FYI - I think we had someone replace a small chiller here on Nano-Reef with a Peltec last week. His tank temp shot up to 95! He thinks his heater failed. Anyhow he bought the Ocean 150 Peltec. Hopefully he is in good shape now. It would be good to hear from you. These units are perfect for Nano setups. Very small, quite and they kee the temp very stable.
