hmm today feel free & found this somewhere....

it's not about the brand but the dye fluid in general.
Pre-Mixed Fluids.Another option to consider is pre mixed water/additives, but be warned, the dyes in many of these fluids can congeal around the insides of your water blocks and cause a blockage and also stain tubing, reservoirs and other acrylic items. Based on those points, I do not recommend using these kind of products unless you absolutely need to have coloured water in your reservoir.
Dyes.Again, these dyes can look great for a while, but we've see many people complaining about acrylic blocks and tubing becoming permanently stained, fins/pins inside blocks becoming clogged and even dyes losing their pigments over time. I still have a pair of perfect seal barbs that have their threads stained pink from some orange dye, no amount of scrubbing or soaking would remove it! If you aren't too bothered about any of the above, then they can be an unusual and arguably attractive addition to your loop - My advice here though, is to use coloured UV tubing instead.
Avoid mixing metals.Copper and Aluminium don't play nicely in water. You may well end up with Galvanic Corrosion unless you use some kind of corrosion inhibitor. There are many on the market, such as G11, Zerex, Feser, but ideally though, try and keep all your blocks the same type of metal. Please ask on the forums for advice on specific gear.
