My tank seems to be doing ok and the fish and shrimp are happy. Levels from test strips always report well within safe params. It is planted and I have been doing 20-25% water changes weekly. Currently there are 5 shrimp 1 adult platy and about 4-6 small fry with 2 of them grown to about 1.5cm long. A problem I have is the plants in the tank seem to be struggling a bit and the leaves often go see through and are almost crisp to the touch (amazon sword). Could it be that I am changing too much water and the plants are not getting enough nutrients? I have been supplementing with API root tabs but it does not seem to improve things. I also have some grasses which seem to do ok apart from the big platty pulling them up and eating them... Anyone would think I don't feed her!
