does anyone have any advice to give me about my seaclone 100 that hasnt already been said (i know throw it away is the general thing said) but i got swindled into buying one (for $150 at that! (i know i know)) and theres no way im getting what i put into it and theres no way i can get anything else anytime soon, so im stuck with it. ive got the algae sponge on the return to min bubble output. im kinda scared to mess with the impeller to do any mods there, and same with the innermost tube. ive changed the air intake valve to a better one, so i have better fine tuning now (essentially i left the other one on too and placed another tube and valve so now i have to controls) and am contemplating taping the cup to the unit and removing tape only when im cleaning out collection cup. im also skeptical about adding a diffuser stone in down through the cup lid cuz i feel like this will only produce a wet skim and im looking for a very dark mucky kind of skim, so far i cant even get the bubbles to climb the neck of the cup. they just sit at the water line and fizzle and pop
