I have a kessil ap700 and 2 vortech mp40’s. Quiet drive model (newest ones) The light was used for about 2 months at 5 hours a day light cycle. (Hardly used) The powerheads were used for roughly the same amount of time usually at there lowest settings. (My tank was a 55 gallon long) Message me or post on this with offers. I’m not going to set a specific price because I’m not sure what a trading/selling price range would be for these.
