Controlling Thread Algae with Pond Block
Pond Block consists of a biological binder that dissolves very gradually in your pond. When the algae come into contact with the released substance, they will die and sink to the bottom. As a result, the water will become clear again. Complete dissolution of your Pond Block takes several months, allowing the active ingredients to enter your pond water slowly and dosed. Evaporation of your pond water and/or rainfall does not reduce the effect of the Pond Block. Since algae grows throughout the year, the Pond Block can also be used in winter. For cleaning up the dead algae on the bottom, it is best to use Bacta Clear(pond bacteria).

When will I receive my order?
The average delivery time is 1 to 2 business days, if items are immediately in stock. Items not in stock take a little longer to arrive. We make every effort to meet the promised delivery time. If this unexpectedly fails, we will notify you. After your order you will receive a track & trace code. Keep an eye on it for the most current information.
By whom is delivery performed?
We work together with the delivery service DHL. As soon as your order leaves our door, you will receive a track & trace code with which you can track your package. DHL makes an attempt to deliver the package on the indicated shipping date. Are you not at home? Then the deliverer will try to deliver the package to the neighbors. If this also fails, the package will be taken to the nearest DHL service point. Here it remains for you to pick up for 5 days. DHL always leaves a bill with instructions. Also via the track & trace code you can see where your package can be picked up.
How can I track my order?
After placing your order, you will receive a track & trace code (DHL). Through this code you will find the most current status of your order.
How can I pay?
Whichever payment method you choose, you will always pay securely.
- iDEAL: for anyone with a Dutch bank card.
- Credit card: the amount is reserved and not debited until the item is delivered.
- PayPal: secure online payment through your own PayPal account.
- Bancontact / Mister Cash: online payment method via your own internet banking environment.

Where do I find my invoice?
After your order, you will receive an invoice via email.
We also store your invoice online in your account. So you can easily access and print your invoices as often as you like.
Will I receive an invoice with my order?
No, we never send an invoice with the order itself. Therefore, if the order is a gift, feel free to send it directly to the recipient. The invoice will be sent to the e-mail address known to us.
Do I have a warranty on my plants?
Our plants are grown with the utmost care. Special attention is paid to the development and growth of the plant. When packing your order, quality control also takes place. So you can be sure that the plants you purchase from us are core healthy.
Did you receive plants and you are not sure about the quality? Please let us know within 48h after delivery, using this form. Enclose a photo so that we can look at the plants with you and advise you. If it turns out that the plants really are not of good quality, we will of course guarantee your purchase.
All other (non-living) items you buy from us are covered by the legal warranty. Legal warranty means that a product is or should do what the consumer can reasonably expect it to do. A manufacturer's warranty also applies to some products.
How long is the warranty valid?
If you are found to be entitled to the grow and bloom warranty, it is valid for 1 year from the date of purchase.
What is my warranty certificate?
Your invoice or proof of purchase is also your warranty certificate. You can keep your invoice in your account. That way you will never lose it again. Handy, right?

Swamp full of aquatic plants
Thanks to Simon Van der Velde I have a nice clean swamp full of water plants again! (Finally free of annoying algae...) Clear advice, fast delivery, and : a passionate honest nature loving grower with one goal : to find the best solution !
My pond is a small world full of biodiversity.
I bought a water lily, oxygen plants and some more aquatic greenery for my mini toad pool in a specimen tub. The water stays beautifully clear and the aquatic plants grow like cabbage. Sometimes damselflies dance above the tiny lilies. A climate-proof mini-oasis for our dry summers!
Very good service
Over the years had poor quality plants that break down every year. Until I came to this company. Good advice from Simon, he just tells you exactly what you need and what does and doesn't work. Very personal good service and someone who takes the time for you. Read More
Great selection of plants with extensive information. Order was delivered promptly and arrived neatly packaged in a sturdy box. Plants and accessories were in separate, matching packages so everything was in great condition, there was nothing mixed up. Read More
Super fast delivery. The price-quality is really quite good. A complete package with a clear description. This simply cannot fail. Already within a few days the first leaves of the water lily were visible on the water surface. Here I order so again!!!
Excellent supplier for healthy pond: fast, knowledgeable, well packaged.
Made several orders a few times. Communication is great, they respond super fast and knowledgeable. Ordered moss balls a few times so far, crabber and stuff for algae control. Read more
