Q: I have a black fuzzy stuff on my plants will it get rid of it

We had the same problem with Black Beard Algae, which is one of the hardest to get rid of. Especially because algae eaters don't like this. Now we have only a few spots here and there occassionally, but they never get bigger than 1mm, previously they were up to 5cm in length and covered large areas. We have 3 very strong lamps illuminating too. What I have learned: 1. Water balance - this is where this and other similar products can help. They need a rough substrate or large biological filter to work as well. 2. Healthy living plants - you need enough plants to remove all other food from the water. Give them enough micro-element fertilizers, so they have an upper hand against algae. Grow at least one fast growing variety, which you cut back weekly and remove all excess plant food with this. 3. Algae and waste eaters - against algae the best is to have one Common Bristlenose Catfish (Pleco) aka Ancistrus sp, which is the smallest this kind of fish. This doesn't like Black Beard, but don't avoid this either, if there is any kind of other edible material in it. For other algae and waste you can have Amano shrimps and/or Assassin snails. Assassins will get rid of small unwanted snails as well. 4. Hydrogen peroxide - if you have big bushes of Black Beard, very carefully use pipette underwater to put a drop of food grade H2O2 in the middle of the bush. This reacts with photosynthesising elements of the algae and kills this. Keep fish and other animals (incl snails) in the other end of the tank for a few minutes and dont use too much of it. For 200l tank I have used up to 5ml 10% of H2O2/hydrogen peroxide. It is important to keep lights on and fish as far as possible, as this may burn their gills. This would be good to switch filter off during the treatment, depending of your tank layout. Too much and direct peroxide can kill good bacteria too, if this happens, use this product (or similar product) to replenish the bacteria. I hope this helps.

Q: Does it treat brown algae as well ?

Yes, we have no data to suggest that it doesn't

Q: Every week my fish tank keeps going green where am i going wrong

Do you clean the inside of the glass on the tank because the envii aquarium klear won't work on its own . I also recommend changing the filters once a month as directed by filter manufacturer . Hope this helps .

Q: Is this safe to use for my yellow bellied slider terrapins??? It does say all types of aquatic s fine but i didnt want to assume

I have shrimps so only used half of what it said. Tells you on the back instructions. They are very delicate shrimps so I suppose it would be fine with yours.

This Stuff Is Like 🎩🪄🔮

Before choosing this product I had looked at plenty of others & thought they all say that they do this & do that. So I took a punt on this one, as they say the proof of the pudding etc (I do not recommend anybody trying to consume this product as it won't end well!)After a week, my aquarium always used to get a big build up of algae on the live plants, ornaments, air brick & filter as well as on the glass, which was due to its location & getting direct sunlight through 2 Velux windows (aquarium can't be moved elsewhere out of sunlight due to having limited space).I half emptied the aquarium l, cleaned plants etc but not the glass & refilled it & added 10ml as directed.After a week the results were astounding!! No return build up of algae on anything in the aquarium & after a 2 week of treatment, the algae has not returned! I thoroughly recommend this product!I am using 10ml weekly & it contains according to the labelling, natural ingredients that do not harm the fish, pondlife or plants.I'm so glad I took a punt as I was apprehensive that I would work & have found out it doe so amazingly well!

Brilliant Product - Envii Aquarium Klear

Very highly recommended, it’s a miracle product. My aquarium was really quite bad, with green algae, as it is positioned by a window. I now keep the shutters closed to stop the sunlight getting to it and I treated it with 1 5ml application of this product and it is crystal clear.

No happy

As I read "Brandenvii Liquid volume 4000 Litres Item form Liquid" I believe I was buying 4000ml not 500ml. False information. That being said, I used 20ml in my 200+L tank and it cleared up within 2 hours, looks crystal clear. Been using interpet quick clear and it only made the water red.

This product works great to get raid of all the algae im your fish tank and also some other bad bacteria in the fish thank that can manifest on the glass expecially if your fish tank gets one sun rays or if u have live plans. I recommend this product.Algae control:Works fast.
