Hi,
Is the phosphate in a phosphate buffer available to plants? In this case the buffer is waterlifes 6.5 buffer:-

The tank in question (160litres) is going to have floating plants only, 'salvinia' and maybe some 'frogbit' to aid breeding anabantoids and no co2 injection, lighting is less than 1wpg. I'm thinking a small amount of N and K plus traces will be enough, it would be nice to get this confirmed (or not) though.
Regards, Chris.
