wait till your dkh drops to 7 before starting dose. i started dosing 4 times equally threw a 24 hour cycle then as tank started to mature switched to nights. now 2 years later experimenting gradually shifting #2 to daytime while keeping #3a and #3b nights. but best just keep it simple equal amounts as many times as your doser can handle while maintaining accuracy.
after cycle is complete start testing your dkh when it drops to 7 then start dosing acording to the directions: core 7 TRITON method is 1ml per 100l(26 gallons) of each 1, 2, 3a, 3b in a high flow area of sump at least 30 minutes apart
