Just a quick question... Im ordering seachem flourish for the first time, seeing as my LFS has been unable to get my old liquid fert for some time now. I was just going to get the mega jug (2 liters) but it says that it needs to be refrigerated. Does anyone actually do this?
does anyone know how it works without refrigerating it?
if thats the case I might just stick with my old stuff which I THINK its nutrafin plant-gro (not 100% though). Opinions appreciated :-)
I refrigerate it but not sure if it is completely necessary , and I would recommend a smaller size if you have to and not get the old plant fert.
I refrigerate mine also but I think I saw a post awhile back stating it wasn't necessary but can't remember for sure.
I remember seeing that post also. Someone actually emailed them and while I dont' completely remember the response was just like the label they "recommend" it but said it is fine without it. Me personally I refrigerate mine, they must of "recommeded" it for a reason, unless they just wanted to sit back and laugh while watching people put it in there fridge lol
I'm with kangy on this. I keep my jug in the wine fridge which is not as cold as the refrigerator, though I doubt that matters, just my preference. And yes, Seachem did tell us that it didn't matter, but like kangy I would wonder why they recommend it if it doesn't. My initial jug I did not, and I did notice it was "different" by the time i came to the bottom, in fact I threw it out and bought a new one, and have refrigerated since then. The subsequent jugs have not "changed."
On the size, it is considerably cheaper by the 2 liter jug, and it has no apparent shelf life. I can get the jug online for $31 whereas the 500ml bottle is $10 which would mean $40 for 2 liters in the smaller bottles; these prices are Canadian, from an online retailer, so you may get better deals in the US. However, if you have only one tank, you will obviously use much less than I do with 7 tanks (totalling 350 gallons) dosed twice a week so the cost is spread out more.
Well, I have 5 tanks totaling 215g, but i think im only going to dose my 20 long and my 55. The downside, is it isnt available locally ANYWHERE. The other crappy thing is I dont have a fridge on the same floor as the fish room, so I gotta hike 2x a week. But seeing as petco cant figure out how to keep something as simple and common as nutrafin plant-gro in stock (and it doses waaay less than an equal amount of flourish) I guess ill be making the switch.
Thanks for the input folks :)
I literally just opened my Dr. Foster's and Smith order and I got a 2 liter of Flourish. I will be putting that one in the fridge and put a small about in the smaller bottle which won't be in the fridge. It will be in the office where the tanks are.
Flourish Comprehensive is, as the name suggests, complete. The only nutrients missing are hydrogen [water], oxygen and carbon, and these three naturally occur in the aquarium. Brightwell Aquatics in the YUK make a very similar [going from the ingredients and percentages] product but it is more expensive.
As for dose, I believe Nutrafin takes much more than Flourish Comp. I did find that Nutrafin say 1 teaspoon for 10 gallons. Flourish Comp is one teaspoon for 30 gallons once a week. So Plant-Gro uses 3 times the product compared to Flourish Comp.
from the petsmart website re: nutrafin plant-gro
Total Nitrogen (N) - 0.15% [0.15% Water Soluble Nitrogen - Chelating Agent]
Boron (B) - 0.0005%
Copper (Cu) - 0.0005% [0.0005% Chelated Copper (Cu)]
Iron (Fe) - 0.26% [0.26% Chelated Iron (Fe)]
Manganese (Mn) - 0.05% [0.05% Chelated Manganese (Mn)]
Molybdenum (Mo) - 0.0007%
Zinc (Zn) - 0.003% [0.003% Chelated Zinc (Zn)]
so its similar, even in percentages, however it lacks potash, calcium, magnesium, sulfer, chlorine, cobalt, and sodium. Similar, not as complete. The only lure to it was it readily available without having to order online, but now that thats gone by the way side, time to do the job right.
the dosing of flourish (in comparable terms) is 5ml for 60 gallons, while nutrafin plant gro is 5ml for 10 gallons! The hagen website is just awful as far as actual product information. I will evaluate the plants growth and aesthetics over time, and if need be test for individual nutrients, but we will burn that bridge later :-)
The macro-nutrients (calcium, carbon, hydrogen, magnesium, nitrogen, oxygen, phosphorus, potassium and sulphur) are perhaps even more critical, and these occur in tap water (depending upon the hardness) and fish food (primarily when it becomes organic waste in the substrate). Most of these macros are also in Flourish.
Testing for individual nutrients is usually pointless, and some cannot be tested without scientific equipment. Appearance is the best guide. And knowing your tap water hardness, plus the fish load (the food). But symptoms of several deficiencies or excesses can be identical. Which is why most sources recommend a comprehensive dosing (if anything) of macros and trace. An excess of some trace minerals can be serious, as some of them (iron, copper, zinc, nickel, manganese) are highly toxic heavy metals. Plants can take these up in varying degrees and detoxify them, but one doesn't want to push the plant's capacity for this beyond reason. Which is why using a basic trace product, or a comprehensive, will almost always work. Everything is being provided but nothing is in excess. I have in the past dosed a few individual nutrients, with disastrous results, so I agree with those who suggest refraining.
