hello, im from indonesia and i have some questions (sorry for my english)
1) I have RO unit but its old , i tested it and found out i have 20tds (tested with 2 tds pen), kh5 , gh5 . my father wont change the filter and membrane if its only for shrimp :/ , so do you think 20tds can have kh5 and kh5 ?
2) what level of kh or gh if the tds is 20 ?
3) my shrimp colony is getting smaller due to high level of nitrates 0.25mg/L , i tried to put some frogbit but they are dying (now im using inert substrate and low dose of seachem flourish. before i change to inert, im using active substrate and the frogbit multiply so fast). tried some stem plants but they didnt do well.
why this happen and how to reduce nitrate beside water change ?
4) In my country, there is no KH+ GH+, only GH+ . how if i have neocaridina that need KH ?
