So much to say on this topic, but sounds like you're on the right track.
Ive got 6 shrimp tanks running, 4 starting up and 4 more tanks w plants and shrimp. I distinguish between shrimp tanks and planted tanks w shrimp in my house.
Shrimp tanks are simple and easy: low light plants and mosses (java ferns, floaters) good filtration, 100% RO and a soil based on the species' needs. I keep 9 different shrimp species.
Crystals and bees on ADA aquasoil, usually, but I have a few tanks w Shrimp Sand and one w EC.
Good bio filtration is important. I use sponge filters in addition to HOB filters in small tanks and am converting some to HMF as I move them to my shrimp rack; and my larger tanks will be on a sump system.
I only dose KNO3 and Fe once a week, 1-2 drops per gallon, and Flourish (micros) once a month, again 1-2 drops per gallon. No CO2 in shrimp tanks.
Feed using a feed dish, 2-3 times a week only, and remove what they don't eat in a few hours. I favor blanched leafy greens, carrot, zucchini and broccoli stems. I use dowme Jake's complete veggie, hikari shrimp cuisine and the occasional small algae wafer broken into small pieces.
I also have shrimp in buckets, literally, as well as tanks. Very easy to keep shrimp. Less is more.
