    This is the only product I have tried that actually works, within 24 hours our pond water was crystal clear and has remained so but I bought the large size so will use again if/when necessary. We spent a small fortune on additional filtration for our Koi pond but should have just bought Algorem to cure the algae problem.

    I waited 2 weeks for this to arrive and clear the green water in my pond. When it came I read the small print on the reverse of the front label, and discovered it was not suitable for use in soft water areas as would become dangerous for the fish. I would not have ordered this product if I had been told this.

    I'm not really sure of the difference between Tetra's Algorem and their CrystalWater. I suspect they are pretty much the same product in different concentrations and aimed at ponds and aquaria respectively. Although perhaps Algorem also contains agents that continue to suppress algae. Specific information is surprisingly hard to come by. I'd be interested to hear if anyone knows.

    I'd tried everything to clear suspended algae from my 1,000ltr formal pond. I mean everything, from barley balls to dye and all points in between. Kept trying, but was pretty much resigned to more water changes than are practical or healthy for the inhabitants. Then I tried these products. I swear that 12 hours later the stuff had even cleared a lot of the algae from the gravel and walls. If I'd found this stuff five years ago I wouldn't be planning a full drain down, strip and repaint to restore the walls to their former white concrete glory.

    A tip though. Be totally clear about the way the product is supposed to work. This stuff doesn't do the job itself, it enables your filter to do the job. Think of it as the brush to your filter's dustpan. So thoroughly clean the filter before and after application. Goes without saying that filter media should be rinsed in a bucket of already extant pond water (which should then be discarded, possibly over your plants, which generally love fish filth), otherwise you risk waving goodbye to generations of helpful bacteria.

    Using this (or CrystalWalter) in a sulky pond is actually also a very good way of testing how efficient your filtration circulation is.

    have used this before to great effect, getting the dosing right is a bit hit and miss and if you don't have a powerful pump it makes the algi float to the surface where you can skim it off. much happier being able to see my fish now.

    I only received this product yesterday. I have a small pond so was very careful to use only the correct amount of product which I then added to the pond. This morning one of my previously very healthy goldfish was dead. Coincidence? Perhaps, but I have drained the pond and refilled with fresh water. I won't take a chance and use this again. I feel quite guilty about the demise of this poor fish which was quite happy yesterday and gone today.

    This I would imagine would be an excellent product, Tetra usually is, but sadly I did not read the Write Up on the Product when I bought it and I can not use it on my Indoor Tank which sadly could do with it, but I am afraid to use it indoors, I have read the Instructions, but it definitely says, ​Outdoor Ponds.
    I am going to see if I can find a similar item for Indoor Cold Water Fish Tank. I have always used Tetra Products and found them very good.
