Seiryu Stones Question/Advice
Have an established 120g hi-tech well planted tank with 7 adult discus, few tetras, algae eaters, loaches and few hundred red cherry shrimp.
I do CO2, root tabs and flourish excel. Substrate is ADA Aqua.
Tank has about 20 lbs of Seiryu stone which I put in about 18 months back. Planning on adding another 20 lbs of seiryu stone. These were untreated per the store owner.
Question: Is it a good idea to add Seiryu stone in an established stable tank? Read that it'll mess with the parameters.
Is it worth adding and messing with an established tank?
If Seiryu is not worth the issues what other stones are best that do not change the tank parameters?
Thanks in advance.
