Is My Dosing Enough?

[Ian H]

Ok just wondering if im dosing enough ferts? Normally i would dose 45ml of TPN a week, but since monday i started dosing 15ml a day of TPN+ at the moment i have 3 nutrafin co2 units on the tank (not enough i know) and 4 x 40W bulbs (T8)with reflectors on 2 of the bulbs.

I have just bought all that is needed for a pressurized co2 set up (FE method) and plan on buying two more reflectors (for the other 2 bulbs)

I'm just wondering if this wil be enough dosing of ferts? ( i have a plain gravel, no ferts in it at all) all my plants are easy/normal that require low to medium light.

So far the plants are looking healthy and no algae outbreak just wondering if im missing anything that TPN+ dosn't dose?

You are dosing enough, i would be tempted to go woth 20ml (i dose 5ml per 100l) especially as yu have inert substrate - you can always adjust that accordingly thoough.

TPN+ is just trace elements, and trace of your macro's, (EI doses more macro's) TPN+ is also quite ow on PO4 but i wouldnt worry to much about that.

Powders might be better as it will be cheaper on a large tank, or you can do a DIY TPN+.
