I need some help. My tank is a 29 gallon saltwater. It is at 80.7 degrees. Is a chiller worth the money?

Or tried orienting your powerheads towards the surface for agitation (resultant evaporation helps to cool as well)?Have you tried a fan blowing across the top of the water surface yet?
Sry, math nerd alert incomingOr frozen water bottles? I'm betting one 16 oz bottle will drop it 1+ degrees.
At that temp you are fine.I need some help. My tank is a 29 gallon saltwater. It is at 80.7 degrees. Is a chiller worth the money?
I have a glass top to keep my cats from jumping on top or inside. A fan would not do a whole lot I think.Have you tried a fan blowing across the top of the water surface yet?
If the bottle contained antifreeze at 0, you'd be correct, but there is a phase change which is not included in your calculations.Sry, math nerd alert incoming
Assuming the bottle is at 0 degree F, that means its an 80 degree differential. A 1 gallon bottle would mean 1/30th of the combined 30G volume. So, a 1 gallon ice at 0 degrees will reduce the temperature by 80/30 = 2 2/3 degrees. 16 oz is 1/8 of a gallon, meaning a 16 oz bottle, assuming 100% heat transfer, will reduce the tank by only 2/3 of a degree, disregarding the impact of any other heat source.
This is an approximation. Im not a physist and not completely considering the laws of thermodynamics
I have my wave maker pointed at the service and my return wand for my filter pointed at the service too.Or tried orienting your powerheads towards the surface for agitation (resultant evaporation helps to cool as well)?
Not sure. This is my first saltwater tank. I have a freshwater tank that’s the same size and it’s 81 and my fish are great. I’ve only lost 4 fish since I started it in March.At that temp you are fine.
My 120 runs 79-82 with no issues.
A fan as suggested is a good way to reduce temps also.
What is your desired temp?

I’m thinking about using a hang on the back filter that I have lying around and modify that with something to use as cooler.see where you are saying fan and changing flow across surface aren't options. Not yet mentioned
- reducing temperature of room where chiller located
----- window A/C unit costs less than tank chiller and is multi-functional
---------- both room and tank are cooler
- canopy top across tank top instead of solid glass tank top
- heavy duty screen across tank top instead of solid glass tank top
----- something supporting cat weight
----------- aluminum gutter mesh from home improvement store
Those fan and water bottle suggestions are definitely less costly options to reduce temperature, but yes chillers work. IF you decide to go with chiller, you want to size chiller for your tank (manufacturers website has calculator), but at 29g likely even small chiller would work for you. I use a 1/4HP Artica for my 180g - I'm in Texas and its hot...
I think as long as you stay away from cold loving fish (deeper waters usually) you may be fine as you are just on high side of normal.
I must have fallen asleep that one day 25 years ago when they talked about phase change in High School lol.;FacepalmIf the bottle contained antifreeze at 0, you'd be correct, but there is a phase change which is not included in your calculations.
