Hi everyone,
I recently changed my substrate from soft pebbles to sand. I used Argos play sand to do this. Previously my tank was fully cycled, it has been running 6 months but the filter was seeded with media from my old tank and it's cycled filter. I initially had a short mini cycle that lasted about 2 weeks which I dealt with by changing water and adding King British Safe Water.
Since removing the pebbles and cleaning the tank well I've been concerned about another mini cycle starting and have been keeping an eye on my fish and my nose close to the water!
Last night I could smell ammonia so I did an emergency ammonia test. It came out at about 0.50ppm so I immediately changed about 35-40 litres of water. I only had enough stress coat left to do a maximum of 40 litres - empty bottle has now been replaced.
This morning I did another ammonia test and also tested the PH. Ammonia came out as around 0-0.25ppm and the PH was only about 6. The fish are all acting normally, lively and no signs of ammonia poisoning so I am assuming that the low PH reading is keeping the ammonia as ammonium which is less toxic as we all know.
I've now decided to test out these Evolution Aqua Pure balls and will be adding 6 or 7 balls directly to my filter in the next few minutes. The box directions suggest adding between 5 and 10 balls for 100 litres which is why I am adding about 7.
As I changed quite a bit of water last night and the fish are not unwell in any way I have decided to leave the water as it is (whilst keeping a close eye on it and the fish) and just add the balls.
I'll test the water again tomorrow morning and report the results
