Nutrient Problem???
I've been raising aquatic plants now for almost 1 1/2 years (the first half
was raising algae ), but I'm experiencing some new difficulties. Problem 1. My E. Osiris plant has been growing for great for about 9 months in my 29 gal. tank (takes up half the tank, new leaves are very red and slowly fade to a medium-dark green). Within the last 3-4 days I've noticed a few of the plant leaves (the older leaves on the plant, although I only have 9 huge leaves because the plant is so big) are starting to develop some areas of discoloration. The discoloration is hard to describe (and I don't have a web cam), but here I go... The areas (4-5 separate areas up to 2 inches long covering 3 different leaves) look like the leaves have "dry spots", which is about the best I can describe it. The leaves are all submersed, however, so this is not the case. It's like the top part of the tissue is growing transparent because the underside of the leaves don't show the discoloration. The edges of the leaves are also starting to show the discoloration. The nutrients that I measure are all in good shape (Fe .25 or so, Nitrates 5-10 ppm, PO4 .3 ppm, 4 watts per gallon of light, CO2 around 25 ppm). I know this is a lot of light, but I've been doing this since the beginning and have had no problems for about a year. The tank is also starting to develop Hair algae (slight case). I don't measure for K, but I do dose this once per week after the water change (K2SO4-1/2 tsp., plus the K I get from KH2PO4 and from KNO3). Does anyone have any ideas on this? Problem 2. My snails are dieing again! The only thing I can think of here is the 0.10% of Copper my trace mix contains, or the pH value which is around the 6.8 level. The snails never get really big, always staying pretty young before they die! Any help on these issue would be greatly appreciated! Thank you, -- Craig Brye University of Phoenix Online |

Even when everything else grows like gangbusters, my older sword leaves lose flesh and develop holes. The solution is root tabs-swords are heavy root feeders. I use the Jobs Spikes for Lush Ferns and Palms that are recommended so often on this list. 1 spike per sword plant, broken in half, both halves inserted under the plant once per month. Problem 2.
