  Inclusive KsKs production in deep inelastic ep scattering at HERA has been
studied with the ZEUS detector using an integrated luminosity of 120 pb-1. Two
states are observed at masses of 1537{+9}{-8} MeV and 1726{+-7} MeV, as well as
an enhancement around 1300 MeV. The state at 1537 MeV is consistent with the
well established f'2(1525). The state at 1726 MeV may be the glueball candidate
f0(1710). However, it's width of 38{+20}{-14} MeV is narrower than 125{+-10}
MeV observed by previous experiments for the f0(1710).
