I buy 1L liquid to put in my water column with bubbler included and used ca ... nothing bad, you obviously have much less effect a faith Diluted in water.
But hey if I should put the pure liquid, it'll cost me candy because I put still more than 5L of water in my water column ...
Column of water without Mahyems: [...]
Water column with Mahyems: [...]
The liquid is "biodegradable" so the specific particle diluerons after about 30 days (1 month) if the liquid is in the open air.
Basically Mayhems keeps a maximum 2-3 months the bottle open faith.
At the end of it's 3 months, you risk seeing a single blue dye enough "trouble".
Here, finally I would say that is dye / liquid book is especially for watercooling (without angled nozzle if possible)
Have fun. ;)
