England's Benjamin Proud beat Australia's Cameron McEvoy and James Magnussen to the gold medal in the men's 50m freestyle final, while New Zealand's Lauren Boyle took the glory in the women's 400m freestyle.
Boyle beat Jazz Carlin into second place, a day after the Welsh swimmer's triumph in the women's 800m freestyle gold.
But Georgia Davies gave Wales fresh reason to cheer by prevailing in the 50m backstroke in a Commonwealth record time of 27.56 seconds, becoming only the third Welsh woman to win Commonwealth Games gold in the pool.
Daniel Tranter got Australia back on track in the men's 200m individual medley, however, seeing off Scotland's 400m individual medley champion Dan Wallace and South Africa's Chad Le Clos in a Games-record time of 1min 57.83sec.
Australia were expecting further success in the relays later on Tuesday.
The Australians were fastest in the morning session in both the men's and the women's 4x100m medley relays, having previously taken gold in the men's and women's 4x100m and 4x200m freestyle relays.
However, South Africa were expected to challenge for top spot in the men's event with butterfly specialist Le Clos to come into the team that qualified fifth fastest.
The doping case involved Nigerian weightlifter Chika Amalaha, who was provisionally suspended from the Games after testing positive in a drugs test taken after she won gold in the women's 53kg category.
The 16-year-old provided an 'A' sample on July 25 that revealed traces of diuretics and masking agents, the Commonwealth Games Federation announced. She will have a 'B' sample tested at a laboratory in London on July 30.
In the athletics, Joyce Chepkiri produced a late burst to pip Kenyan compatriot Florence Kiplagat to glory in a gripping 10,000 metres, with Emily Chebet completing a Kenyan sweep of the podium.
Olympic champion and world record-holder David Rudisha of Kenya cruised into the semifinals of the men's 800m after safely negotiating his heat.
"Today was all about qualifying for the second round tomorrow," said Rudisha, whose staggering 800m run in just shy of 101 seconds was the stand-out performance on the track at the 2012 London Olympics.
Earlier on the track, the men's 110m hurdles was blown wide open when England's defending champion Andy Turner pulled up and Jamaica's Olympic bronze medallist Hansle Parchment was a non-starter.
With Parchment failing to even make it to the start line, the field has now been opened up.
Jamaica's Andrew Riley, Barbadian 2009 world champion Ryan Brathwaite and England's William Sharman will all fancy their chances in the final at Hampden Park later on Tuesday.
The women's 400m, meanwhile, features defending champion Amantle Montsho of Botswana, also the 2011 world champion, and in-form Jamaican Novlene Williams-Mills, who has racked up three Diamond League wins this season.
England's male and female gymnasts completed a clean sleep in the team competitions.
England's five-man male team of Sam Oldham, Louis Smith, Kristian Thomas, Max Whitlock and Nile Wilson scored a total of 266.804 to take gold at the Hydro.
Their success came despite Oldham having to drop out after sustaining a suspected dislocated ankle on the vault at the start of day two.
"We've been preparing for this for a long time and for it to go well on the day in front of a crowd like this is amazing," said two-time Olympic bronze medallist Whitlock.
Scotland's men claimed their first ever Commonwealth Games team gymnastics medal by coming second with a score of 257.603, while Canada took bronze.
The English women, inspired by 16-year-old Claudia Fragapane, matched their male counterparts by seeing off Australia and Wales to claim gold with a total of 167.555.
There were early gold medals for Canada's Catharine Prendrel in the women's mountain bikes and Anton Cooper of New Zealand in the men's equivalent.
David Chapman in the men's 25m rapid fire pistol and Adam Vella in the trap brought two more shooting golds for Australia.
Jen McIntosh claimed silver for Scotland in the women's 50 metres rifle three positions, enabling the host nation to break their record for medals won at a Commonwealth Games by lifting their overall tally to 34.
