Red Sea Max - Temperature fluctuation Issue

[Borderjumper]

I will get back at you this afternoon when work allows. And yes the fans can be set to come on with the lights.

You just might be my savior Borderjumper. Much appreciated.

If you look under the timer cover, there are two rocker switches. make sure they are both in the l position, this sets the fans to come on when the lights are on.. Now saying that, I don't use the lighting timer, I manually switch them on and off with the rocker switch in the control box. You will have to read up if this works using the timer.

heat is always an issue with a stock RSM... Have you ever looked at just how huge that stock skimmer pump is? As well as the pumps for circulation?

I removed the stock skimmer and am using a little bubble magnus, and I also took out the left side recirc pump and put in an eheim pump.. And i leave the flap up in the back.That pretty much solved my heat problems, except on the very hottest summer days. When it's mega hot I put a piece of egg crate over the little open area in the back left side ( this is with the back lid thing flipped up) and set an old computer fan on it on a timer that runs it 5 minutes an hour during the day.

Hope this helps

Shelley great idea. So having a overflow on that tank solve the problems of having the system heat up. and second i think that is why they state a place for a chiller in the compartment below. Cause it does heat up.

There is a little plate on the back, top right hand that pops off, and a connector kind of thing pops in. It has two elbows with barb connections for the chiller to hook up to. I've always wondered if you could mod that in a way that you could use that for the sump in and out?

they have a cheesy little fan that plugs in the back.. 20$ worked fin for me.

I don't think this isn't entirely correct. Unless it's different on some models of the RSM250. Mine is like this. One of the rocker switches is for the cooling fans (rear) and the other is for the LED lights. The rear cooling fans only have the ability to be turned on and off manually via the rocker switch. I leave them on 24 hours a day. The fans in the lights are turned on and off via the timer and/or the on off switch on the timer. If the lights are on, these fans are on.

If you bought the unit used check to ensure all the fans are operating at full speed. When I bought mine I had to clean them and replace some as they weren't operating optimally. Make sure the fans for the lights are installed correctly as well (in case someone changed them). Two should be blowing across the bulbs and the other two should be pulling that warm air out the opposite end.

I've heard this as well but it's decreased if you have the new style skimmer pump. The Sicce supposedly reduces the heat compared to the older Hydor pump. I believe there are Sicce replacement pumps for the circulation pumps as well.

I also don't use the stock skimmer. I went with the Deltec MCE-500 so I leave the back flap open too. I also leave the front feeding door up as well as that is where my autofeeder sits. That probably allows more of the heat to escape.

My apartment is quite warm and my temperature stays fairly stable within a few degrees day and night.

This is not correct... at least on my RSM250 (4 months old). Bottom rocker switch is for manually turning off/on the back water cooling fans. The top rocker switch is for switching on/off the blue LED moonlights. The instructions on page 22 of the RSM250 instruction book also confirm this.
