Restarting back my hobby after few years. Due to rushing for CNY 2017, tank sized 5x2x2.5 was brought to my house on 20/01/17. On the 21/01, a 12" arowana and 2 rays, 8"and 5.5" was introduced into the tank. And another 3 more rays (all about 8"), a 8" Harlequin Lancer catfish and a 9" dwarf Oscar was added about a week later.

Ammonia always showing high reading. WC almost everyday from 30-80% and yet still no signs of improvement till now. Usually the reading will be from 0.25ppm to 2ppm after WC and double up every 6-8 hours.

Just installed a Hydra Stream 2 to my tank on the 12/02/17 on the 5,500lph return pump. Ammonia reading is at 8ppm and WC of 90% done and reads 1ppm now. Lets see what Stream2 can do for me.
