1 fish dead the other not doing well

[alicia24]

I posted a thread saturday. Added fritz algae clean out a few days ago probably 5 now. Fish were hyperventilating. Did some water changes. Accidently had the sg up to 1.030 with one of the changes. Slowly brought it down now to 1.025. Ph is 7.8 today. Nh3 0, n03 5. Goby died sunday. The puffer has been attached to a rock hyperventilating since this happened but this morning he was attached to the filter. He's breathing slower but still using his gills hard. When he does swim it's at the top and he convulses intermittently. He's not moving his eyes around which is very unusual. I'm assuming he's going to die today. Is it possible he came down with an infection from the stress? I'm really upset about this as this is my favorite fish and I feel very guilty. When the goby died he was shedding skin I'm not sure if that's normal with a fish death he was probably in the tank about 24hrs dead because he was under a rock. Thank you for any replies!

How large is your tank and how much water did you change? Do you have any aeration in the tank? If the rapid breathing began after the algae treatment and not before, you may still need to replace more water quickly and add aeration.

Agreed with above post. High salinity can definitely negatively affect biological processes of fish. If you have a skimmer, run it to aerate the water, if not, drop an air stone in the tank.

Sorry it is 60g. I have done probably 3 water changes over the last 5 days 2 were about 20%, one was 50%. I have put an airstone on and off I get worried that its over oxygenated them as silly as that may sound. I put it back in this morning. I have a powerhead and a hob and just put the airstone back in. I don't have a skimmer. Should I do another water change if so what percent? Thank you both!

You have probably diluted the algaecide adequately with the water changes. Can you provide video and photos taken under white light?

You can't over oxygenate the tank. What are you testing salinity with? I would stop doing water changes and keep the salinity stable. How old is the tank? And have u been testing for ammonia? Sounds like the " algae clean" may have upset your bio filter

the powerhead can be pointed at the water surface, to create surface agitation and help with gas exchange to get oxygen into the water. When lots of algae dies, oxygen levels decrease.

My tank is only about 3-4 months old I know it looks ugly. Thank you for taking the time to look at the videos!!

Thank you! I will do that now

It is a refractometer. The tank is only 3 months old. Yes ammonia had been 0 I tested today. I use api though. Is there anything I should do to restore the bio filter?

and by the way, its very normal for a 3 month old tank to get algae. Part of the maturing process of an aquarium is to go through various stages of algae, we've all been through it, every single one of us. We call it "new tank syndrome", or, "the uglies", it takes several months up to more than a year to get over the uglies. Relying on bottled fixes is the worst thing you can do, as you already found out unfortunately. But there are even worse stories, these anti-algae chemicals can wipe out a tank of corals.

There are thousands of threads on this forum and on the internet on how to fight algae the natural ways without chemicals. it is good reading during the spare time and will benefit you and your tank in the long run.

Thank you. I'm terrified of chemicals now. I just got so frustrated with the algae but I will take a look on natural ways!
