Hi everyone. I don't seem to be having much luck at the moment. It turns out that the filter I have been running for 2 months which helped me cycle my tank is on its last legs. Every now and again the water flow drops down to pretty much nothing. After taking it apart it seems to then spring...

Thanks everyone. I'll keep an eye on it.

Thank you. What percentage water changes would you do if I do need o change the water?

I cycled using pure ammonia and monitored the levels everyday. The tank was fully cycled before I put fish in.

I carried out the last water change 3/4 days ago. The tank has been set up for 2 months now. I added fish about 3 weeks ago. My concern is that I go away on Monday and the fish won't cope.

Apologies - I mean nitrite

I realised this evening that the power to my aquarium had been off for 4 hours due to a problem with the extension lead I am using.   It is all running fine now but after testing I realised that the ammonia and nitrate were at 0.50ppm. My 5 tetra seem fine and aren't gasping for air etc... I...

Wow. Thanks everybody for your help, it's much appreciated. My only issue is I can't measure the PH very accurately using the Api Master Test Kit as the low range test shows an off the chart dark blue and the high range test shows a reddy brown colour which is also not on the chart. Had anyone...

Thank you. Should I just leave it as is (i.e is this tap water ammonia safe for the fish?) Would you recommend using bottled water instead on the next water change? Thanks again.

Hi. I don't know what step to take next. I upgraded my tank on the weekend using the same media from the old tank. There now seems to be a slight amount of ammonia (the API test kit shows a slight hint of green which is difficult to see in some lights.) I tested the tap water last night and...

Thank you. Is it ok to add more gravel as the current tank doesn't have enough?

Hi, my tank is fully cycled and I currently have 3 neon tetra in a 20l tank. I would like to get a larger tank but I am unsure how I would transfer the fish etc.. Would it be ok to transfer everything including the filter from one tank to the other and then add the fish when the temperature is...

Thanks for your help. I cycled the tank using pure ammonia. The levels seem pretty stable, ammonia is 0 and nitrite is 0. Nitrate is around 30 - What is the maximum level I should let the nitrate climb to? I am hopefully going to get a guppy on the weekend and maybe another tetra to join the...

I do have plants. Maybe that's the reason. The PH still confuses me though. I can't work out the reading. It's dark blue on the low range and a browny red colour on the high range. Thanks again

The tank is 20l, it was cycled using pure ammonia and the levels are currently as follows: Ammonia: 0 Nitrite: 0 Nitrate: 30 PH: I have the API Master test kit. Using the low range kit the colour is dark blue. Using the high range it shows a brown red colour which isn't on the chart? The...

Last week my tank was fully cycled so I stocked it with 3 neon tetra and 2 shrimp to start off. This weekend the shrimp died after behaving strangely and rolling onto their backs etc.. The tetra seem happy apart from the fact that they seem to always be chasing one another. I have an API test...

Thanks for that. I was in my local fish shop today and was talking to them about the cycle. They told me that I should now stop feeding the tank ammonia until I see nitrate, is this true? I have also heard that you should reduce the dose of pure ammonia at this stage. What is normal...

Nice answer, thanks for your help. The PH is at 7.4 at the moment. What is the ideal range and how do I adjust this if it changes? Even though the nitrite is off the chart will it drop to 0 when there is enough nitrate? How long do you reckon this takes in a 20l tank? Thanks again.

Hi all, The good news is my tank is already on the way to being ready for fish. Yesterday I added ammonia to take the levels up to 4ppm and it was back at 0ppm this morning. My first question is how long can the bacteria live without food? Obviously I will be testing every day and adding more...

Hi all, I am wondering whether anyone has used the All Pond Solutions 30CM SUBMERSIBLE 34 X LED AQUARIUM FISH TANK LIGHT in their aquarium...

Do you have any recommendations on LED/Replacement light units for my tank please? Thanks
