Dying Fish

[This Old Spouse]

Just about to ask about nitrate reduction, then saw your signature line! My nitrate level always hovers around 40, and my tank has developed some black bearded algae, so I'll try a larger water change and see what happens.

Beard algae is one of the worse algae to get rid of. I dont think water changes will get rid of it. Beard algae is introduced to the tank via plants or fish and does not just develope. If you have this on plants then remove the infected leaves. If on any decor then remove and sock in a bleach solution. I struggled with this and ended up stripping the tank and sterilising everything.

On the topic of nitrate and the level in question 40ppm, IMO this is not a dangerous level and would think no reason for concern. High nitrate levels where the tanks water chemistry has poor buffer capabilities(gH/kH) can present pH problems for the fishkeeper. My Tap water nitrate level comes out at 10ppm whilst the aquariums nitrates are 30-40ppm at water change(20-30ppm difference), for me this gives me valuble info as to how things area)Its under control(B)My pH is going to be ok(C)its going to help keep algea levels down.

quick update..
unfortunately when i woke in the morning my gourami had died. on inspecting the fish afterwards apart from a unhealthy looking fins ( same as in picture.) there was no other problems. no discoloration to body etc. i did clean filter do large water change etc. and now have a reading of 20 for nitrates. i decided to buy some fin-rot treatment just in case for future. is there any way any other fish may be/become effected? i have also moved my silver dollar into my dads tank with his other two larger ones and she seems to be doing fine. thank you for all the help so far.

Well done with the nitrates, regardless of the varied opinions I'm sure everyone agrees the lower the better. Fin rot is not contagious so don't worry about your other fish becoming infected. Keep up with maintenance and you'll be fine

I am one of those whose tap water has 40ppm nitrates and I was advised to keep it as low as possible. I am going to add some plants to try to lower it a little, but I don't panic, at least after advice from here
