Fert and gravel ratio

[aqua_not]

Would one bag of Jbl fert and a bag of 10kg gravel (normal lapis) be enough for a 28x18x18 tank? Or should more gravel be added? I heard of fert leaking due to insufficient gravel thickness and causing problems. Anyone care to advice?

I think it's an inch worth of fert added to an inch worth of gravel, topped off with another 2-3 inches of un-mixed gravel. Someone, anyone, correct me if I'm wrong.

I would rather you use the lapis gravel alone (less messy when you uproot plants) or better use ADA aquasoil/Flourite/Onxy sand.

28x18x18 in centimetres, metres, feet, donkeys, or papayas?

Alamak sorry Bro. Tank measurement in inches. Always forget about that. Thousand apologies

you can put as much base fertilizer as you want. top with 1.5"-2" of gravel to prevent the base fertilizer from leaking into the water column. do note that thicker substrate will reduce "available height" for plants.

If it's in inches, yea the gravel amount you have is fine. Half a bag of JBL Aquabasis fert is enough for a 2ft standard tank already.

I also do the same as Thomas. Usually I do 2" base fert and 1" gravel.
If there's deep rooted plants, I increase the height at those areas.
