Time will tell how well they work. They are not easy to place in a gravel substrate.
Plants seem to love the root tabs.
Root tabs have been working great so far!
It is really to soon for a review of the efficiency of the product since I just received the tabs
Haven't yet needed to open the pkg
But I can say WOW to the fastest delivery in the west
And as for packaging - the tabs arrived safe and sound
Thanks Aquarium Co-Op Team
Very good my plants do very good with the root tabs
