Linda4fish Posted February 19, 2022 Share Posted February 19, 2022 I planted this by Bacopa Carolina about a month ago and it’s thriving but as it gets about 2/3 of the way up into the tank it’s looking bleached at the leaves i would not say yellow… The tank light is on eight or nine hours a day broken into two seperate episodes one 3 hours and one 5 hours NICREW full spectrum planted tank LED 20 watts on a 29 gallon tank Link to comment Share on other sites More sharing options...
JoeQ Posted February 20, 2022 Share Posted February 20, 2022 Im no expert on this but I wanted to give a thought. Maybe too much light is the problem? Maybe nutrient deficiency? What are you dosing, any extra iron? How bout water parameters? Link to comment Share on other sites More sharing options...
Linda4fish Posted February 20, 2022 Author Share Posted February 20, 2022 Im using root tabs on other plants and dose occasionally with easy green but tend to bet black beard and hair algae🤢 As I understand it I need to do more water changes if I’m going to use fertilizers. i have hard water and ph is 7.5+/- im thinking too much light the stems are turning a bit bronze as well Not really the look im after I love the way the plant looks otherwise I’m thinking of getting some more and putting in an area that’s a little more shaded Link to comment Share on other sites More sharing options...
JoeQ Posted February 20, 2022 Share Posted February 20, 2022 These look good to me, Carolina develop red at the tips with higher amounts of iron, and you shouldn't need to buy more. Just lop the tops off and replant the trimmings! Both stems will regrow! Here is a picture of mine before I clear cut my tank. Also fyi, I planted in shaded areas and they definitely like the bright spots the best! If you look closely youll see my pesky hair algea problem.... 1 Link to comment Share on other sites More sharing options...

What root tabs are you using and are you dosing per the instructions? When was the last time you added some. You indicated your pH is about 7.5 do you know any other water parameters like dKH, dGH, or nitrates? How "occasionally" are you doing Easy Green? Are you dosing per the instructions? -Roy Edited February 20, 2022 by Seattle_Aquarist Link to comment Share on other sites More sharing options...

Possibly you have a well stocked tank and they are generating nitrates as well. When I first saw your photo I figured it was either insufficient available nitrogen or insufficient available iron which are the most common causes of chlorosis (yellowing) of new growth. Other than the small squirt once a week on the Easy Green keep using the tabs as you have been but how about putting one tab under the Bacopa as well. Lastly, because the iron in Easy Green is basically unavailable with a pH of 7.5 I want you to start dosing Seachem Iron which is made from ferrous gluconate and is more easily absorbed by plants when the pH is above 6.8. Dose 1/2 capful 2X per week. If we are on the right path you should see improvement in new leaves after 2-3 weeks. DO NOT WATCH EXISTING LEAVES, THEY WILL NOT CHANGE SIGNIFICANTLY. Watch the new leaves as they emerge, they should show a healthy green color if iron is the reason for the chlorosis of your new growth. Please keep us posted as things progress, -Roy 2 1 Link to comment Share on other sites More sharing options...
Torrey Posted February 21, 2022 Share Posted February 21, 2022 Roy, thank you for explaining the differences in iron, and bioavailability changing based on pH. My plants thank you, too. @Linda4fish, thank you, too! 2 Link to comment Share on other sites More sharing options...
