I have just began to filter peat in my 200gal tank. I have not got the recommended amount of peat in the filter as it won't fit
I have some new plants arriving today/tomorrow from Java-plants and I was wondering that if peat is used with all its benefits to plants, do I still need to add fertiliser as well? I don't want to OTT and introduce huge amounts of nitrates to the water. The tank is pretty will stocked as well.
Thanks.
