In the last 10 days or so I have developed an extremely bad algae problem : I have to scrape the front of the glass every day.
This may or may not be related to a sudden crop of deaths in my tank. Yesterday I had three fatalities and the previous day had four (tetras, guppies, mollies). The larger fish have survived so far but there seems to be a general drop in appetite.
Last night I checked the pH (this was 6.8 so I added some Correct pH) and nitrate (this was 1.0 so I did a partial water change). I don't have an ammonia test kit at the moment so added some Ammo Lock 2 to be on the safe side. I also reduced the light timer to 8h per day in the hope of cutting back on the algae. I'll get some proprietary algae-destroyer tomorrow. Can algae kill fish like this or is the appearance of algae a side-effect of the condition which is killing my fish.
The only thing which I have done recently is add 5 small tetras from a local store (could the water have been contaminated?)
This is really worrying. I hope that someone out there might be able to advise me before things get worse.
Many thanks in anticipation.
