The splashguard may include a main channel formed by an elongated base plate and side walls extending generally orthogonally from the elongated base plate by a first distance. The splashguard may also include a first end channel formed by a base plate and side walls extending generally orthogonally from the base plate by a second distance greater than the first distance. The first end channel may also be formed by an end wall extending generally orthogonally from the base plate by the second distance. The splashguard may further include a second end channel substantially identical to the first end channel. A first flow path may be maintained between the elongated base plate of the main channel and the base plate of the first end channel. A second flow path may be maintained between the elongated base plate of the main channel and the base plate of the second end channel. ## Claims ### Claim 1 A splashguard for a tank, comprising: a main channel having a first open end and a second open end and formed by an elongated base plate having a first length and a second length and side walls extending generally orthogonally from the first length of the elongated base plate by a first distance and configured to connect to an upper wall of the tank;
