    Hey guys. :)
    Just a simple question.
    I change my tank water 25% on wednesday or thursday and another 25% on saturday. But I only dose ferts on saturday.
    If I do water changes like this would this basically be the same thing as doing a 50% every saturday?

    Thanks in advance.

    You would be better off dosing after every water change, what you doing is not going to help the tank a great deal during the week, specially when you taking some stuff out and not putting anything back in ;)
    After every water change dose your ferts, that would make for a much healthier tank ;)

    Cool, Thanks London Dragon. :D
    I'm not sure if I am dosing things quite correctly though.
    I dose 2 pumps of ADA green brighty step 2, 2 pumps of green brighty special lights, and 5 ml of tropica plant nutrition+. Would it be ok if I dosed like this every 25% water change 2 times per week?
    The tank is around 43 gallons. I'll be sure to get a accurate measure when I have time.
    My plants don't show any sort or nutrition defiencies, but there is quite a lot of staghorn algae growing on the glossos.
    BTW, the plants in the tank are glossos, 3 fist sized blyxas, some moss on bogwood and some sort of ludwigia.
    I'll try to post pictures.

    Once again, THank you so much in advance.

    So thats about 180 liter tank, what kind of lighting do you have? pressurized CO2?
    I have never used ADA ferts so I wouldn't know their dosages, but TPN+ is an all in one solution that has almost everything you need. Dosing 5ml once a week does seem very low, thats more like a daily dose amount and for your tank size even then would seem on the low side, how long have you had this tank up and running?

    Yes, there is co2 injection in the tank. The lighting is 55x2.
    The tank has been running for about,,,,,uhhh,,around 4-5 months.
    Wow, TPN+ 5ml per day seems quite a lot. Compared to what I usually dose (5ml per week).
    Maybe, I should start dosing 5ml every other day and then start dosing everyday. Cuz it feels like a big jump.

    Do you use a drop checker to measure CO2 levels?

    110w is a lot of light specially if you injecting CO2 too, algae will be the result if the plants don't get enough ferts.
    Also flow in the tank is important.

    No, I do not use a drop checker.
    I'm pretty sure I have enough surface agitation because I use a spray bar that is almost as the tank width.
    I'm not sure about the flow in the tank, but its strong enough to bend the blyxa leaves.
    Algae will appear when the plants do not get enough ferts?
    BTW, can you give me some tips on how to prune blyxas?
    I tried cutting the leaves about an inch from where they start out but its been like 2 weeks and they dont seem to grow back.


    Thanks in ADvance.
