SO story of my life i've wasted about a thousand bucks on this one 10g tank in trying to cycle it and ive found out that the real problem was the low ph which wasn't letting my tank mature. so my question is how can i get my ph to 7 or higher my current tank ph is 6.0 using an api testkit for freshwater my tap water has a ph of about 6.6. i really dont want to buy anything or using baking soda but what i do have alot of is sea shells from the beach. so this tank really what hapopened was a t first i had fish they died left ammonia tank didnt cycle so i drained the tank put water it still had ammonia from the fish so i decided to go fishless cycling the ammonia went from 0.75 to 3ppm and know i just did a 50 % water change hoping it would ragulate my ph i currently also have shells in the tank not crushed or anything just how they were at the beach.I've wasted one year trying to cycle this tank and still nothing so i've had alot of patience the tank has gravel it runs on an aqueon power filter 10 and has an air pump that has air bubbles please help i really don't want to give up fish cause i love fishes and that''l mean the fish that died before died for nothing I've bought cycle, bio-zyme, stress zyme ammo-lock, everything please im open to any suggestions thank you for your time
