Reward calculation problem with setup open-ethereum-pool

[retal]

I setup open-ethereum-pool for MusiCoin.
Musicoin block rewards is 250 coins, but GUI still shows reward 5.
 Here is my unlocker.go file:
const minDepth = 16
const byzantiumHardForkHeight = 4370000

var homesteadReward = math.MustParseBig256("5000000000000000000")
var byzantiumReward = math.MustParseBig256("3000000000000000000")
var constReward = math.MustParseBig256("250000000000000000000")
