Hi just got back home from 4 different fish shops and very dissapointed indeed, i was gonna by some planting substrate ie tropica or Ada but firstly they didnt even know what i was talking about, asked a chap in the shop first he looked round the whole shop and was looking around in the medicines, he then showed me gravel, after all this he went to checkout and asked 1 of 2 ladies there and the same they both didnt have a clue!!! I was like damn this a some crazy blahblahblahblah.......She was talking like she knew what to do but i knew everything she was telling me was wrong cos id done my homework, i was armed with info man!!! I been on here for the last 4 weeks...ha ha. She tried to tell me i could just put in a bag of eco complete mixing it in at different periods or even next to the plants. I then went to a couple more stores and just headed back home without buying anything. I have now dedided im giving my order online to the greenmachine who i will be buying tropica or ADA, is eco complete any good guys?? I was at the ready with my c/c but nobody had the foggiest about anything....it looks to me that the workers in the shops dont know much and we are just better to do our own research, it looks to me as if fish shops are not regulated in any way by some sort of union and they just get overlooked!!
