Helping

After setting up the dining room yesterday, today it was time to clean the tank, at least to give the gravel a vacuuming. 
 
Mrs W normally does this job (it came with the aquarium!!), but she had to come off her RA meds for five weeks before having a tooth out last week and is in quite a lot of pain, so yours truly filled the gap.
 
The plecs wanted to be useful, and gave me quite a lot of help.
 
Can I use this again tomorrow?
