Marms918 Posted March 12, 2022 Share Posted March 12, 2022 (edited) Hi everyone, I am hoping you can help me determine what the issue is with my plants in my 75g. I started the tank in April 2020. Attached is a photo of the healthy tank in September 2021. I noticed the anubias leaves curling/darkening in December and this is what they look like as of yesterday. Every anubias in the tank has this issue. My amazon sword and banana plant are also looking bad, so I wasn't sure if it was nutrient related. Is this some form of algae? I've searched online and can't find a picture similar to this. Nothing rubs off when I touch the leaves. There is some black algae in the sand/front of the glass. The tank is cloudy in the pic because of a recent filter clean, normally the water is clear. I did change some rocks in September - could this have contributed to the problems with the leaves? I have another 20g long that has been running since Sept 2020 with the same rocks that is mostly thriving, including the snails doing better, so I am not sure what is different from each tank. I moved a sword from the 75 to the 20g in Sept 21, and you can see the growth. Stocking: 2 EBAs, 10 congo tetras, 1 SAE, 2 mystery snails, 1 BN pleco, 7 corydora (had 6 and they bred at some point - noticed the extra cory after it was a few months old) The EBAs have also bred several times. The last successful batch was in September as well. Parameters in 75g: ph -7 am-0, ni-0 na-20-40, FX4 filter + large 40+ sponge filter. Fluval 3.0 I do a water change of 50% every 2 weeks. My water is soft- kh-0-1, gh- 3 and I did have issues with the tank dropping to <6 ph in the past but I have put crushed coral in the filter and that has stabilized the ph. I have dosed Easy Green, but not with any regularity because my nitrates are always higher. I used to have water sprite that was exploding, but over time it slowly died as well. I want to start over, but should I just cut all of the leaves off of the anubias? Java fern, jungle val and crypts have never done well in any of my tanks if that helps. Any thoughts are appreciated! Edited March 12, 2022 by Marms918 added fluval settings - been this way since April 2020. Link to comment Share on other sites More sharing options...
