Got the fish

The price was SR5 per goldfish, which is $1.3

Got a bit crazy today and went to get some goldfish, I asked for 10 and the pet store gave me 13, if I counted them correctly :) 

First, I needed control over the time it takes to fill and drain the grow bed. So, I got a splitter and a valve today, to help me control the flow of water coming from the fish tank, to the grow bed. The splitter will give me a way to just returns the water to the fish tank, and the value will let me control how much water is going to the grow bed.

This "T" splitter is to divert water coming from the water pump. Up goes to the grow bed, left returns to the fish tank.

This valve controls the amount of water coming to the grow bed. It allows me to control the filling time of the grow bed & functionality of the siphon.

That's it.. Everything is working well, BUT without the hydroton.. Once I add it to the grow bed, filling and draining will be much faster and I'll have to recalibrate. 

Stay tuned for the hydroton test :)
