Another thing I have seen someone here do, is mix some blood and bone fertiliser into clay and use these as DIY root tabs. I'm not sure of the exact ratios, but I'm sure a quick google search should turn up something. I think blood and bone is slower release than something like Osmocote.
However, I wouldn't recommend adding terrestrial fertilisers to your tank unless you know what you are doing.
I have found my crypts have really established themselves in one of my temporary tubs. I used propogating sand I picked up for about 5 bucks a bag at the hardware store. It is full of clay and supposedly, micronutrients, and is giving me good growth results with no root tabs used.
lol.. i never could keep anacharis alive, it lived for a week, then took a dive... i had a whole forest made up with strings and i think between the warm temp and the betta making them into a salad killed them off...i love my hair grass,
id love to get some banana plants for my non planted tank seeing as i have a large bag of floramax in my closet still i really like the lilly bulbs too, just takes over the top of my tank a bit...
Hmm I see. I plan on having a Betta and MAYBE some shrimps in the tank. By the time I get around to having them in the tank, the tank should be cycled (cycling is in progress now)
In such a case, I can't imagine having such few water changes. I was thinking a weekly water change of 30% would suffice. In that case, I guess I give plant food at every water change? I can also limit my fertilizer to once every two or four weeks?
