livingart Posted November 9, 2009 Report Share Posted November 9, 2009 a fridge with hosng coiled in it maybe easier Quote Link to comment Share on other sites More sharing options...
suphew Posted November 9, 2009 Report Share Posted November 9, 2009 Unfortunately neither idea will work well, Pretty much all metals will rust with salt water, even high grade stainless breaks down. The pipe in the fridge idea is a problem because of the difficulty finding tube that will transfer heat. PVC/plastic pipe is a very poor heat conductor. For these two reasons chillers use titanium tube, it doesn't rust and has great heat transfer. But it also why they are so expensive.

bronze-dragon Posted November 9, 2009 Report Share Posted November 9, 2009 You could buy a beer fridge and put your sump inside it with holes for the water in and out Quote Link to comment Share on other sites More sharing options...
livingart Posted November 9, 2009 Report Share Posted November 9, 2009 used a fridge for 18months kept tank at 18 degrees in summer coiled hose in large plastic container full of water inside the fridge tank ran for 4 years on undergravels and old berlin skimmer i did have access to fresh saltwater all the time though Quote Link to comment Share on other sites More sharing options...

spoon Posted November 9, 2009 Report Share Posted November 9, 2009 how big is the tank if its really small you can get a kit off ebay that uses a peltier effect cooler fitted into a hang on back filter i dont think it would be effective for anything over 50l and possibly by the time you buy it and pay for postage you could probably pick up a secondhand chiller here for a lil bit more Quote Link to comment Share on other sites More sharing options...
anthony law Posted November 9, 2009 Author Report Share Posted November 9, 2009 the tank with sump aronud 700 liters Quote Link to comment Share on other sites More sharing options...
suphew Posted November 10, 2009 Report Share Posted November 10, 2009 Have you concidered going tropical marine? Really the only difference in cost is the livestock which is largely offset by the cost of a chiller. Quote Link to comment Share on other sites More sharing options...
anthony law Posted November 11, 2009 Author Report Share Posted November 11, 2009 ive thorght about it.but as a learner as this is my frist marine tank its cheaper if something goes woring as i have all the livestock at my door step, p/s i hope its doesnt go woring but you never know.

Stella Posted November 11, 2009 Report Share Posted November 11, 2009 700L is pretty big, should be reasonably stable. Reading through thread after thread here on good ways of cooling, it looks like chillers are good on small tanks and fans for big tanks. With a sump you could have a fan on the tank and a fan on the sump. Of course you would need to be topping off with fresh water very regularly.

anthony law Posted November 11, 2009 Author Report Share Posted November 11, 2009 you think a fan or two will do it.that whould be cool as i can get my hands on fans , ones that cool computers should work. Quote Link to comment Share on other sites More sharing options...
Stella Posted November 11, 2009 Report Share Posted November 11, 2009 I have heard of people wiring up banks of computer fans Fans can be noisy though. I think it will depend on a whole bunch of things though: The room should be cool to begin with. The surface area should be vast. If your tank is tall and thin forget it. You want maximum water surface area for evaporation. Your fish should be rockpooly. They can be a bit more hardy when it comes to temps. The aquarium hardware should give off as little heat as possible and insulate the tank thoroughly. Of course I haven't had any experience with marine fish. Others will be able to give you more specific advice. Quote Link to comment Share on other sites More sharing options...
Ira Posted November 11, 2009 Report Share Posted November 11, 2009 I think a bunch of computer fans is an expensive, inefficient way of doing it if you can use a desk fan from the warehouse for a fraction of the price that blows FAR more air.
