Mine are for sale. Make me an offer ? https://www.ukaps.org/forum/threads/ei-liquid-carbon-peristaltic-dosing-pumps.74232/post-749277

I did once use a short length of blue silicone air tube to connect my CO2 in tank diffuser from bubble counter. After not very long the tube just went hard and brittle (especially the bit in the water), unlike the proper CO2 tubing. CO2 will diffuse through/into silicone apparently, though I...

There have been experiments done using carbon 13 versions of glutaraldehyde based compounds and mass spectrometer of plant material reveals it contains carbon 13. Not sure if quantities taken up are meaningful but there is some science behind liquid carbon. The Seachem versions of liquid...

Try something like Seachem Clarity and putting a sheet of fine floss in the filter for a day or two. I have used this many times after a major plant re-arrange and water went cloudy, the floss after a day or two was covered in a fine slime !!!!

Should use silicone oil on the seals, not petroleum based products, Vaseline etc as this will degrade the seals. I used push fit plumbing silicone oil from Wickes.

I cut my Juwel lighting unit open after it stopped working. Reason was it had water in it after previous owner had left one end in water. I got it open, got it dried out and it worked again. However I was never able to 100% reseal it again, as the original units are plastic welded shut. Best I...

You really ought to have a 3rd empty (or little bit of water) catch bottle before the tank just incase bottle A or B overflows. Any of bottle A or B entering the tank will kill all in the tank.

Should be fine. My tank & filters went for a couple of days, one winter, after a sub station neutral fault tripped the RCD in the house, whilst I was away. Another reason I use a PLC to control the tank . I made the display flash red when the filter and heater are off, after having done exactly...

My surface scum only appeared for a couple of weeks when the tank setup was "new". Removed by floating a sheet of kitchen towel on the surface, when necessary, to pick up the scum. Best removal was an air curtain at the back of the tank, running after the CO2 had turned off, for an hour or two.

You cant use a solenoid with this type of setup as when the solenoid is off the pressure will continuously build up and either burst or leak the system. What you do is use the solenoid to vent the bottles ie solenoid on a night letting pressure out the system. You just have to cope with yeasty...

Some of the "marine boys" batch dechlorinate their water. Something like this (taken from my PLC project). It can actually be a bit simpler. Fill water container with HMA filtered water. Use a peristaltic pump to dose the water with Seachem Prime. Dose sufficient Prime assuming chloramine...

Or you have a leak on your piping after the meter. Turn stop cock off in house and see if meter is still moving.
