it was made from a design i saw on here from a craft material i think intended for crochet. its plastic and i used fishing line both should definitely be inert. and guess what im so happy my ammonia is at 0 now and i got a mean 1.6 or higher NO2 spike now. im so happy my tank is almost cycled :).
im just going to keep an eye on the ph. im ok with it being 8.0 for now. after this tank fully cycles i may try to root out the problem.
oh my ive been waiting so long now i have to think about stocking it!!!
