Is this a high fish load?

    hi, i have noticed some decline in plants growth recently, the only thing different is the fish load, i have a 75 gallon tank, co2, EI, 2X39 T5, 2X2217 FILTERS:
    20 rummynose
    30 Harlequin Rasbora
    15 cardinal
    4 SAE
    4 OTO
    these fish were added gradually
    is this a high fish load?
    thanks

    Hi hani,

    I would think you are okay as the # of fish.

    I don't think it is the cause of poor plant growth.

    I would say that over time perhaps the balance of c02, nutes, lights, and bio-mass got wacked.

    You need to increase c02 and ferts as bio-mass increases. Have you done this?

    yes, i did increase co2, fert, the only thing makes me think its a fish load is the surface scum witch i never had before despite good surface agitation, filtration.
    any thoughts?

    Certain foods seem to increase surface scum more than others. Bloodworms cause it in my tanks.

    Higher O2 levels help oxidize surface film. With a heavy fish load, organics could overload a biological filter. Add a little H2O2, maybe. Not that any of this would mater to plants. Well, maybe too much hydrogen peroxide. :p
