I have two ice cap 1k gyres up for grabs. One unit is less then 2 months old and the other is less then 6 months old. Both only run no higher then 30% the entire time since they're just too powerful for my 80g shallow reef with sand. I also have a controller extension cable new never used that's an 18.00 value to go with the set. Both are still currently running on my display tank in single propeller mode but I got the second propeller to each and all accompanying parts. I'd like to sell as a set with the extra controller extension cable im asking $200.00 (shipped and Pay Pal fees included). Once bought I'll pull the units from my display and soak in citric acid over night and ship out the following day.
