Which model to choose between the chillers for the aquarium?
Among the new and especially among the used, since the cost is estimated between 250 and 500 €.
Goal is to keep the summer temperature below 28 °, the ideal would be able to have it at 26 °, but also a couple of degrees higher animals certainly can bear and thus consume less watts of light, while 30-32 ° are too many and if kept for 15-20 days can cause serious damage to animals, sometimes irreparable, resulting in death.
It happens for example to find out who dismantles the aquarium, for moving, more often set up an aquarium larger, 1000 or other reasons, and among the various accessories also sells air conditioning, big boy, heavy enough that device that serves to cool the 'aquarium water in summer.
The choice is important, because these air conditioners have significant costs, as well as become important figures related to animals that may die without a cooler high temperature.
Personally I have lost 3 corals for aquariums without this accessory this summer, and in my aquarium are all small pieces, but in their small had a value of at least 100 €, not to mention that water values ​​have deteriorated following the death and ... a minimum of sentimental value.
Cool water in the 3 summer months is therefore essential for those who breed LPS and SPS corals, see which models are suitable for aquariums 300-500 liters, better still take it bigger and not smaller.
Even for consumption, seems to consume a little less, but can remain on much longer because his power is not adequate ...

• TECO TR10 (again about 450 €) for aquariums up to 300 liters (in my own would be minimal, perhaps a better TR15 used ... which DaniReef wrote in the past have tried for a long time personally)
• Artika 300 (again about 300 €) for aquariums up to 200 liters (really too small for my 80x55x55, the risk of not being able to keep the temperature below 28 ° is real
• Hailea HC-150A (again about 350 €) for aquariums up to 300 liters. TECO China because of cheaper, consume little and seems to work well on some forum reading, I would say that the 300 to 250 liters will stoop to stay calmer, better here then the model used HC-300, wanting to save money

And do you not compute? In the case of the refrigerator, for those who have read articles on various Autocostruzioni in Italy and abroad, is unlikely to be able to build something contemperaneamente efficient, economical and safe. Why do not we also safety aside, is that relating to the electrical part, is related to the connections that bring water from the air conditioning unit and vice versa, without forgetting that the chiller is typically used in marine aquariums, with rooms capable of rapidly oxidize all metals that are not expressly suited for use in water.

And the fans? Some will think that I have not considered the use of fans, maybe something like the models and technology offered by TECO-chill (but are designed as "economizers", ie as an aid to systems already equipped with a refrigerator. The problem with these solutions wind / evaporation, is precisely that they consume so much water. And for long periods of absence, as in the 2, 3 or 4 weeks of summer holidays, it becomes difficult to provide a water supply sufficient for the automatic refill system .
Council however, absolutely, the use of a tangential fan for those who use metal halide lamps, so comfortable in the winter to heat the water and save on the consumption of the heater (otherwise said thermostat), but deleterious the summer to keep the temperature low ...

Needless to comment on the completeness of ' friend Danireef article and the wealth of photos, then I invite you to read his post with analysis and comparison of movement of the pump Tunze Stream 6105, electronic pump interesting, new, very efficient, suitable for aquariums between 300 and 500 liters, in fact, able to move from 3,000 to 13,000 liters per hour!
Moving the aquarium water with this pump should be a pleasure.
Personally I prefer the less aesthetic impact and thermal Vortech 's Ecotech Marine (in this case the comparison should be made ​​with the model MP40).
Among the accessories for aquariums marine pumps movement are really important, both as a model selection to stir the water well, both as a percentage of the cost because they are of approximately 10-20% of the total expenditure for setting up a marine aquarium reef, especially with the presence of corals SPS.

This pump has a movement cost of just under € 300, but remember it must be paired with a multicontroller to give their best, that is, to allow us to adjust the speed and frequency of operation, such as the 7096 that costs little more than 100 € . And, above all for use more than one in combination.

The WRRK, in collaboration with the magazine Coral , is organizing the 2 nd Meeting of the town of Fiumicino Marina Aquarium. Behind this lies the complicated acronym " West ReefKiping Rome ", a group of enthusiasts who later became association. The aim is to be the meeting point of all marine aquarists in the area west coast Rome Rome (Fiumicino, Ostia, Acilia and surrounding areas), even if we include among the registered members of other parties in and around Rome.

The event will be held on the dates of 3 and 4 December 2011 at the premises of the Maritime Port Authority Station located in Fiumicino - square Mediterranean

Sympathetic to the initiative of FAIR, where everyone can bring (except traders) accessories for sale ... there will also be animals, then fish and corals, Fungia so I could bring some of my work ... and maybe a couple of cuttings of Xenia and Discosoma, is also a good opportunity, I think, to go shopping!

The program is very simple, however I find interesting. I think to go Sunday, I care about most interventions, might be able to go along with a couple of friends of the Club Ittiologico Roman ...
