Fish Fanatic
Yes I was in the fish shop today to buy some sechem purgen and compare tetramin pro crisps vurses the newer tetramin crisps. I currentlly feed JBL flake so it's all reading the small print trying to decide. Anyway I had them open up a pro 2 box, It has the same smaller hose size as the PRO one and my 2215 the 12/16mm or 1/2 inch. On eheim's international site it has pds of spares and lists the classics pro and Pro 2 as needing the hose labled 405940= 12/16mm or 1/2 inch. My pro 3e which has the larger 16/22mm 5/8 inches size has the spare part number 405943.more tubing talk:
finally making it up to speed that there are 2 sizes somewhat standardized:
1) smaller size with inner dia 12 or 13mm = 1/2 inch
2) larger size with inner dia 16mm = 5/8 inch
My dealer said the older pro1-2222 would not fit the hydor 200w they had, but that the same hydor connected perfectly to the pro2-2026. So I now think that the dealer must have the 5/8" version of the hydor200 and that the pro2-2026 must use the newer 16mm hose size. Do you guys think its possible that the pro2-2026 has the larger (16mm = 5/8") hose size?
(also, I now see what you are saying, that the intakes and spray bars fit to either of the hose sizes in a standardized way, whereas at the other end of the tube the dual taps are either 1/2" or 5/8" except that there are kits available to take older 1/2" taps up to 5/8" if you need to)
(if all this detail seems absurd, it has to do with communicating with dealer/distributors on other side of continent.. can't run down to the shop and chat! so all a great help to me and fun knowing that the forum has the collective smarts to produce the details.)
I think your fish shop people had some other problem as the hoses sizes for pro 1 and pro two are identical.
