“Been using instant ocean for just over a year - no issues at all, vat needs a rinse once a month doing a 50 litre water change but no worse than using a certain Red brand product for a higher price , icp’s come back fine , some trace elements are lower but I have to dose traces anyway as a heavily stocked coral tank.”
“I have used Instant Ocean years ago and I believe it’s still one of the best now.
And excellent service once again from Charterhouse……..very highly recommended”
