purely h2o ro/di question

[lockrookie]

i recently purchased a unit from a fellow reefer and regretfully it needs some replacement parts/media. this is a new thing to me so im not sure if anyone else has used this product. the only place i can seem to find the parts is from florida. but i was wondering if anyone here in canada carries or carries the parts i need.

i need to replace a couple of the canisters due to breakage they may be fine but i may as well get replacements just in case.

as well as i need the 3 filter medias and a membrane. if anyone has any helpful thoughts or ideas where i can aquire these things pleae let me know

thanks in advance
jeff
