lf easiest cheapest way to fert low tech
From what I've read on other posts, and info I have received on some other questions I'm probably gonna get hate mail for this lol but I have to ask.
Tank details: 3 , 23 watt Cfl 6500k bulbs in reflectors sitting 15inches off substrate which is sand in a 29 gallon. I have about 3 inches of sand. I have good water movement, using an powerhead and a fungal 305 canister filter with no carbon. I dose recommended amount of excel daily and my lights are on for 9 hours a day. I have mollies for live stock and the plants are (please excuse the spellings)several crypt wenditti brown, several crypt green gecko, several bacopa monneri, several hygo Corymbosa, a couple java fern, a larger sword, a bunch of crypt Spiralis and some kind of grass (just one 3 inch stand)
I have some kind of liquid fert I got for free that contains a few things but seems like not a lot of what's needed. Everything is going okay but I am going to run out and would like a cheaper, decent all in one fert (along with my excel) is there a diy way like a certain miracle grow or something from Walmart I could use? I'd not what do you suggest. Cheap, easy all in one. Doesn't have to be perfect, just keep the plants growing and healthy and not cause massive algae blooms. Thanks.
