I have no shaders/resources on and i cant see the water in fluid tanks and pipes. Is anyone having/solved this issue?

If your using optifine try updating it. Also try turning experimental rendering on/off (/create experimentalRendering on/off)

Also, does it happen with just water or other liquids as well? Can you provide screenshots of his happening?

Ok, lemme try that. Also I will send screen shots. And yes, it happens with all liquids.

Hmm, i tried everything you recommended (including updating my forge) and i still cant see the water, but thank you for helping.

Are you on the 'fabulous' graphics setting? If so, try switching to fancy

I am using "FABULOUS!". ok, i'll try switching

Thank you @simibubi, switching to fancy graphics worked.
