AHHH the good well bad old days of 100% waterchanges and complete tank cleans even replacing all filter spongs and wool, dont forget to wash the filter and gravel under tap. It makes me cringe when i think of the things i did when getting into the hobby when i was younger, I honestly dont know how my gourami, anglefish, neons and pleco survived so long. I just never had anyone teach me right and the pet store people well they...... yea ill stop there not getting into the cichlid horror story that finished my fish off
