Tested my Nitrate levels from tap was around 20. Tank seems to have settled right down now including nitrate levels.(Fingers crossed this continues). Will monitor it and if need be buy what you have suggested.
Thats one thing I have not done. Will try that. If this does show a high reading what is the best way of reducing nitrate. Is it another trip to the pet shop for something to add? or will the filter eventually take care of it?
Yes have read some of the threads. There is so much to try and remember though.
Tank seems to have finished cycling now. Nitrite,Ammonia and PH settled down nicely. Problem now is Nitrate it is getting up to 80-100ppm (think thats right PPM's that is) will this settle down as well. Am changing 20% of water daily at moment to try and get it down a bit. Understand 40 is acceptable.
Yes the picture is the tank we have 'Moby Dick' it is 15" x 8" x 8" and is 20L capacity I have no where near what they have shown in the photo in it though. Just a fake plant,a real plant and a luminous 'awful' bridge thing that the kids wanted for it.
The fish we have are an Orange Oranda (Nemo) and the other one I think is a fantail (Biff) (The kids chose the names by the way).
I cycled it for a week as per the shops instructions. But only added stress zyme and stress coat which came with the tank. (Did not add any food during this). The tank has been up and running for a month now (fish been in 3 weeks) and I have been testing it every day and have changed 20% of the water most days. Now started leaving it for a day or two between changes. Apart from white spot on one of them (treatment sorted this out)fish have been OK.
Both seem like a pair of hungry so and so's, either that or extremely friendly. Been feeding them twice a day (shop said a couple of times a week?) and twice a week have been giving them some Daphnia in a jelly from a sachet(only a drop from it not whole thing).
The filter came as part of a starter kit 'Moby Dick' of all things made by a firm called SICCE. It has two sponges one larger blue one and a smaller white one then a 'bio wheel'. On the whole it works OK the only thing I struggle with is with the nitrite levels.
It clears ammonia no probs. Did have trouble with PH levels but that seems to have settled down now.
I used to keep fish in a tank when I was a youngster and there was none of this measuring various levels of Ammonia,nitrite,nitrate Etc. Now I have a garage like a chemistry lab.
The filter that came with my tank had a small bag of activated carbon which sat on top of one of the sponges in the filter.It had a tag on it saying to remove bag after 3 weeks use. I did this and tank went all cloudy. I bought some stuff to clear it and since then it has been OK.
However nowhere in any instructions, or books can I see if I should replace the bag of carbon?
Should I buy another or will it be OK without it ?
