Drip dosing plant food

[mikeyw64]

So off the back of another thread just trying an experiment with Sunnyside.

Taken a bottle of TNC Lite and drilled a hole in each lid.

Into the smaller compartment I've inserted a tap off from the air pump.(sat in the cabinet next to the filter and fire extinguisher)

Into the main compartment I've used some airline all the way to the bottom of the liquid and then routed the tube up to the top of the tank.

At the tank end it's then going into a 1ml syringe with needle on to help restrict the flow. Have also used a cable tie to further crimp the supply line.

Took probably best part of 10-15 minutes for the liquid to start coming out and currently "calibrating" it to get the approx 4-5 ml a day I normally add to the tank.

Going to be trial and error

Good luck Mickey. You hoping it will work well with the co2?

I've been adding the ferts anyway daily, just thought I'd try this as a low cost automated method

hmmm so my overnight calibration testing shows I need to slow it back even further as had 20ml of feed come though in a just over 12 hour period so nearly an 8 x dose on where I want to be

That may upset the fish as well.

aye

I'm thinking one of these may give me more granular control over the drip rate than using a cable tie as a crimp.

At the moment its feeding into a 20ml test tube only not into the tank itself so I don't overdose (plus it can be put back in the source container)
