NeRo9k Posted April 3 Share Posted April 3 Hey Everyone, I've had a Top Fin 55 gallon going about 3 years now but I recently (thanksgiving) moved the tank to a different part of my house. I changed the substrate out and rearranged the wood, stone and plants for the most part. Everything with the tank is going well, I lost no fish and all of the stem plants (only a few) seem to be doing few. The issue is my larger Anubias plants are all suffering from the same issue. The tips and the sides of the plant starting from the top towards the stem go dark which gradually moves towards the middle of the plant leave causing small holes to develop until it eventually takes over the entire plant causing it to turn dark black and then yellow. This is a pretty slow moving process and new stems/leaves seem to grow very healthy and in good color until slowly, over time, they develop the same issue. The pictures will show different stages of development of this disease/deficiencies and I let some get really bad just for the sake of being able to take pictures to show the evolution of this plant 'issue'. I suspect this is stemming from a couple different deficiencies rather than just one but I would love any advice that you could provide to hopefully stop this 'issue' from getting worse. These large plants took many years to grow in so clipping the stems is always painful. I have hard water with a very high KH and a PH of about 8-8.2. The standard LED lights that came with the tank runs 8 hours a day. I do water changes about every 2-3 weeks as I have a fairly high stocking level which leads to a nitrate level of about 60-80PPM before a 50% water change takes place. I historically haven't dosed the tank as Easy Green brings in more nitrates that I don't need. Every so often I'll buy 'generic' fertilizer that doesn't contain nitrates. In the past I've dosed Seachem Potassium weekly but I haven't recently. I've also used Seachem Phosphate sparingly when I thought maybe part of the darkening was caused by low phosphate levels. I have a 75 gallon that has been running starting from Thanksgiving with similar plants and the led strip that came with the tank (9 hours a day) - On that tank I do dose Easy Green. Overall most of those plants look healthy in that tank but I seem some leaves have a similar problem as the plants in the 55 so I suspect it's the same issue just not as bad; but I don't want it to get worse obviously. 1 Link to comment Share on other sites More sharing options...
