Before this thing gets completely derailed I'll give you my opinion on your question Psyire (and the few that have emailed me about this topic). The Biotopus II is a stable, mature and flexible product. The Biotopus I came out about 8 year ago and we still offer this unit along with the new biotopus II. So I don't sound like a complete commercial for the Elos unit, the IKS is also a mature product as well as the Aqua Controller line. The Biotopus does not have a webserver but the internal ability exists to add a web sever and it is being developed. It does have SMS available now. The serial port also doubles as the connection to the SMS module. Because this system is very mature and stable, firmware updates will not be very often and a very inexpensive serial to USB adapter will work, if needed.
On board but not yet implemented:
Infra red port to control a remote display or remote equipment such as switching off the TV
Dedicated port to add up to 255 additional plugs/equipment.
Special probes port for new probes as they are developed.
There is more I just can't think of it now
The biotopus is very flexible and includes unique things such as:
over 1,000 biotopes that can be simulated. not just lights and temp but everything.
built in dosing pump functionality for up to 6 dosing pumps
built in top off controller and float switch. The float switch is made of blown glass.
connection for moonlight to simulate moonphase
connection to control variable tension including dimmable ballast or variable pumps
connection to external dialer (you can connect it, for example, to send the alarm via a home alarm dialer.
SMS will give you updates, alarms for things out of parameter and you can control assigned equipment via a GSM phone.
Lux probe to check bulb condition and assist in coral placement
If you use our aquaplanet line of lights you can add an interface within the light fixture to allow you to control the light(s) with a simple telephone cord to the biotopus and one power cord. (Allows up to 3 groups to be controlled indivdually. Example. If you have the aquaplanet II T5 with 6x 39, you can control 3 groups of 2 lights to fit your needs with one power cord and one telephone cable to the biotopus.
The materials and construction really must be seen to appreciate. The body of the biotopus and the SMS module are aluminum and everything is custom made with no commercial parts as you find in most every other controller. The black polished front and silver buttons are very nice, as well. The internal components and probes have been certified in Italy to be immune to outside disturbances. We also produce a special application for Municipal water test, lab and industry process. There is more but I'm getting hungry...........
In fairness to the Aquatronica the price difference reflects how different these products really are and it is a bit unfair to expect it to compare favorable to the biotopus II. Not sure of the US prices for the AQ but in Italy the AQ is sold direct to the customer for around 550 euro and the biotopus is around 1850 euros through retailers and distributors.
I will be back in Europe for Interzoo and I will post in the Elos forum the new things that will be introduced for the biotopus II, among other things, if you are interested. Once again, I don't want to derail your thread but I thought if I got to it now, this thread can continue on about the AQ, which it should. Thanks, Jesse
