Hi

I am new to aquarium computers and although I have been reading about them I am not 100% sure of what I need.

I would like the computer to check the temperature of my reef tank and control it using the heater and some fans. I would like it to monitor the pH and at a later date also monitor conductivity. I would like it to control some dosing pumps and switch on/off the lights of the tank (metal halides) and the sump (LEDs). I would also want (maybe later on) to be able to remotely access the computer from my phone/laptop to see the measured parameter values and to switch on/ off things if needed. The connection to the router needs to be wireless.

Will a PII plus be able to do all this and if so what bits do I need for remote access and wireless connection to the router?
If I go for a PIII instead what extra bits do I need?

Thank you for your help
