Scaperoot Posted February 18 Share Posted February 18 Can anyone identify this substance on these plants and decoration? This is my FIL’s tank. He just started adding real plants in November. Nitrates are high (pic posted). He’s not overfeeding from what I can tell. Link to comment Share on other sites More sharing options...
CJs Aquatics Posted February 18 Share Posted February 18 Hard to tell from pic, 1st picture looks like uneaten food that is rotting to me, it could be algae as well though, second pic looks like the start of a form of hair or BBA those are my best guesses 1 Link to comment Share on other sites More sharing options...
Guppysnail Posted February 18 Share Posted February 18 Mostly I see mulm and debris. Increasing the flow and making sure it’s even as well as decreasing feeding amounts should rectify both the substance and decrease nitrates. 1 Link to comment Share on other sites More sharing options...
Scaperoot Posted February 18 Author Share Posted February 18 It turns out that my FIL had not done a water change in 2 months. Aside from that, does he need to physically remove this from plants and decorations? Should we consider using Excel? Link to comment Share on other sites More sharing options...

Can you have them run a test on the tap water so we can double check the tank parameters. Your GH and KH results are pretty high off the chart.

I wondered, seeing the KH and PH on the strip. What does his tap test? If it's a lot different, he should probably do a few smaller water changes over the course of a few days to a week rather than one big change, so it doesn't change PH too rapidly. 1 Link to comment Share on other sites More sharing options...
nabokovfan87 Posted February 18 Share Posted February 18 This could be explaining what's going on. Especially the second part of this video.

I would just pull and rinse what you he can and let the tank take care of the rest. Tell him not to go hog wild with large water changes right away. Start small and work his way up will be more gentle on the inhabitants Link to comment Share on other sites More sharing options...
PineSong Posted February 19 Share Posted February 19 What kind of fish are in the tank? I ask because that messy stuff looks like the kind of cleanup job that mollies specialize in, and platies handle pretty well, too. If his fish are compatible with any of the above, you could add a couple or male mollies or platies (male to eliminate risk of babies) and let them take care of it--after doing some water changes.

Scaperoot Posted February 19 Author Share Posted February 19 This is how his tap tested. By the time I read the recent replies, he had done a 50% water change. This is how the tank is testing now. Link to comment Share on other sites More sharing options...
