Clombo drop checker fom aqua essentials

[RudeDogg1]

Has anyone used these? The instructions arnt that clear I'm not sure if I'm ment to use 4dk and the solution or just the solution as it's only tiny. I'm sure it's just the solution on it's own just wanted to check

I havn't used the colombo version but i would say you definitely need the 4dkh solution
