Eriocaulon and Tonina sp. are the most difficult species of plants I ever had the (un)fortunate opportunity to grow due to my local hard water. Eriocaulon "thailand" - Jake Adams Tonina fluviatilis - Jake Adams I know I've brought this topic up before...but I haven't seen anyone in recent years use these plants. It is a shame! Where did these plants go and where are the aquascapes? -John N.
