I have Walt Smith's Fiji mud in my sump and I feel it helps.
Interesting, definitely something I'll be looking into I've had a few friends advise to give it a go.
Great build, following along
Glad to see you're enjoying the ride,
R.O production is still in full swing.
We also nipped out to a local DIY store and got a few small bits, firstly we got some stickback M3 tape and stuck one of my web cams to the sump door allowing me to see the state of the skimmer / sump / ATO / XR15 light etc
We also grabbed some 13mm square rubber..stoppers?? feet / furniture protectors which We're using to act as stoppers preventing the ATO from hitting the return pipe, its a simple addition which just generally helps with the running of the sump.
I intend to stick something like a fluorescent ping pong ball / fishing float / other floating object in the ATO so it makes it easier to see via the webcam how low the water volume is.
(ignore the wires at the front those are temporary heater cables.)
