I've read many things but not one thing matches the other, I've read that plants won't grow in tanks under 10 ppm no3, I've read they won't grow in tanks above 20 ppm no3, I've read that some have to have 30 ppm no3, I'm aware for a fish standpoint lower is better, but I'm just curious about the affects on plants growth VS no improved growth at certain ppm in a low tech setup as I don't run co2.
I'd like to be around 15 /20 (including ferts) but that's literally impossible for me to do as I take extremely good care of the tank with water changes, light feeding /thorough gravel Vacs during water changes, filter maintenence every 2-3 weeks, 1 aquaclear 110, 1 aquaclear 70.
Reason I ask is because no matter what I try I cannot get my nitrates to reduce they are about I would say as I'm red dominant 35-45 my nephew says 60, I have a 55 gallon tank 2 larger rainbows boesemani /red Irian, the other 5 rainbows are small species, 2 sentani /2kangaroo creek /1 parva, I also have 6 ornate tetras, 6 lemon tetras, and 1 calico bn.
I dose thrive at 6 ml a week 2 pumps on mon/wed/Fri 50% water change on Sunday
Tap is about 5-8 ppm, (took a Pic but can't find it) light light orange.
I have tried literally everything to reduce the nitrates, increasing water change from 1x a week to 2 times, replacing substrate (old tank syndrome), nitrate removing bagged stuff for the filter, cutting food back to 4 x a week, cutting tap water with ro/di , you name it I've probably tried it, only thing I haven't done is add a pothos roots to the tank or floating nitrate consuming plants.
Any suggestions on how to lower it maybe I've overlooked something and haven't tried everything?
Right now my tank is moderately planted, have 26 plants coming on thursday (10 stems rotala indicia, 10 stems bacopa caroliniana, 4 cryptocoryne spiralis, 2 brownie blue Buce.
in the tank atm I have 18 stems L. repens, 8 stems money wart, 1 Amazon sword, a big amount of anubias, 10 very tall cryptocoryne Wendtii red, a little patch of cryptocoryne parva.
I'm totally new to plants (3 months) so I'm just worried my nitrite levels are to high to effeciently grow plants.
Here's a Pic of what I think is max 45 and a Pic of my tank.
Please don't laugh I'm new, I know the tank isn't up to most people liking but I am at least trying
