Hi Bro, where do you stay? You may try Oasis from farmart at CCK, look for Kenny, he is nice guy. Recently I have just sent one of my spare 2ft tank to mod as a sump tank. Got them to drill 2 holes & added a few partitions in it. Reasonable price.
I do have a pump call Mebner from Germany. Anyone heard of it? Do PM me if you are interested.
