Hi think I made a mistake, bought 5 amano shrimp, and will put them in my Quarantine tank, and will come over to my 350 l tank after 4 weeks, but read afterwards that you only can change 15% water every 14 days, the problem is the aquarium I am filling up with fish, becomes a 350 l Community aquarium where I have been recommended to change 30-50% water a week when it is stocked with fish, what is your experience about changing water with Amano shrimp?

My thought was that maybe I can hold the nitrate down by my Pothos and lucky bamboo and my biohome ultimate media, which all take away the nitrate, then maybe I can settle whit 15% water change every 14 days, but have heard that your fish are more exposed to diseases when changing so little water, do not know if whats right, do you guys know?

Also i have seen that you have to measure TDS and put something called Salty Shrimp Bee Shrimp Mineral GH + in the water and use Reverse Osmosis System, is what necessary?
