i have some really strange eggs apperaed in my pond this year, they are as describe although i have pictures if anyone thinks they can identify.

my pond is raised off the gorund its 5ft long by 4 ft wide and 22in deep, i have a uv filter (green machine) running.

In the pond i have 3 kio of about 6 - 8 inches, i large lilly and nothing else, water quality is fine and clarity also.

these eggs are ina a quite solid clear jelly the case is about 2inches in length and about 10mm or so in diameter, flatish though as attached, they are stuck (VERY FAST) on the pump head case and on the filter pipe (does not pop if you push on them) eggs id say are about 1- 1.5mm in dia and an opaque peal colour and id say there are around 150 or so eggs in each case i have noticed about 6 or so of these cases can anyone please help??????

Could be 'pond snail eggs'. There are photos online to compare with what you have. Newts and toad also lay their eggs in jelly strings, but the individiual eggs are bigger than you describe. You might not have started with snails but they -and doubtless other water inhabitants- will hitch a ride on any visiting froggy.
