Is the LR in the tower a future concern for Nitrates?

as long as the pieces are large/irregular enough and dont nest so as not to cause clogging. regardless of what you place in the tower the main goal would be to reduce the accumulation detritus/debris. if this occurs then you could have a problem with nitrate. the key would be to allow the debris to flow through the filled area so that it can be
a. collected by a mech filter that can easily and regularly be cleaned
or
b. be removed by the skimmer.
or a combination of the two.
time wise, the longer debris is allowed in the tank the longer it can remineralize and release nitrates into the water as it decomposes.
