The other option is to buy a fire extinguisher (make sure its reconditioned and labeled, should be about £20-£30), a c02 regulator like this (£29), a nut and tail (£2.59) to reduce the dia to suit 6mm tubing, a needle valve such as this, although go for a Clippard if possible as they cost about a tenner, but you need the screw in adapters for the 6mm tubing try Westgroup, have to buy the adapters in packs of ten and you only need two, but the valve and adapters should cost about £20 and a de-fusser.
As long as you use c02 tubing and set the reg on the fire extinguisher to output a very little amount, you only need to use the needle valve to fine tune it and no need for a bubble counter as a you can check the c02 in the water using thiscalculator, all you need is a kh and ph test kit and very accurate.
With regards to a solenoid valve, you dont really need one as you can use an airstone at night to up the o2 in the water and reduce the c02.
Just a little cheaper than the proper aquatic c02 setup!!, I and my friends have been using these for a few years and cant fault it
