Blue Exit, 250 ml

This did not appear to work at first after the suggested dose and treatment phase. I guess my outbreak was quite serious, it was everywhere. I noted that in the instructions it says you can increase the dose or use it for a prolonged period. I decided to go for the prolonged period and just kept dosing the regular amount each day for about 12 days. This approach worked. I also made sure to remove any floating algae each day too. I leave the snails in my tank as they are good for cleaning algae and I think they enjoyed the dead algae ! Whilst dosing, due I think to all the dying algae the water became very cloudy. But after about two weeks all the blue-green algae has gone and the filter has caught up so that my tank looks pristine again. So in summary; if you do it right this product does work.

I chose the item as it had good reviews and wanted something that actually worked. Why did you choose this product over others?: I had tried around 4 different products previously and they hadn't worked. This one has made my algae complete dissappear.

I was a bit disappointed the first time I used this product. The slime reduced and almost disappeared. After the 14 day period, I carried out the normal water change and filter maintenance, but the slime gradually came back as bad as it had been before the treatment. I left it alone for a week to give the fish a break from the treatment and then tried again. This time I gave a slightly higher dose than was instructed and I turned the aquarium lights off for 2 weeks. Now there is no sign of the slime. I think turning off the lights was what helped the most. It doesn't say that in the instructions, but it makes sense as the cyanobacteria photosynthesise. I should have thought of it before. Fish are happy as am I! I have read that people put a precautionary dose in weekly or monthly. I am going to try that for a while.

Had a bloom of blue algae in the tank. Couldn’t shift it. Then I bought this stuff. It doesn’t happen over night but stick to the instructions and it starts to work. Has not affected anything including the shrimp

Just make sure you read the reviews! The instructions on the bottle aren’t detailed. I read everyone’s reviews and made sure I didn’t make the same mistakes. I have a 45litre tank and my case was quite bad. I dosed every day for two weeks, lights off for the whole two weeks, i helped by removing bits of algae every day myself. Didn’t do any water changes. This is where I'm at now. I’m going to water change today but I’ve notice a brand new batch of baby shrimp so I’m worry to change the water incase they get sucked up haha I’m going to dose once a week now as a preventative but all the algae is gone the tank is looking super clean! So it works just be thorough!

I had a severe blue green algae attack several years ago which I largely cured though ever since I have had a very minor persistent problem. I have never managed to totally erradicate it and still see it around filter outlet, on electric wires and on older plant leaves which I have to remove every couple of weeks. This is time consuming so I thought I would try this to see if it would improve what is only a minor issue. Well, for the first few days when I added the product on a daily basis there was a definate improvement. I even started to see lighter brown patches on my bogwood, suggesting that I had BGA there too and hadn't even realised! However, once the the dosage was completed, the instructions are to then leave it with no water changes for 10 days, which I did. During that time there was no further improvement. The instructions at this point are vague as they say that you can continue the doseage for 'a few more days' even up to 'double the dose'. Does this mean you can continue putting in twice the amount each day for an indeterminate number of days or does it more likely mean that you can continue putting in the same amount for up to another 5 days? I tried the latter. There was no further improvement and since I resumed normal water changes the BGA is certainly worse than it was before. It began growing on the new plant leaves not just the old ones, so most of my plants have now been killed or have had to be removed. During this period I did add a weekly dose as a preventative, as stated in the instructions. So, the fact that it worked initially suggests that it might help in the case of a severe attack of BGA, but for my milder issue it ultimately seems to have weakened my plants and allowed the BGA to take hold, making the situation worse. Accordingly I would say, use this only if you have to and all else has failed but don't use as a preventative or where you only have a minor issue.

It doesn't work.

My 80 litre tank has suffered cynobacteria for years. I tried everything to rid the tank of it. Blue Exit worked within 10 days and has been completely free for several months. Aquarium cleaning and regular water change is so easy now. Blue Exit is well worth the cost. My fish are happier too.

Hola, he visto reseñas negativas sobre este producto y puedo decir con seguridad que a los que no les a dado resultado este producto es porque alguna otra cosa les falla en el acuario. En mi acuario hasta hace 4 años tenía una plaga de algas del tipo alga roja, estáva totalmente de esperado, no avía ni una sola piedra o planta que no estáva plagada de ellas. Avía intentando con varios antialgas, tipos caseros, vamos de todo y no avía manera de eliminar las hasta que no probé este producto. Lo encontré por casualidad buscando por los foros alguna solución a mi problema, haun que sinceramente pense que será otro intento fracasado. Pues no. Es 100% efectivo, esto si, no hace efecto de hoy a mañana, el tratamiento tarda 4-8 semanas, al principio no se ve ningún efecto y uno se sigue desesperando. En mi caso después de semanas de tratamiento seguía viendo las algas hai, pero me dava cuenta que no salían nuevas y heran de color más claro, y un día metí la mano como hacía siempre para ir quitando las una en una y sorpresa, las algas estaban muertas, se dezasian en polvo por todo el acuario. Llevo ya unos 3 años que no he tenido problemas con estas algas. He dicho al principio que al que no le funciona es por algo que tiene mal en el acuario, porque la principal razón por la que aparecen las algas es por el mal mantenimiento del acuario y por mucho que echemos antialgas se irán quitando y aparecerán una y otra vez, así que hay que partir de hai, arreglar lo que no está bien en el acuario. Para que todo vaya bien obligatorio agua de osmozis, muchas plantas, mucha luz y sifonado del fondo todas las semanas.

Es a diferencia de otros antialgas , efectivo con cianobacterias, alga barba , pincel y unicelulares, en combinacion con easy-carbo u otras fuentes de carbono( excel o glutaraldehido) , no daña los plantados. (Musgos algunos sufren ) Un producto bueno, bonito y barato.

Ho avuto un periodo di squilibri in acquario. Prima un esplosione algare, risolto quello ho avuto formazione di cianobatteri. Fatti i trattamenti seguendo le istruzioni ho avuto la rimozione di circa il 90% dei cianobatteri, ho quei di rifatto il trattamento a distanza di 2 settimane e c'è stata una rimozione totale.

A fonctionné parfaitement pour moi dans un aquarium de cichlidés (500l) envahi de cyanobacteries

duur, maar het werkt
