Now it has become worst. The water has also turned brown.

My diatom bloom quite serious. Am wondering phosbuster will help?

Pinkish on rock over rule by diatoms already..

Thank you for your advise. Waterperson

Thank you waterperson, any idea why my ammonia increase slightly? I used 144litres of distilled water to change. I did not add anti chorine so I shouldn't expect ammonia to show up again right.

Did a water change, reading nitrate 0, nitrite 0 and ammonia slightly off yellow but still not on the 0.25ppm. I think it is in between 0-0.25. I am still puzzled that nitrate can drop from 40 to 0. I am not not sure if my cycling has completed or I have mess it up some how

No water change yet. Only top up water after evaporation. 27days cycling.

The weird thing is my nitrate becomes zero also.

I am done cycling right?

And also I realise that there are signs of diatoms already. Can I start the phosphate reactor now during cycling?

Actually I did also wonder about this issue if the media I place in there is enough also. Looking at my sump, my media are all fully submere in the water which is already not like wet/dry sump type. But I realise alot of people kept their sump so simple until it's like no where to house bacteria and that is why I suspose the rocks in the tank are. Can advise me if I setup mine wrongly?

I actually have some coral chips and this bio dog shit inside also. But actually I am thinking actually the rocks in our tank already able to hold quite an amount of bacterial already right?

Thanks. I just did a test. My ammonia is still stuck at 0.50ppm but my nitrite and nitrate went up again. I think it's because my ammonia kept being consume by bacteria to form nitrite . And that's is why ammonia not climbing further despite adding 4 dead prawn 2 days ago

Ok after realise my very initial introduce of ammonia was not enough, I added 4 more minced market prawn today. And I start to have readings for my nitrite and nitrate. But still my ammonia level still remains the same at 0.25 to 0.5. So I actually think that my initial cycling wasn't a total waste of time as I actually have existing bacteria to consume the ammonia to form nitrite. It's jus that the amount was insuffient thus I did not have an amount of nitrite to be able to be read from testing. Am I right?

Sembawang shopping center. If u r there u can also try giant. They have similar fan of diff size. I think the brand is powerpac

Yup. I tot of that as well. I am thinking of totally remove the front and back grills to just expose the fan blade. But got to be careful when doing maintenance

U might want to try Sona clip on fan. I got it from ntuc for $24.

Just tested again.

Ok thanks a lot. But looking at the saltwater chart, I am confuse if mine is 0ppm or 0.50ppm

Arh.. Then my ammonia also zero after 3 weeks of cycling.

Oh lol. Thanks

And also another question, why is it that I have only ammonia till now in my 3 weeks of cycling. I threw in a prawn on the first day to introduce ammonia and till now still the same. Could it be insufficient? I also started dosing microbacter7 4 days ago and yet to see any nitrite

Hi, my new 422 fowlr setup is currently undergoing cycling. And it's about 3 weeks old only. On the 2nd week of my cycling phrase I actually purchase afew piece of cured live rock and hope that it will seed my dead rocks with coroline algae faster. Until yesterday I realise some light pink patches starts to appear on some rocks. Can you guys advise me what are those? Really hope that it's coroline algae also lol.. Tank age 3 weeks Tank size 422 with 3 ft sump Skimmer and FR is off Filtration- socks and some ceramic rings Return pump at 6000 litres/hr with 1 wave maker

Go YouTube and do a search. Quite a lot of video abt ATO. There is also a lot people diy

Ya I am running a fan, I think that's the reason for fast evaporation. Oh.. I tot that 3L is not normal. I really need to get an ATO to save all the hassle. You guys tried the ATO from gemsurfs? The newer one with infra ray sensor I think.
