ammonia rise????

[pitchblack]

hey ppl since the last spat of event my tank is on the cycle process.

ph 6.8
ammonia 0.25ppm
nitrate and nitrite 0
gh 80ppm
kh 100ppm
iron 0.25

I have got a bottle of ammo lock. wondering if anyone else has used it??? It locks the ammonia up and turns it into a non toxic form to be taken in by the filter. I have put nitrate preventative bags into my filter and added cycle with a 20% water change. Is there anything else I can do. Havent had to deal with ammonia for a while so just wondeing how ofter I should be doing a water changes????

thanks
