Tank cycled 20-21/04/20 as nitrites 0 ppm and nitrates 5ppm.
Large 80% water change

Moved peppered and bronze corydoras to this tank to medicate with Kanaplex and nitrofurazone combination as fish unresponsive to round of tetracycline, melafix and pimafix. Methylene blue dips also unsuccessful.

Diagnosis: unilateral and bilateral popeye

Rationale for kanamycin and nitrofurazone tx being addresses both facultative anaerobes and common disease causing aerobic bacteria.

If doesn't work, will purchase seachem paraguard; has malachite which may be lethal in some corydoras apparently; jaudicious use warranted.
Measured Nitrate at 5 ppm
Measured Ammonia at 0.00 ppm
Measured Nitrite at 0.00 ppm

Nitrite spike dropped to 0.25 and nitrate remained at 5.0
Added 1ppm ammonia to feed
Added stability

Appears cycle is almost done, just waiting for all nitrite to 0 out and nitrate spike for a large wc

Old tank cracked by dad yesterday 16/04/20
Purchased new 3ft 182 litre tank but it leaked overnight, decided to return it

Purchased petworx 50x30x30 tank 45L at aquatico
Tried to salvage cycle from HOB filter w sand, plants and tank water. Added one 50w mini heater as well to try get temps up.
Tested parameters - 0.5 ammonia, 0.25 nitrite, 5 nitrate.
Added 9 drops nh3 to achieve 3ppm ammonia
Added cap of stability

Measured Nitrite at 0.25 ppm
Measured Ammonia at 0.50 ppm
