    Need experts opinion on my readings

    I have a slight algae bloom going on. My numbers are below.
    Total chlorine 8.8
    FC. 6.8
    PH. 7.4
    ALK. 90
    CH 175
    CYA 45

    Have been advised to use some algaecide, is that the fix?

    No algaecide is not the answer. This is the answer pool-school/shocking_your_pool.
    This process has to be followed to the T.
    Your done SLAMing when
    1 water is crystal clear.
    2 CC of 0.5 or less.
    3 you pass the OCLT. pool-school/overnight_fc_test

    Do you have one of our recommended test kits ? Make sure you do some reading in pool school so you have an understanding of water chemistry and so forth.

    pwrstrk gave you good advice. Algaecides can be insurance to help keep algae from starting (although we generally don't recommend using it for regular pool maintenance on tfp), but once algae gets started then chlorine is much better at killing it.
    TFP Expert who uses Pool School and my TF100 test kit along with PoolMath for my: Round 11K gallon AGP with deep end, 20" sand filter, Matrix 1hp 2spd, 6 2ftX20ft solar panels (and solar cover!), Intex SWCG (copper bars disconnected) and a Rubadub hot tub (chlorine). The SLAM process is not finished until: 1. CC < 0.5 ppm, 2. An OCLT < 1.0 ppm and, 3. The water is crystal clear.
