Evaporation And Effects Neocaridina Shrimp

    I'm setting up a 5 gallon shrimp tank. I tried a versatop lid but it is about ⅛" too long... So here is my dilemma.

    As water evaporates in my tanks, I just top off as needed with my tap water. However, it is my understanding that this increases the concentration of minerals in the water.

    Is this detrimental to neocaradina varieties? I don't fully understand TDS but know shrimp are sensitive to fluctuations. I've only ever kept feeder shrimp with... less than laudable results... but attribute that to poor genetics and neglect during shipping.

    Is an open top ok? I've considered getting the versatop trimmed but wouldn't know how...

    If you are doing weekly water changes that should be fine, It won't evaporate that much in a few days.

    I have been watching Mark's Shrimp Tanks and he recommends only 1 or 2 water changes per month, in relation to TDS. However, most of his shrimp are Caridina varieties, which from my understanding are more challenging to keep.,

    My cherries get a 50% water change once a week, (planted community tanks) plus a top off if necessary. If your numbers are higher due to increased minerals you can do a couple of back to back changes to reset them.

    Should I get a TDS meter?
