Hi all,
I upgraded on Sunday from a 50l/13g tank (of which lid and lights got broken by cleaning lady...) to a 2nd hand Juwel Rio 180 (180l/50g).
Kept the filter of both aquaria submerged in tank water during the transition. and installed both filters in the new aquarium to have maximum amount of bacteria.
On Monday NH4 and NO2 were 0, NO3 was 20ppm.
Today, NH4 was 0.75ppm, NO2 0 and NO3 still about 20ppm.
I changed 1/3 of the water today, but after measuring about 5 hours later NH4 seems to be at the same level. I notice some fish are swimming more frequently at higher levels and where bubbles and filter are.
Tank contents:
- 6 plants
- 1 shark catfish (yes too big for tank but came with tank...)
- 1 red tail black shark (ditto)
- 1 red phantom tetra (ditto)
- 4 gold dust mollies and 7 or so babies
- 5 neons
- 1 hillstream loach (sewellia linoleata)
One of my mistakes was feeding the fish bloodworms for the first time but obviously gave them too many as a lot remained on the bottom (though this AM they were gone), I think that contributed to the problem.
What would you recommend I do, apart from changing water every day until the problem is gone?
