Cooling solutions

Dears,
I have a tank with the following dimension : 100 * 60 * 50(h) cm
the tank is rimless without canopy
with a total net volume (sump included) of 300 liters.
The tank is illuminated by 8 X 39w T5 (matrix Giesemann).

I already have a Profilux 3 and i have 2 power Sockets free and one L Port free.
My temperature during summer was up to 27.5° , i had a temp. light dependant set on 6 t5 to limit the heat.
So, i believe that i should just reduce from 1 to 1.5 degrees the temp of the tank during hot periods.
I am living in belgium, meaning that the hot days are rare: 15 days per year maximum :-(

What are the pros and cons of using the propellerbreeze from GHL or another brand (plugged in a socket) ?
What do i need ? 3 , 4 or 5 fans ?
And if i go for a ghl solution, what do i need ? PL-0265 , PL-0716 / PL-0717 / PL-0718 , do i need a L cable ? or it's included in PL-0265 ?

When i use a propellerbreeze, can i still use the temp. light dependant feature ?

Thank u in advance for your feedback or experience

It's always a bit hard to say exactly which size is suited best for a customer's tank - since
many conditions have an influence such as canopy yes/no, how much heat is produced
through lightning, is it a penthouse, by how many degrees shall the temperature be reduced etc.

Yes, you only need the PL-0265 (Propeller Control) + the Propeller Breeze. You need one channel of an L-Port.

Yes, both functions can work parallely.

Thank u for your answer.
I was hoping that some profilux users can share their experience on cooling with the propellerbreeze.
thx
