Reply With QuoteMyself, I think the effectiveness of iron is difficult to tell. I am dosing a little seachem iron once a week. Seachem Potassium is definitely good, but expensive. Read the label carefully, it is just diluted K2SO4 in liquid form.
hi bro, thinking of switching to above from k2so4 powder and ada eca. Any feedback if they ard good or any brands to recommend?

thanks bro barmby, did not know its k2so4 in liquid form. But i think they are quite cheap compared to ada brighty k and eca.
Btw, I'm using Tropica fertiliser but i noticed more bubbling with addition of potassium, so i think have to add them as a routine.. Too bad ADA brighty K is so costly or this would be my first choice.
Just an update that after using seachem potassium and iron for a while that they are quite effective. Also, according to the label, seachem potassium is made up of K and O and does not have S - sulphur.
hi o2bubble, it is k2so4, because i found it on the label of the seachem bottle.

My interest has wandered! Do U?
Seachem Potassium, the label said is derived from Potassium Sulfate.

I read the label carefully and it mentioned it contains K2O which is derived from potassium sulphate. I assume there is no S contained? Anyway, I did not notice any shrimps dying after using it instead of potassium sulphate powder.
Guys, don't confuse me. heh..
Potassium sulfate (K2SO4) (in British English potassium sulphate, also called sulphate of potash, arcanite, or archaically known as potash of sulfur) is a non-flammable white crystalline salt which is soluble in water. The chemical is commonly used in fertilizers, providing both potassium and sulfur.... from Wikipedia

Guaranteed Analysis
Soluble Potassium (K2O)05.8%
Derived from: Potassium Sulfate
Elemental potassium is present at a concentration of 50,000 ppm (e.g 5%). Archaic fertilizer laws require us to list potassium in terms of equivalence to a material that is not present (K2O) rather than the more scientificaly sound method of simple elemental equivalence.
Bubble,
Basically K2O (aka Seachem Potassium) is at 6%, it does say 0 - 0 - 5.8 on the bottle itself. Application is 1 capful or 5ml for every 125L or 30 US Gallons. From personal experience, if you need to dose these, get the 500ml ones as the 250ml can run out pretty quickly. =)
Seachem Iron is quite concentrated, some might even call it potent, too much of these will invite algae to "knock knock", smile at you and start to populate itself in the tank. If you want to get one, you can. But I also recommend you to get one those disposable needles (syringes) from Guardian at Admiralty MRT, try the dosage at 1ml o 2ml first. Observe for 2-3 weeks, before you decide to increase the dosage. 250ml is pretty sufficient.

bro bluewhale. thanks for the great advise! Now I know why I'm getting hair algae recently! I have been dosing 15ml of SeaChem Iron twice every week for my 300l tank! But this is roughly accordingly to the dosage but may also be high due to iron already contained in tropica fertiliser I'm using.. Will reduce to 5 ml twice and observe. As for seachem potassium, I'm dosing 15ml twice every week and looking fine for now.
Hee Hee...Plenty of light + Iron you get boom boom =), congrates! You just made it to Algae farmer, heh heh...
Basically I think once a week is sufficient. Usually I dose 1-2ml during water change. So you see I ain't dosing that much either. But it still boils down to what kinda soil you have currently. I am using Ada Amazonia II combined with two other types of black soils. Now if you do not know the properties of the soil, you'd have to test them. I have a thread on my setup, you can read it if you want to.

Thanks bro, I'm using ada amazonia II as well, with Tropica fertiliser, ADA green gain, Seachem iron and potassium, Dennerle S7 dosing twice per week. Think I added a bit too much of iron with minor hair algae invade now
Hmm..didn't you read other threads that Thio (Biotope) posted? Amazonia II and Amazonia do not need to add substrate. So if you are using pure ADA Amazonia soil, actually you do not need to dose. Okay, if you die die must add, then add 1-2ml, use the syringe to measure.
So what if you don't add now, won't the seachem be wasted?
Well the substrate would be expended one year down the road, that is when your chemical warfare will commence. =)
before dosing iron, my red plants was not so red. So, I believe a little iron helps. Will reduce the dosage and see how..
Tanks differs from one another due to setup and size. I think you just need to moderate the amount that's all. =) Do plenty of observation. I share with you how I do it. Because my eyes are not sensitive to pickup all the information and store it in the brain over a period of time, I just take pictures with my camera phone at different time interval. When it is time to review I will compare the pictures to see what is the differences, before and after. =) Hope this helps.
Good advise but problem is i only have normal 5mb pixel camera. Cant get good photo. Getting a dslr one soon.
