Using liquid plant food during the cycle?

[jhays79]

I have a few different plants in my aquarium thats cycling, a few anubias and a few anacharis. i picked up some API liquid plant food, but I am unsure if I should add it while the tank is cycling. will it adversely effect the cycle?

no, i don't think it will affect the cycle. it's just liquid ferts. just that, it might inhibit excessive algae growth. basically you only need liquid CO2 for a cycling tank with plants, as there are a lot of nutrients in a cycling tank.

proof of that is when i was cycling my tank and i added regular ferts, i only added a lot of algae on the tank as well.

I personally wouldn't bother until the cycle has finished. The plants aren't going to die if they go a couple weeks without ferts. With water changes all the time, it's only wasting the ferts. But regarding your question, no, it will not "hurt" anything.

I don't do water changes yet, since I'm doing a fishless cycle. i will add a little bit and see what happens.

You may not need to dose a lot of ferts. The plants will also use some the ammonia while you are completing the fishless cycle
