I beat profile substrate
At first when i switched from gravel/laterite to profile and gravel I had didn't have all my ferts. I was missing NO3, PO4, traces, andpottasium.... At first since upgradign from 110 watt to 20 it was great bu then the nutrients hit a brick wall
at 3.5 wpg in a 75 i got algae BAD. I ordered traces and phourus(sp?) because i figured it would help(stupididity) so i dosed PO4 into the tank wihtout any amount of pottasium. PO4 got high.
Also profile made my KH jump all over... normal here is 8
at the end of the week it would be 4 and 3 days after a water change it would be 4. bu for the fist few after a wc it was 6.
I bought NO3 2 weeks after the switch of substrates it helped at first. last water change i dosed potassium
Well after 4 weeks of floating plants(light substrate) varring KH, high PO4 my plants are growing VERY well. pearling like mad, and look GREAT.
Now my PO4 is .25 untill i dose it to 1ppm and my KH is steady at 7.
Now that my plants are growing well i have enough plant to really stick them deep into the substrate so they actaully stay there... I put to much profile in and not enough gravel. about 85 %profile 15% gravel.
I have the profile aquatic soil i got it from walmart for 3 bucks for 10 lbs on sale. and washed it a lot with a little water changer i though up so i did no work and it didn't cloud my water bad at all.
O and another mixtake i did was buy liquid ferts.. I'm putign in 120 ml of pottasium for 75 gallons... didn't read abotu dry ferts
Profile can work
