AquaDesign Blue Liquid Pond Dye 1000ML For Ponds And Water Features TREATS 40,000L

Does the job.

This really helps keep the water clear. A little goes a long way. Pet friendly too as my dogs think the pond is a huge water bowl! Gives a lovely blue colour to the water.

Does what it says on the bottle

WARNING:There is no secondary seal under the cap. You have to break an outer seal to take the cap off. As I did that, blue dye squirted out over my beige trousers and my sandstone patio. Doh!BEFORE:The water was starting to go murky green. You could only see about 6" into the water but it sparkled nicely over my series of waterfalls.AFTER:My picture was taken reflecting a solid grey sky.The water quickly became a uniform very dark blue; almost navy blue. I much prefer that to the bright blue advert images. It looks quite natural, rather like dark water reflecting a blue sky BUT the water does not sparkle anything like as much. On balance it is better than the previous murky green with sparkles.CLEANING UP:1. The dye came off the patio with a thorough hosing but I gave up on the trousers.2. My wife came to my rescue. She soaked my stained trousers in 'Vanish' but no matter how much 'Vanish' was used and how much rubbing was done, it still looked as if a pen had leaked in my pocket. She soaked the trousers over-night and amazingly, the dye has 99% gone.There's a moral in that story somewhere. I'm sure she'll tell me what it is.

Easier to use nice blue colour pond
