Hello, Our 10 gallon tank is still struggling. We had platies and our Dwarf Gourami was charging at them so my son decided (with my influence) to return the platies. Pretty sure we had females or a mixture and I don't want livebearers. Anyhow, I'm still trying to get a grip on the tank health. I just did the paper dip stick test and pH was 6.0, NO2 at 0.5, NO3 at 20 ppm. I know it's not as accurate as a liquid test so I will be ordering one ASAP. I just did another water change - probably close to 50% because the gravel vacuum wasn't cooperating and kept getting clogged. I added 5ML water conditioner. The water is settling and looking a lot more clear. But, we have a lot of brownish algae growth that keeps coming back. I cleaned it off the glass sides with the magnetic scrubber but it's on the fake plants and the two decor items. What do I do about those? What is that a sign of? We have had to use vacation feeders for the past two weekends and unfortunately we have a 5 day trip ahead of us this week. I can ask a friend to stop by but we don't have someone set to come every day so I have a 7 day vacation feeder I was planning to use. We have one DG and three neon tetras in the tank now plus two moss balls. Also....I think we are leaving the light on too much. Could that be causing the algae? We left the light off for a weekend and the tetras did not look good when we got back. The light seemed to return them to their normal appearance. I'm going to look for a timer to use so it's not on 24/7 for a week. :-/ Help!
