Dosing Daily over Dosing Weekly???


So plant's like a stable environment, correct? Then why don't we dose daily so our plants get the exact same amount of nutrients each day rather than dosing weekly and helping algae grow?

I understand if you dose 1/8th tsp or less of KNO3, KH2PO4, etc. it would be extremely hard to divide that by 7 but could you mix the small dosing with water? For example add 1/8th of a tsp of nutrients to 7ml so you dose 1ml each day?

I do dose daily instead of weekly and so far it seems to work well for me in keeping away algae. I'm currently in the process of switching over from Seachem Flourish Fertilizers to the PPS-Pro Fertilizer mixes, which means that I do mix dry ferts with distilled water and then dose 0.1 ml per gallon or 1 ml per 10 gallon daily.

For dry fertilizers I'd use a gram measuring scale, you can get very decent ones these days that measure out to 0.01g increments and up to 100g for around 10 US Dollars on Amazon.

PS. Also shouldn't this go in water parameters and fertilizers rather than lighting?

I could of sworn I put this in Parameters and Fert's, lol.

So what ratio of fert to water would be recommended? the 1/8th of tsp to 7ml of water?

And then dose 1 ml a day? Yea that should work, just remember to use distilled water or some type of water that doesn't contain chlorine in it.

So water treated with prime would work, right?

that is what i do. i use liquid ferts and i have the macros in a bottle then i dose a specified amount daily. I have a spreadsheet from seachem that i altered for my tank specifically. i add like 1ml a day, then carbon on top. I don't know if it is better, but i have a routine. When i get home, i check water parameters, temp and then water change as needed, then i add ferts and then i feed.. makes sure that i don't miss anything.

We do. Well, I do. Macros at 10:00, micros at 23:00.

Keep in mind though that the exact level of a given nutrient is not that important, as long as there is some available, and it is not in total excess where it starts to throw other things off.

For example, it probably won't matter if your NO3 levels are at 10 or 20 ppm. But, if you have a high tech tank, it might eat more that than in a week, and that is where you need to go to a more frequent dosing schedule.

So currently I dose:

Sunday: KNO3: 1/8th teaspoon + KH2PO4: a smidge, about the size of a BB + Traces(CMS+B) 1.5ml + Excel 1ml
Monday: Traces(CMS+B) 1.5ml
Tuesday: Traces(CMS+B) 1.5ml + Excel 1ml
Wednesday:KNO3: 1/8th teaspoon + KH2PO4: a smidge, about the size of a BB +Traces(CMS+B) 1.5ml + Excel 1ml
Thursday: Traces(CMS+B) 1.5ml + Excel 1ml
Friday: Traces(CMS+B) 1.5ml + Excel 1ml
Saturday: PWC + Traces(CMS+B) 1.5ml + Excel 1ml

What type of ratio of KNO3 to water and and KH2PO4 to water would you recommend? It's a medium planted 10g with 2 x 13watt 6500k CFL's.

Honestly I'd hesitate to use Prime treated water, they say on their site that bound chlorine and ammonia start to unbind after 48 hours so you would need to add new prime to your fertilizer water every two days to be certain...of course by then if you have chlorine and not chloramide it should be safe I believe.

I have chloramide treated tap water here so I don't use it for anything but water changes and then I always test my water for ammonia on the second day after a water change. If it still has ammonia in it (a byproduct from treating the chloramide) I put in another dose of Prime.

I dose 2-3x a week for my own tanks.

Clearly, they have no issues even with the most fussy plants that are possibly available in the hobby. Could I go a whole week? Well, perhaps for some, others, not likely.

Daily does not hurt though.
But there's no significant differences with daily vs 2-3x a week.
Perhaps dosing traces daily might have some slight effect, but not macros.
And there's no issues with algae for either case.

I'd not bother with ratios.

I dose about 3:1 by mass NO3: PO4.
15 ppm and 5 ppm dosed 2-3x a week.

I'm still learning the fert language, lol.

What do you mean by 15ppm and 5ppm?

"ppm" refers to parts per million, a unit of measurement for concentration. An equivalent unit of measure is mg/L (milligrams per litre).

So how would you figure out the ratio of KNO3, KH2PO4, etc. to water?

Ideally, you would measure out each chemical to be dosed, and calculate the increase in concentration when it is diluted (dosed) into your aquarium.

There are various calculators that can be found (linked on these forums) that will do the calculations for you.
