Hi there,
My name is John and it is time to introduce myself been a member of this forum sins January 2013.
120 ltr aquarium got it of my daughter in Christchurch who gave up when all the fish died after the earthquake.
Had a lot of trouble with the plants they all went black and died. Lots of water changes put phosphate lowering stuff in the filter got some new plants and a baking soda and citric acid co2 system and it all looks good now no black stuff anymore just green algae.
My latest phosphate reading came out 0. PH was 8.6 so put peat in the filter and hope it will bring it slowly down a bid without harming the fish. Wait with putting in more fish till I got the water the way I want it. At the moment 1 pearl goerami, 5 tiger barbs, 1 Siamese algae eater, 4 neon tetra's, 1 harlequin rasbora (2 have died).
