Like a lot of things in life, people that do not know what their doing, can make something so simple to very difficult.
My wife and I are saltwater fish & reef hobbyists, and here as well, people make problems for themselves for no real reason. Like some people try to rush the simple process of cycling a new systems nitrosomonas with loading it with several fish. Then they say the ammonia level spiked, killing the fish,...."why, what happened" ? Because you did not follow the cycle process, nature takes time ! Etc...
Same goes with our cars and it's systems, like a engine package that works together, including a
oil pre-lube system. Hook it up correctly and use it properly. Like my question about wiring the warning lights. Rush to get it done,...you're going to have problems.
