I have high hopes for this device.

Will send out the first Fauna Marin ICP on Friday, since I bought it, to determine how closely it matches my salinity readings. The moment of truth. MTC.

It feels very premium, and despite my poor eyesight, I can easily read the readings.

480 USD for an MP40 (https://premiumaquatics.com/product...2&_sid=a07ae45ff&_ss=r&variant=47329565933810).

I have/had two running on the back of the tank, frankly, only ‘for fun’ since the gyres do the heavy lifting.

I bought them when the tank was set up in late 2023.

The left dry side started making a very loud noise a couple of days ago, which was super annoying, so I removed both of them now.

What a waste of money.

I also spent quite a lot of money on various wet-side cages - a waste of even more money.

RIP MP40 - unsubscribe Ecotech continues. Versas are the last one standing.

You can change the bearings in them. Or don’t run them over 75%. Should reduce noise. Let me know if you need help. There’s YouTube videos on it.

Thank you. I might look into this. What I fogot to mention is that these never run higher than 50%.

Yes, hard to read and unfortunately not as accurate as it was often stated.

How did you figure out the lack of accuracy?
I’ll have to make sure I keep the reading next time I ship off an ICP sample

Did they get dropped ever? They're pretty fragile unfortunately. Also they often need to be broken in when first bought which isn't super clear in their instructions. Try swapping the wetsides too and see if the noise improves.

thanks for sharing your MP40s review @Alexander1312 .. I was always on the fence, but guess for now I will stick with gyres.. specially coz I dont have enough space at the back and don't want to put them on the sides with wires and dry side.. wish I did some research and left some more space at the back, cleaning the back wall is a task for me now!
