Updating this thread with a heavy heart. This tank was hit with severe RTN and I lost most of my coral. Water was very milky and had a smell of liver. For some reason my acropora, millepora and encrusting monti was not affected by this.
I fragged all sps that appeared unaffected by this...
At this point I have no clue what to NO3 is sitting at. However, I suspect it can not be very high due to the water changes - I have changed a 240 liters over the course of a month. I will test all parameters this Saturday.
@ Quintonv thanks. I am very excited for this setup.
Tested water today:
Seems like the tank is finally cycled.
Now to leave the tank for a month for the bacterial film to build up.
For those interested, I ended up finding some guidance for Dr Tim's one and only. The instructions stated that NO2 of 5 ppm or more significantly increases the cycle time. The correction for this is to perform water changes until the NO2 is below 5 ppm.
I was reading up on high nitrites during a cycle. I could only find reference to Dr Tim's one and only. It stated if nitrites exceeds 5ppm, water changes should be performed. It stated at that level the bacteria can not function and it will increase the cycle time significantly...
I started my tank on 4 Jan 2019. I have the following biological media in the tank for bacteria:
Maxspect nano tech blocks (since 4 Jan)
29 kg of dead man made rock (since start of Feb)
6.8 kg caribsea special grade substrate (dead) (added 22 March 2019)
500 ml seachem matrix (added 6...
Cycle and filtration update
Tested water yesterday:
Nitrite 5 ppm
I am baffled by the no2 readings.
Added 500ml of Seachem Matrix to the sump and got special blend and nite-out II. I have turned off the skimmer and will run the tank without the skimmer for 2 weeks.
Results of tests performed today
Nitrite: 5+ ppm an improvement (hue was lighter) previous test , but still high
Will be performing a 40 litre water change.
Any advice on finishing the cycle will be appreciated - tank has been cycling for 3 months now...
Equipment, cycle and filtration update
The following items were picked up this morning:
1 Odyssea T5 unit
Not sure how good the bulbs in the T5 unit are, but will get some ATI bulbs later on.
Picked up a 100 litres pre-mixed salt water to do the + 50% water change.
Used some epoxy and super glue to secure the base rocks. Will do the middle layer of rocks tomorrow and the top one on Sunday.
After a thorough rinse, the sand has been added :m01:
Ok, maybe not the best rinse ever. Will let the skimmer and filter sock deal with it.
Will this work as a reservoir
I am looking for something that can hold about 50 liters.
Any recommendations and feedback will be appreciated.
Thanks in advance.
Cycle, fish and equipment update
Nitrite 5+ ppm
Nitrate 100 ppm
So nitrite has been high for about 2 months now. Will be doing a 50% water change during the next week.
Picked up a new 6 line wrasse :m01:
Received the SAGA water level controller. Still need to set it up. Will...
Ordered the SAGA water level controller. Should be at my LFS by next week :slayer:
I am sure most of you are wondering why I am excited about an ATO. This is due to my nano not having a sump and I do not think it would be possible to run an ATO, so I had to use one on the...
