Wonder Shell (Super Size)

Immune Booster & Water Conditioner

$12.90

Do your fish or shrimp sometimes seem lethargic, lose their appetite, hide, or sometimes die without reason, no matter what you do? It’s often not your fault – it is difficult to replicate the true water quality of nature, with the electrolytes and minerals from a large body of water.

Try the Original Wonder Shells from American Aquarium Products (AAP), and complete the missing piece of your fishkeeping journey.

As avid fishkeepers, we use it in all 12 of our tanks, and the results speak for themselves.

  • Acts like a constant water change as it dissolves, releasing essential trace elements, cations and electrolytes found only in the wild: keeping fish healthy and significantly reducing chance of disease

  • Great for predatory fish, and when introducing any new fish in aquarium

  • Absolutely essential for African cichlids, puffers, livebearers (guppies etc.), goldfish, Flowerhorn, rays, brackish tanks, snails, turtles, crayfish and all shrimps to prevent mineral and GH depletion

  • An added safety net for quarantine and hospital tanks as it purifies water

  • Prevents dreaded PH crashes and “sudden death syndrome” caused by ammonia spikes

  • Proven to reduce oxidative stress by providing a constant electrolyte charge as it dissolves (unlike the sudden effect of dosing supplements/meds in liquid form)

  • Prevent the dreaded cotton mouth disease (columnaris)

  • Replenish lost minerals, and buffers Singapore’s inconsistent GH water

  • One Regular Wonder Shell treats up to 350 Litres.

The equivalent of fresh mountain air for your prized pets - they will be active, colour up and reward you with maximum enjoyment for a long time!

“I've been running my 90 gallon reef tank with lots of softies for about 15 years. The Sea Lab #28 have been the only product that has been able to keep my calcium right at 430. It doesn't move. I put one block in my refugium in an area of medium to low flow and when it dissolves - then replace it with another one. My alk is right where I want it 8 - 9. When I was using the liquid chemicals and trying to dose manually (before that) - I've never purchased an auto-doser, I was always chasing my calcium levels.....too low, then back up, then too low, etc… I'm very happy that I found it because it works for me. I've never seen spikes with either Alk or Calcium. They stay right where I want them. When the block is almost gone I replace it with a new one. I'm just about to order another box. I found this stuff about 2 years ago and it has really made my life much easier for keeping my ALK and CA right where I want them. You're mileage may vary, but I'm ordering my 5th or 6th box and will continue to order.” – smcdonald
