Shipping Please check the shipping address listed in your paypal transaction as you check out! If that address is wrong contact me ASAP since I pack and ship orders quickly and I do it based on the address paypal gives me. I prefer you have a confirmed paypal address since unconfirmed addresses mean I need to confirm the shipping address with you (this takes time and can delay shipping.) If you get an e-mail from me with a subject like Re: Payment received from your e-mail@your e-mail.com it is me trying to confirm something about your order before I can ship, please open it and respond if you want your order shipped asap.
I do not earn money on the shipping. The paypal calculator is not very flexible so if it over charges you for shipping, I will refund the difference. There is a place on paypal where you can add instructions about shipping (for instance if the shipping address is a business address according to UPS/Fed Ex it might allow me to save you money on shipping for certain products if I know about it, otherwise I have to assume residential shipping. If you add your phone number there I can use your phone number if I ship via Fed Ex for certain products and they can call you if there is an issue with delivery.)
If Paypal doesn't charge you for shipping, it is probably because you are in another country or someplace I don't normally ship to, I will be contacting you about it since I will need to find out the shipping costs to your location and send you an invoice for the shipping or refund your order if I can not ship to you or if you don't want to pay the shipping. I normally Sell in the USA but have occasionally shipped packages internationally.
Plants and Fish I only sell in Florida at this time and I am not set up to ship fish yet.
Return and Refund Policy I try very hard to quickly answer questions about products before the sale. If you are uncertain about a product please ask, I want to make sure that what you buy is what you need and what will actually work for you.
If you buy a product and change your mind about it later and want to return it, I will have to charge a re-stocking fee and I can only accept returns on unused items. I can only make refunds for 60 days after the purchase through paypal. I do not refund the shipping or pay return shipping unless the reason for the return is on my end.
Please contact me for instructions before returning anything. If I'm not expecting something to come back, I won't know what to do with it if it actually makes it to me. Some packages are shipped direct from the manufacturer and simply mailing something back to them won't get you a refund.
If there is a problem with a product, please contact me so we can work something out. Some items are covered by warranty.

Chelated Iron
 Sprint 330 Chelated Iron |

Sprint 330
10% DPTA chelated Iron. |
|
|
One teaspoon per 100 gallons to bring Iron levels up to 2.5 ppm
This chelated iron is better for plants than the EDTA that is more commonly used. |

| This Sprint 330 10% DPTA chelated Iron is what I have been using in my aquaponics systems for the past several years. I have regularly dealt with source water high in calcium carbonate that keeps my system pH elevated and causes my plants to suffer Iron deficiency if I am not supplementing with a form of Iron that remains plant usable at a pH of around 7.6. I do not advocate simply adding Iron all the time. Pay attention to your plants and learn the difference between deficiencies. Iron deficiency shows as new leaves yellowing but with the veins staying green at least at first. If in doubt there are iron test kits available. An Iron level between 2-3 ppm is all you really need and some source waters may be high enough in iron to provide plenty when combined with a good fish feed and a system pH between 6.5 and 7.0. |

Hi!
do you think it should be used or not in Commercial aquaponic ?
This particular product, No I wouldn’t use it in aquaponic water and I don’t think it is the appropriate product for commercial production.
Chelated Iron in General, Yes it will need to be used when it is needed in commercial production.
Can you recommend a specific iron to use with a ph of 7.8? I used an EDDHA by Miller and it turned my 800 gallon system red!!
Thankyou in advance.
How much did you use?
Iron supplements are likely to cause some tinting of the water in a system. The DPTA Iron I use tends to turn the water a bit orange or amber.
Slighting tinting the water is not problem at all but you don’t want to be too extreme in your dosing. If you are running a commercial system you may want to get an iron test kit so you can monitor your Iron levels so you are not over dosing. Iron levels of 2-3 ppm are generally sufficient.
To whom it may concern,
Please help me understand which iron product can be used in my aquaponics tank/garden. Above it appears that you state that you use this 330 in your aquaponics system, but in the comments above it is stated not to use it in an aquaponics tank? Please explain.

there are two different products listed on the page. The sprint 330 I do use in my aquaponic systems. The other product has other nutrients (like copper and zinc) in it that I am not comfortable using in aquaponics unless I am able to accurately measure their levels to make sure they don’t become toxic to the fish.
