I would probably head to the store and buy 5-10 one gallon jugs of RO drinking water, then mix up a smaller batch in a different bucket to see if it still happens. Then you can narrow it down more to the filters\water source. Also, mix up another small batch in the main res with more store...

I came up with a new dehydration tek: Take a metal mesh waste basket (about 5 gallon bucket sized), and add a hatch for the lid (using some hardware cloth and wire for twisty ties, etc), and maybe a few mesh panel sections to act as trays added vertically inside of it, to stack apart the...

I never submerge pumps in reservoirs anymore. Always use inline pumps and install them somewhere outside of the container.. Not only do they create more warm surface area and crevices for pathogens\scum to take hold, but heat up the water twice as much when submerged. Except for when I soak my...

Be careful. Most reports that I've seen about dehydrators going faulty (and possibly starting to melt/smoke.. although rare) are because little chunks of mushrooms/substrate fall or get sucked down in, and get caught up in the heating/fan components inside the units.

Might as well plumb the LRS-600 psu while your at it! ;) https://meanwellpowersupplies.com/the-advantages-of-water-cooled-power-supply/

Pretty sure the rule of thumb is that each 120mm radiator or section is good for around 100w.

The orange fungus stuff probably isn't all that harmful to you or the plant. Just leaching off the salt buildup. It can leave white stuff behind too, but yeah I would probably unwrap it and cut it away. Slice it right off thin like bread. Then get more light and air movement down there. Maybe...

This kind of rectangular aluminum tubing would make the best liquid cooled bar light water blocks, IMO. Cap the ends off, and then drill and tap your holes for plumbing fittings to screw into, one on each end.

Here is an edge cooled water block plate idea I came up with. Should work for COBS, and probably overkill for 15w SILs. Basically, you just cut a flat bar thats1.5, 2" wide, etc) up into as many little sections as you need, and then weld aluminum or copper pipe to the sides of the plates, using...

You can make your own HOCI with a generator, which ends up costing pennies per gallon. They have smaller units that look like a coffee pot now, for around the same price as a gallon of the UC roots snake oil water. Basically you just add water, salt, and a little vinegar, and turn it on and...

I would worry more about flushing it proper with the clearex solution. Before chasing the runoff or really changing anything. Even at the low levels, it keeps accumulating.

Why are you feeding cal/mag too? You already have loads of calcium nitrate using Jacks 321 part B, and should be using epsom's salts for the magnesium. ?? How were you getting 2000 PPM (EC 4.0), when mixing 321 at the proper measurements usually ends up being around 2.0 at full strength? You...

Sure, you might as well try out whatever the main res already has mixed up. Or go ahead and dilute it down some if you need to, in another container. They might handle it as is no problem though, and wouldn't surprise me. Dealing with multiple different reservoirs during different stages is...
