    Hi Guys

    I'm new to the hobby and need advise please.

    I have a 90l tank, with some rock and clowns. So far my tempreture has stayed constant at 25.5 degs without even trying. The last 2 days, we have had ambient temps of around 35 degs, which see the tank temp climb to about 28 degs!

    I have a lid on the tank that contains all the lights. I am not running a sump, just a cannister filter with a in tank protein skimmer.

    What is the best way to keep the temp down of the tank? We will be going away over the December holidays for 2 weeks, so need to find a way of keeping the temp down,a s there will be no one monitoring the tank, except for feeding.

    Any advice will be appreciated!

    PS..... Chillers don't really fit the budget at the moment!

    Welcome to MASA!
    Having the top of the tank open and adding fans does help, but will increase evaporation a lot

    You can buy an ST1000, it comes with a temperature probe, you can connect heaters to it and fans(like pc fans) At a certain temp the heaters gets switched on and at the desired temp the heater gets switched off, at a high temperature the fan/s get switched on and get switched off at desired temperature.

    All the temperatures can be set to your preference, evaporation will go up when using fans but it works. This setup also negates the problem if your heater malfunctions and stays on as power is cut off to it when the controller reaches the set temp.

    Thanks guys. What is the temperature variance that the fish will be able to handle? Yesterday tank went from 25.5 to 27.9, then by this morning its back down to 25.6?

    If it's not sudden changes it should be fine. Coral may stress a bit more. Experts can verify.

    I would go with a big fan and good ATO if the temp isn't too high
