Review on LONDAFISH Electric Vacuum Cleaner Operated by Stacey Taylor

I have several tanks from 10 to 125 liters. Everyone has their own sub. Or at least distraction. From semi-fine gravel to sand. This device has been tested on all of my tanks to see if it works as advertised or if it can only be used on specific submarines. None of them was the final verdict. I returned it. It took too long to make one of the tanks - I thought. After realizing that it did little but stirred up some surface debris (and in fact it only removed half of the sand's surface at best), I returned with my hand held gravity vacuum and finished the job. I'm not saying this is a crappy product. I say it's not for me.
