Hi my name is Big Pete I am a proud Scot living and working in Dubai.

I am a Sales Engineer who took up the hobby a few years ago with freshwater, the natural progression was to move to marine which I did with the RSM 250.

Salt water has been a big learning curve for me but I am enjoying it no matter what mother nature throws at me in the way of algae issues etc...

I was running a freshwater Discus tank for a few years and decided to take the plunge into salt water, it is so much more rewarding than freshwater.

I only use Seachem/Aquavitro products as I personally feel they are the best, I am currently using Red Sea Coral Pro salt for no other reason than I can not obtain Seachem salt.
