Hi fellow RSM owners

I started the hobby about 2 years ago with a second hand RSM 250. I ran that with success but also rookie mistakes that cost me livestock.

Luckily we learn quickly!! So like most i was not long before the itch for more started. I upgraded to a RSM 650 about a year ago...what a joy as the volume of water makes the swings in nutrients and temp more controllable.

With me 250, running without a chiller and T5 lights I had the hood up more than down peaking at 30 degrees in summer and generally ran my tank hot at between 26.5-28.5

With the new 650 came new toys. Great chiller, both cooling and heating, and imported LEDs to fit in between the T5s. I ran the T5s till about April when I went 100% LED. With the chiller and LEDs I set the chiller at 26 with a one degree variance up and down and no heaters switched on as I stay in Western Cape.

With one of the one chiller pipes becoming blocked and me not having the time to de-plumb everything to get to it I switched off the chiller. The temp raised to 27.8 where it basically stays constant throughout the day and night.

Here is the question: What is the ideal temp running fish, SPS and LPS? I know what the books say but taking into account that I ran my previous tank hot, will a general and CONSTANT range of 27-28 degrees be OK long term?

Your thoughts will be appreciated.

I will also be setting my chiller so that it activates if tank gets to 28 so it stays between 27-28.

How long have you been running the tank, and secondly how long at that temp?

Can you also post or PM me some tank pics so that I can see what your corals look like. Even a video would be nice. Thank you in advance

Probably ok if it is constant, I like to run it cooler at 24-25C, more oxygen for the fish, and also as I keep some borderline temperate species like lennardi wrasse and local zoanthids.
