OMG So long I haven't posted.

Well,
gH is 2
pH is 7.2
Ammonia is 0
Nitrite is 0
Nitrate is 10

The water has been stable and I had no more fish deaths. Opposite I had a gravid Platy.

The last Guppies tail is regrowing now and he is holding on. I have however got a problem with algae and was considering taking the Oto into the bigger tank and getting a new mate for the Fighter, but that's uncertain yet.

Thanks for all the help

Hehe good news then Sofia, sounds like your tank is settling down nicely. Shame you had all the problems at the beginning but at least you're on top of everything now /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

What colour is the algae Sofia? Brown, light green, dark and slimey?

Dunc´s asking this as different kinds of algae might only be eaten by certain fish species Sofia. /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> Also Otocinclus should ideally be kept in a group as they´re sociable wee things so maybe add a few more of those too?

Brilliant /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />
The Oto's friend died very early on and I was scared to get new fish, because there were so many deaths, as you know.

Algae is light green, very patchy and appears on the gravel, but mainly the glass /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

Urgghh that stuff on the front glass is a pain, really needs to be scrubbed /ohmy.gif" style="vertical-align:middle" emoid=":o" border="0" alt="ohmy.gif" /> Not sure which fishes will touch that, I'm sure one of the gents on here can enlighten us.

Otos are small little things so you can keep 6 to 10 fairly easily, even in small tanks.

Oh, brilliant. I shall convince the other half to take me fish shopping this weekend then /ohmy.gif" style="vertical-align:middle" emoid=":o" border="0" alt="ohmy.gif" />

Do you think it's save to add fish to the main tank? It looks a bit empty /sad.gif" style="vertical-align:middle" emoid=":(" border="0" alt="sad.gif" />

EDIT: I have scrubbed it with the plastic rough scrubby thin I got, but it won't budge /angry.gif" style="vertical-align:middle" emoid=":angry:" border="0" alt="angry.gif" />

how old are your light tubes? Should be replaced approx every 12 months really. Do you have high phosphates as this could also be causing the problem.

It´s a new tank Richy so shouldn´t be the lights. Could be Phosphates though as I know some parts of London have high levels in the tapwater....

The whole tank is now only just over 3 months old and so are the tubes. i don't know about phosphates. How can I find out?

I have:
5x Harlequin
5x Croaking/Sparkling Gouramis
4x Platies
1x Guppy
1x Neon
1x Ram

EDIT: I use ro water that I add RO Right to to make it suitable for Bettas, etc.

if you have a look here it will help you find exactly what kind it is /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />
ALGAE

EDIT* some lfs's might be able to test for phosphates but most marine centres should have a kit to test for you. I have a salifert one but D-D phos kits are the best.

Green Dust Algae I think is what I am after. Seems to be easily fixed...if i knew how to increase the CO2 in my tank and add nutrients...

Description Forms on the glass creating a dusty appearance across the glass. Sometimes so bad you can't see into the tank.

Cause Low CO2. Low nutrients. Quite common on new setups.

Removal Easily removed with a magnetic glass scraper or similar. Often reappears very quickly. Allow the algae to run its full cycle by leaving it well alone for 3 weeks. It may become unsightly but just bear with it. Then scrape it all off and do a large water change. Sometimes requires a second treatment to fully clear and leaving it for 4 weeks. Recommended to slightly reduce dosing during treatment.

Thanks Richy

it will burn itself out as the tank matures so just keep cleaning the glass. High nitrates and phos will feed it along with strong lighting. You could cut the hours of lighting down a bit if you wish but if you have live plants then about 8 hours. My lights are on for 10 hours but i dont have algae /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

I do have live plants and my tank light is on on average 8-9 hours a day. I had the problem once before and then it settled and now it's back. I guess I'll just wait /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

Thanks

If everything seems to have stabilised I see no reason why you can´t add more fish now Sofia. Remember the problems you had earlier on and don´t add too many at once though. Some more neons OR guppies OR Otocinclus would be alright, but not all the same time. /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> If the algae is that green spot stuff Otos won´t eat it though. I can only ever get that stuff off with a razorblade or one of those scrubbers for acrylic tanks....an algae magnet won´t shift it either. /rolleyes.gif" style="vertical-align:middle" emoid=":rolleyes:" border="0" alt="rolleyes.gif" /> Oh and we can discount Phosphates as although they do affect the growth of this kind of algae they only do so at very low levels. Just to confirm dear, is this what you have?

Ok I´m confused. Sofia you say the algae is very difficult to remove but that green dust stuff is easy to clear. In my last post I´m referring to green spot algae, these two are very different types so-o....which do you have? /tongue.gif" style="vertical-align:middle" emoid=":p" border="0" alt="tongue.gif" /> Here is green dust algae (GDA), my pic above is green spot algae (GSA):
