NEW Product

Black Pond Dye provides a mirror like reflective surface to your pond or water feature and prevents the growth of unsightly green algae and blanket weed. Black Pond Dye is commonly used by landscape gardeners and uses a safe, economical dye that restricts the light from the sun penetrating the water column, therefore cutting off the light source which causes algae and blanket weed to grow. Black Pond Dye is safe for use with emergent and floating aquatic plants and helps to protect fish from predators such as herons. Harmless to all other forms of life in the pond.

Do:

  • Shake bottle well
  • For best results use in spring before the algae becomes too established or use Magiclear first to clarify the water. For complete control repeated additions should be made monthly as the colour fades. 
  • Mix the correct dose in a clean bucket of pond water, then pour evenly around the pond.

Caution:

  • Undiluted product will stain

FAQs:
Q: How long does Blay Pond Dye last?
 A: The lifetime of the black pond dye is highly variable due to the water conditions, but it should last approximately one month in reasonable conditions.

Q: Does having a uv on shorten the life of Black Pond Dye? A: UV filtration will shorten the lifespan of the dye, as it will break down the pigments over time.

We have been working closely with NT labs for many years now. We stock their Pond range and test kits, we strongly believe they are the best liquid test kits on the market, we use them in-store and have sold many over the years. Last year we have began stocking more of their fantastic ranges including their Pro-f food range and Aquarium range of water treatments.

“I Just wanted to say thank you for the help with bacterial issues I had in my pond. I can happily say that the mouth rot of one fish and the fin rot of two others has cleared up to near perfection now. I have been really impressed with the service from your technical team. I have already recommended online that people ask NT Labs about their products and recommended usage.”

Your Probiotic food is absolutely brilliant! I bought twenty one 1 year old Japanese Koi via a fish farm in Ogata, Japan about 3 years ago. I’ve been feeding them on Probiotic and Probiotic Growth in the summer months. Some of are now 2ft in length and of superior quality. It’s not cheap, but you get what you pay for.

I have used many products for the eradication of aiptasia over the last 15 years. Often with poor results. After purchasing the Anti-Aiptasia, I was astonished with the results! Absolutely fantastic and not like the competitors which normally contains some form of hydroxide. I would highly recommend NT Labs Anti-Aiptasia. This is arguably the best in the market!

I work at a pet store in Durban (South Africa) and have had the best results with my salt water aquariums that I have EVER seen. I have been in the industry for about 10 years now and seriously recommend the products supplied by NT Labs. All our customers that have used anti-aiptasia swear by this product and have said that it over rules every other product out there. Highly recommended.

"I called your offices for support and was put in touch with one of your Aquatic Biologists. He has been incredibly helpful... Without your help, my fish would be suffering and I might have had to stop keeping Koi. I cannot recommend your products, or staff, enough."
