Success with gravel vacuum?

[peterhos]

Good day to all.

Have used the new Eheim battery gravel vacuum 3 times over 3 days for 5 minutes per go.

Po4 dropped from 0.30 to 0.15 (on a second Hanna test after first gave 0.02 reading).

Would be great to think this vacuum cleaner helps in some way.

Encouraging?

I have no doubt that it’s helping! It’s pulling out fish poop, decaying food, etc.
