Problems in new tank
#1
I have a new 60l tank 3 weeks old with some itinerant young gold fish. They will go to a pond outside shortly. I have a couple of problems.  I have black filament algae on some of the plants. I was hoping it might decrease with more plants but it seems to be getting worse. I don't particularly want to use an algicide if at all possible. The other problem is that some of the plants seem to be dying, in particular the sassiflora type. At the moment I only have test strips but they indicate that apart from N02 a little high everything is OK. The only test I haven't done is for phosphates which I understand can affect algae. Any suggestions would be gratefully received. Thanks.

Squirting hydrogen peroxide on algae will kill it, but it is completely harmless as it breaks down into water soon after contact with water. How long are your lights on for? Do you use fertilisers? What substrate do you have?

Thanks. I have some peroxide, 3%, but it has phosphoric acid and methylparaben in it. I think a trip to the chemists tomorrow to get some unadulterated would be better. The lighting time I've reduced to about 8 hours. I also have a dimmer and have dimmed the lights during this time too. At the beginning I put one dose of fertilizer in but not since. The substrate is volcanic stone rich in iron topped with course then fine aqarium gravel. The pump is on contiously and the water changed weekly. (20% approx) Do I turn the pump off when using peroxide? I presume so as the flow will dilute it too quickly.

I don't turn the filter off when using H2O2.... Wink
If any nitrite (NO2) is there then you need to do a large water change. It will damage the fish.
I'm presuming you're doing a fish-in cycle with the goldies.......so daily water changes to keep any ammonia and nitrite down as far as possible.
If at first you don't succeed....

Also use a product like Seachem Safe or Prime ( if you can get it in spain ) Or a good water conditioner! I'm sure your aware but make sure its treated tap ( declorinated with water conditioner )

Thanks for the replies. A conditioner was added at the beginning. I bought some proxide today but the only unadulterated I could get is 30%. So if my calculations are correct I need to dilute it in a ratio of 1:5.  I'll pluck up courage and dose the plants tomorrow.. I did another test today with the strips and the NO2 was zero, NO3 about 30 and all the rest were within limits. I'm getting there slowly. When the fish are evicted I'll leave the aquarium empty for a couple of weeks before adding new stock and setting the parameters to suit the fish, whatever they'll be.
I'm still bothered about some of the plants. Some are growing well, others not so. I wonder if there is too much light or algae have taken hold.

You need to add conditioner every time you do a water change.......unless I've misunderstood what you've said......???

Many people misunderstand me, especially my wife  Smile
No I haven't used a conditioner at every water change. I'm going to change today so I'll add some. We are not on mains water here, a tanker comes when needed with water from an underground river. No electricity either, solar panels and a generator.

I'd use it to be on the safe side. A tanker ( being all metal ) can leach something into the water that could be harmful for the fish but not humans, and the water conditioner should bind/remove them. Always use it when adding water to the tank, just to be on the safe side Smile
