west can i be frank with you! im sick of being veriann for the day!
Aquatic Systems engineering: Devices and How They Function by P.R. Escobal
Price:27.95
check this book west: i think ive promo'd this before to u guys!
i could prob suggest u look for the thermostats in the temp range that your looking for a start! but to put it simply i would consider cutting corners from things or items that have a lesser impact when things go wrong! u can cut corners on lights, tank stands ect & ect, but filtration & temp are not one of them! just my opinion west> if u still really want to go down that path i'll see what i can come up with, but its not wise considering whats at stake! i know your a techi, but unless u live at radio shack its not as easy as it looks to make it realiable!
