Tetra CrystalWater - eliminates clouding from aquarium for crystal clear water, 250ml

Update.. I have now used this several times with fish in my pond its pristine now my biofilter is good mashes the pictures on here look awful lol. I make sure my KH is high enough and no signs of distress in my fish at all just crystal clear water.......I have seen the reviews saying this killed all the fish however my review is based on use in a new wildlife pond which currently has no fish but lots of tadpoles and baby frogs and nothing died. Having waited to no avail for my all in one filter and UV to clear my pond i decided to try this to get the water clear before adding any fish .. WOW... I was impressed. I mixed the correct dose with pond water in a watering can and evenly spread round the pond. It has a slight milky hue for a few moments but literally within about 10 minutes i could see the pond was full of suspended clumped particles. 24 hrs of filtering later and the difference in water clarity was amazing. The gunk that i rinses out of my filter 2 days after use was quite shocking ewwww Only criticism i can have is amazon sent me a German version with not a single word of English in the instructions so i had to go to tetra website. I also cannot find anything that tells you how frequently you should use this... The. Website however is very very clear that your KH (carbonate hardness) must be above a certain level to use the product so i suspect this absolutely floors your PH if its not buffered by a high enough KH which could explain the fish deaths. Easy enough to avoid any dramatic ph change by ensuring your KH is 6 or over as per the tetra web page instructions. My before abs x after pics don't do the result full justice to be honest. I will use this again.

I was sceptical about this product about how good it would actually be...well I was amazed..used as directed, the pond water became absolutely clear after2to 3 days...fabulous product

My pond water was very green and I initially didn't expect or see much difference after only one treatment. I followed up with another dose a couple of weeks later and the difference is pretty amazing. I still have enough left for more treatments and would definitely recommend this product.

Impressed. It really has worked. I think it needs to be added before the water gets too bad as used it before and it wasn't as good. The water was murky and couldn't see the bottom, but within 12 hours, pretty much crystal clear.

Hasn’t cleared the water in our pond.

Good quality great value for money

This product worked brilliantly, my mini pond water was cloudy and smelly but within a day the water was clear and the smell went away. I don’t have and fish in the pond but I have plants and they were fine

May need several applications, still quite cloudy pond water No measuring cup.

parfait

Funciona 👍🏻

This product works quite fast and doesn't trouble the fish

Liquidò perfetto per il mio laghetto. Tiene L acqua molto pulita. Ogni settimana alla pulizia del laghetto ne metto la dose giusta e vado avanti così ogni settimana.
