Kinda looks like crap right now but I plan on removing excess glue so that it looks much cleaner. Also need a recommendation for an airline holder that I can place over the lip of the tank. Tubing is not submerged as I do not currently have the required pieces to prevent water from potentially flowing back into the fert bottles (reverse siphon if you will)

I am prepared to meet my Maker. Whether my Maker is prepared for the great ordeal of meeting me is another matter.

very cool.... You can just pry off the old pot with a flat head screw driver or chisel.

Very nice! So were you able to get the flow rate pushed below 7ml?

I actually was able to get it as low as 2ml with the motor controller attached. It's set at just above 4 now.

Honestly wasn't that expensive... Maybe $60-$70. Most expensive part is the pumps. After that everything is like $2-$5

I actually just ordered a nice plastic air tube holder that doesn't look half bad as well as 2 check valves so that I will be able to submerge the tubing. I will probably attach them to the powerhead I am using for surface agitation. This way the ferts are immediately dispersed around the tank.

I am thinking about buying small acrylic tubing so it can look like a set of mini lily pipes to match everything

I opened up the pump and there are 3 large rollers to push the liquid. It's very likely you won't need the check valve as there is always a roller in contact with the hose so there won't be back flow.

I thought about the rollers but I figured better to be safe than sorry...
