Flourite Dark™ is a specially fracted, stable porous clay gravel for the natural planted aquarium. Its appearance is best suited to planted aquaria, but may be used in any aquarium environment. Flourite Dark™ is most effective when used alone as an integral substrate bed, but it may be mixed with other gravels. Gravel modifiers such as laterite are not necessary. Flourite Dark™ is not chemically coated or treated and will not alter the pH of the water.

Although pre-washed, it may be rinsed before use to remove residual dust. Dust can also be minimized by filling aquarium slowly and dispersing water so that the Flourite Dark® bed is not disturbed. Slight initial cloudiness is normal and will clear rapidly (2–12 hours). To shorten the cloudiness period use Clarity™ in conjunction with mechanical filtration (such as filter floss).

FAQ (Frequently Asked Questions)

Yes, you can order fish along with dry goods. However, if the dry goods are heavy or bulky, it may be more cost-effective to place two separate orders. In that case, you could ship the dry goods using a slower, more affordable shipping option.

If your order has not shipped yet, you can email us your correct shipping address, and we will update it for you.

On weekdays, if we receive your order before 2 p.m., it will be shipped out the same day. Dry goods are shipped from Monday to Friday. Orders that include livestock are only shipped from Monday to Thursday to avoid transit over the weekend.

At checkout, you can leave your request in the comments box.

Our locker boxes are located in the foyer of our store at 230 Hanlon Creek Blvd, Unit 107, Guelph. The room is accessible from 9 a.m. to 9 p.m.
