Ok my tank is a 55 gallon, with canister filter and lighted by 2 T5 lights, each 52 W. I only use 1 light, bringing the lighting to just under 1 wpg. It is stocked with 5 zebra danio 6 harlequin rasboras 2 neon tetras 2 otos I am injecting about 2 bps of CO2 into the aquarium. It turns on...

Hi guys, For the past 2 weeks, my tank was taken over by BBA. I tried to clean it up by spraying Excel directly onto the java fern leaves but only managed to burn the leaves and turned them brown. I cut off the dead leaves, leaving only the rhizome but still the algae took over. So I removed...

By the way, the temperature of my tank is around 28 - 29 degrees celsius. Hope someone can chime in and share the same experience and what they did.

Hi guys. My tank has been running for about 3 months now. It is stocked with 5 zebra danios 6 harlequin rasboras 4 neon tetras 2 otos About a month ago, I thought that my tank had an attack of diatoms as the glass was covered by rust coloured algae but I managed to clear them by using an...

Hi, please do not give up! I also did a fishless cycle and I took 6 months, yes! 6 months to cycle! I had a whole host of problems, pH crashes, total BB die off, soft water, the whole works. Now after the experience, I know what to do, also with the help of helpful people like librarygirl and...

Hi guys, just wanted to let you know that my tank has cycled and stocked. Thank you for all your help and advice, especially to Eco and librarygirl =) Here is a photo as required =)

Btw, I am a teacher so I get my ammonia source ftom my school chemistry lab. It is very dilute though so I do need to add quite an amount to reach 4ppm.

Hi librarygirl, the nitrates is from the conversion of nitrites. Could it be from lack of oxygen? I do have a bubble wand in my tank running though. For water changes during cycling, do I do a 50% WC or 90% WC.

According to other aquarists in Singapore, they have tested the water and ammonia is present in the water at about 0.25 ppm.

Hi guys, It has been 5 months since I have started fishless cycling and to me it has just been a thankless chore, it is still not done! After 5 months! One of the issues is that I have very soft water coming from Singapore, from the tap it is 7.0 but after a few days it will drop to 6.6. I...

Hi there librarygirl, an update here. I did a 90% WC before I seeked the advice of the guys here. Now, instead of processing 1.75ppm of ammonia a day, it has dropped to 1ppm per day. It seems that everytime I do a WC, it slows down the cycling process. But sometimes I am forced into it as my pH...

Hi there again! I have taken librarygirl's advice and have been dosing ammonia to 2ppm. Even then after 24 hrs, there was 0.25ppm of ammonia still present in the tank. So I did a 90% WC yesterday and vacuumed brown stuff off the top of the gravel as I saw too many nematodes and planaria around...

During the nitrite spike and when it was coming down, the ammonia only dropped to mostly 0.5ppm - 1ppm. I have never seen it go to zero. Dont really know why. I will try your suggestiion librarygirl, thanks for the advice. Although I will be going away for about a week or so in 2 days time. Will...

Yup, it drops from 3 -4 ppm to 1ppm in 24 hrs. Nitrites were evident, from more than 5ppm to clear baby blue now. Just that the ammonia is not dropping to zero at all, even after 90% water changes and dosing up again. pH is always at 6.8 last I checked, even after 90% WC.

Hi there, its me again. And yes, my tank is till not cycled, 3 MONTHS since I started! Don't know what is wrong but the NH3 just does not seem to go down to zero after dosing to 3ppm - 4 ppm. After dosing to 4ppm, after 24 hrs it'll go to 1ppm then another 24 hours later, without dosing it'll...

Ok I have checkrd my levels for today after adding in the bubble wand. pH : 7.6, up from 7.2 nitrite: 0 same as yesterday's Ammonia: 1ppm from 3ppm yesterday. So conversion is still happening but at a very slow pace. Seems like the BB has been stunned and is just waking up from a daze...

Its not brown on the surface but after using the paper towels, brown sludge is found on the towels. Yup the increased agitation removed it. Hopefully it'll help to show some positive results.

Yup there is always this layer on the surface of my tank water. I use paper towels laid on the surface to remove it. The filter outlet is on one end of my tank. Since my tank is 4 feet long, the other end does not get disturbed much and will form this stagnant layer. I read that this protein...

Nope, i put in Prime while the water was filling up, enough for the whole tank. I just put in a bubble wand just now, maybe there was not enough oxygen in the tank as the water surface keeps being covered by this brown layer so I cleared the layer and agitated the surface with a bubble wand...

Hi guys. On Saturday, I did a 90% pwc as my ammonia didn't seem to be going down increasing from 0.25 to 0.5 to 1ppm. Now after the pwc it's even worse! Seems that after 24 hrs there's hardly any conversion at all! Its at 3ppm after dosing 4ppm fron the day before. What is happening? Nitrites is...

Ok eco, I will do the pwc tomoro. Any recommendation on hoe much to change? 75% or 90%?

Ok I have dosed to 3ppm of ammonia tonight. Will see if the dosage will drop to the lower levels after 24 hrs.

Hi guys, just checked my levels today. pH is 6.8, nitrites is 0.25 and ammonia is 1ppm. My ammonia levels have been increasing for 3 days in a row, after dosing to 4ppm. The day before it was 0.25, then yesterday was 0.5 and today is 1ppm. Is there something whacky going on? I only have plants...

Thanks eco! From the tap, after leaving the water un a cup for 24 hrs, the pH is 7.2. In my tank now, its about 6.8. Will this difference be an issue when I am making water changes, especially when it is stocked?

I have the same situation as Rhino. My ammonia drops from 4ppm to 0.25 or 0.5 in 24 hrs and my nitrites are now from 5ppm to 0.5ppm. My pH has remained stable at 6.8 (pale blue) for almost a week since i fashioned a home-made holder for the coral that I placed in front of my filter outlet...
