Looking for 1 or 2 Koralia #4's. One of my pumps for some reason started to spark inside the water!!!! I think thats why my sailfin tang just died last sunday and I couldnt figure out why. Now i think i know why! So, I yanked the powerhead 802 out and trashed it! I want to get some Koralias now, so if you have one that is fairly new or in great shape let me know! If no one has any, a suggestion to the cheapest place would be nice! I didnt expect to buy one this weekend but now i need to! LMK!
