what is the lighting?
can i point you to ukaps search EI methods .Roma 125 has 2X20W T8 bulbs. So 40 watts in total over a 33 gallon tank =1.2WPG=Low light tank
soz didnt realise it was posted on here just looked after you told me so my advice is have a good read its not as scarey as it 1st sounds if you ignore the chemical names and just look at it as plant food .Paul, there is the same info on this forum, the poster can look in parc for the ei method.
I totally agree, making your own is easy and a lot cheaper. Personally though i liked to get to grips with ferts first, before making my own.
It's up to you Josh, try and gain a little understanding on what the ferts are doing/do and it will come a lot easier.
I am guessing the fert will be for your 125L Roma. Since you are going to go for low light plants, then you might as well get the normal TPN rather than TPN+. TPN+ really shines when used in high tech tanks but why not save your self some pennies and get TPN. TPN works fine in low light tanksAs it will be my first planted tank I am a bit unsure. To start off, I might just use plant nutrition+
what is the stocking going to be like Josh?
if you are lightly stocking, i would still use the TPN+, it never hurts to OD the ferts, just make sure you keep up with the water changes.
Back to the OP, yes making your own mix is very easy, the only thing you need apart from the powders would be a good accurate to 0.01 pair of scales. Measure out each powder to the recipe supplied and add to 500ml of either tap water or RO water.. really doesn't matter which. Mix and make sure all salts have dissolved and there you are a cheap version of TPN+ that will work just as good![]()
