    That's the main reason I don't use heaters much.:D

    I'm not sure why, but I've never done well with Rainbows... They just don't seem to like my tap water.

    Hi,
    My small Test tank is a 12L Nano (around 3Gal) und has 2x13W lightning.
    (The tank isnt a scape, it is just a "plant mix" without any logical order :D)
    Substrate is ADA Aquasoil, I started the tank with bacterial pond boosters. (AquaDry5) and full lighning + full fert dosing. Doing so hasn´t result in any problems. Everything stayed crystal clean and there were never any algaes like GDA, GSA or so showing up.
    I am not sure, but I guess those algaes dislike low KH or PH
    (Tank KH is 0 and PH around 4,5-5,5)

    Well, meanwhile I maked one 25% waterchange, because I noticed that some plants slowed down their grow rate a little bit.
    This was the only thing that happens
    (after a 4 month period without doing any waterchanges)

    I switched over to this method and it has been working well enough for past 4 months.
    Dropped dosing a bit and switched to wc every 15 days, no problem apparent so far.

    I do not think there's any evidence of risk really.
    I just like doing water changes and having my plants grow and have the tanks look clean.

    Since I have to use a hose to top off anyway, why not drain it down 50 % first? I suck out mulm in the process. It is, an easier way for me to clean things up.

    My view as well, some find other excuses or reasons why it's bad.
    Thge same advice can be extended to Reef tanks, but the cost of salt mix can set you back some $, but vs 300$ electric bills, Skimmers and what not, the automation and potential FOR THINGS GOING WRONG. It might be a much wiser idea, many nano reef folks do this.

    My small test tank is meanwhile 10 month old without doing new water changes.
    The plant grow is always the same, the plants are bubbling the whole day and need to be trimmed weekly.
    There were never any algaes showing up. Just the water surface has sometimes a thin metalic looking layer. I guess it has something too do with the iron if never doing wc?:confused:
    Other problems never showed up, the EI dosing seems to work also for long period without doing WC.
    I used liquied fertilizer (Vimi All-In-One)

    I've neglected tanks for long time frames without issues also.
    thicker higher plant biomass seemed to help also.

    Had you also after several month a surface layer?
    It happens after fert dosing.
    Can such a surface layer be removed by any biologic or bacterial add ons?

    if the surface scum can be breaked with the finger, you can put some surface plants to deal with it, but be careful not to overcome the light for the other plants
