want to treat every three days for up to three treatments. If you have done all three treatments, you have one of two issues going on. You could have very soft water, in which case, the product will not be as effective and you may want to do a water change, and add some buffer, then try another round of treatments.

However, from your description, I suspect you have cyanobacteria. This is only affected by erthromycin, and you would need to treat with this antibiotic to get rid of the red "algae".

Question

What if you have black algae?

It is hard and stuck to the sides of the tank. I have tried scrubbing it off with no results.

I also have a pleco and I want to make sure that using an algae fighter won't harm him.

I would first vacuum and change the water, wait several hours and test the parameters, especially nitrite and nitrate. In my experience, black algae usually occurs in tanks that don't receive frequent changes or vacuuming, and can be hard to eradicate. If you find that the gravel is really dirty, wait a few days, and do another partial change. Never change more than 25%.

After the second change, wait a few more days, and dose with the Algae Control.

In regards to the pleco, he will be fine with the Algae Control. Just feed a single algae wafer every other night to keep him happy or a thin slice of cucumber, with the skin still on it. Stick a toothpick through the cucumber, and into the gravel, to hold it down.
