Do you need an inriched substrate?

Hi everyone,

New to the forum and wondering if I have already made a mistake, last month I set up my RIO 240 with the intention of it being a planted discus tank, I bought a 1400l per hour external with a uv light from all pond solutions and it's been cycling since. However the tank came with some silver silica sand and I opted to use this now I am wondering if I have messed up by not adding any inriched base substrate? I have a 48" discus collection of plants ordered from plants alive that should be here this week. Also I have jbl aquarium peat ordered to naturally lower ph, I hope it doesn't cloud up the water too much but I replaced the standard media with seachem matrix and purigen?

P.S. will cabomba grow without CO2?

Plants are plants whether you grow the in water or not, meaning they need nutrients to live. I would look for some root tabs and look for some ferts for your water column. Plants like dirt and there are several manufactured substrates designed specifically for planted tanks. The JBL peat might leach some tannins into your water making it brown but it will clear with a few 50% water changes. As for the Cabomba, its considered an easy plant to grow and will do fine w/o Co2.

Your purigen should absorb any tannins, but as stated above, keep up with the water changes. That stuff works magic for tea water. And the cabomba. There's a reason it's labeled as an invasive species in most states. It has been recorded to grow 2" PER DAY in the wild. Mine grows in a 29 gallon tank about an inch per day under a single T8......with no C02 or ferts. By the way, the stuff is impossible to kill. Otherwise beautiful plant.

Thanks for the advice guys my plants arrived today and they are all looking pretty good in the tank, I also got root tabs to try get some nutrients for the root systems so now it's just about waiting and hopefully they will settle, will add some pics soon.

Thanks again
