水草情迷

养草近一年,现在水平just so so,现在已经有了根肥、液肥、基肥、二氧化碳系统、照明系统、过滤是大号外滤桶，UV灯也DIY了，效果也还行，日常只是检测PH,但是时不时还是要长些藻，很郁闷，最近又加了支自制的树脂樽。不晓得各位老大还用些什么东东呢？有必要用除磷、脱硝酸盐么？老大们有用测磷和硝酸盐含量的试剂么？兄弟很喜欢DIY，没事情干真是很痛苦。

I think you need to add the test of Nitrate concentration, higher than 20 ppm means your water is polluted with fish wastes and also means an unwell-running of the bio-recyling system. The consquencies of high Nitrate will cause algea growth and fish death, take care!

Thanks a lot.
