Hey
@Priscilla Sorry about missing your questions, as
@Wander mentions about adding powdered cuttlebone it will spike very fast, i dont know if it would be stressful for the shrimps as ive never made the PH swing that fast but i would just add a lump to the tank and let nature take its course, if you are worried about aesthetics i would just buy some ocean rock and put it in, this will solve the issue too.
Your tank is big enough to house the shrimp you have and is big enough to have them breed nicely, as for food i would only feed them once a week and small (tiny) amount. What doesn't get eaten in a few hours i would net out so it doesn't break down and foul the water.
I'm glad you are enjoying the forum
