Gets rid of red slime algae
Have been getting a lot of persistent red slime algae in the fish tank and just a capful of this solution helps me keep the algae in check. I add this to the tank every time I do a water change. There are clear instructions on dosage on the back of the bottle and you can adjust it as per the size of your tank. I only use a capful for my tank making it cost effective. Also It has never had an adverse effect on my fish's health and it is shrimp-friendly too which is the most important thing for me. My fish are happy after using this product. Overall, this is an effective solution to get rid of red algae and keep the water looking crystal clear for weeks.

Impressive results
I’m a bit wary of algicides and have never had a good result before. However my terrapin got an unexpected and aggressive bloom in his tank over the new year so I thought I’d give this a go. My first reaction was how small the bottle was! Ok obvs I didn’t read the description properly. However, after taking a few measurements to calculate the water volume (the tank is only ever around half full) I used a shot glass to measure the dose and poured it into the stream of the most powerful filter pump I have. By the following morning most of the floating bubbly stuff had gone. Two days on and nearly all the waterborne stuff has gone. I have honestly never found a chemical before that works so efficiently, my terrapin is completely happy and despite being in winter hibernation mode took a small feed yesterday now he can see it floating. I definitely recommend this product and wish I’d taken before and after pics to show you!

Worked for While
My fish tank was suffering from really bad algae. I tried this and it did clear it but can't back quickly. I eventually solved the problem by moving my tank to a shaded area in the room

Patience is key
“Good at tackling algae, but requires patience and good tank habits.” I’ve used Tetra AlguMin several times in my freshwater aquarium. It’s very easy to dose — just measure 5 ml per 10 litres — and it disperses quickly without clouding the water. Within a few days I noticed most green algae on the glass and decorations starting to die off, and after a week or so the tank looked noticeably cleaner. That said, it’s not a magic bullet. Black beard algae and some stubborn blue-green patches didn’t disappear completely after the first dose. I also had to manually remove dead algae and make sure my filter and aeration were running well, otherwise oxygen levels dipped a little. Overall, AlguMin is a good product to control light to moderate algae growth if you combine it with proper maintenance (water changes, balanced lighting and feeding). I’d recommend it as part of a broader algae-management plan rather than a one-time cure.

Algae returns!
Algae still comes back so you need to use it regularly which makes me concerned for the fish. Need to try something else.

Early days but it’s already looking good
Early days used Algumin with a water change on Sunday & already seeing a difference in our aquarium. Water remaining clearer very little build up of algae on the glass. As I say early days but it is looking positive.

Produit parfait, enfin un traitement efficace contre les algues
Complètement et immédiatement efficace contre les algues dans mon petit aquarium, je suis convaincu, et je recommande ! L'eau redevient et reste durablement cristaline, et les poissons ne souffrent nullement de ce traitement, bien au contraire ils nagent dans le bonheur !

Prodotto efficace, richiede solo un po' di pazienza
Avendo l'acquario davvero pieno di alghe, ho deciso di provare questo prodotto. Dopo due settimane di utilizzo i miglioramenti sono ben visibili, anche se le alghe non sono ancora sparite del tutto. Visti i buoni risultati iniziali, farò sicuramente un secondo trattamento per eliminarle completamente. Lo consiglio, funziona bene!
