...is there a right way to do this, or is it just a case of doing it? My tank is about 200l, I have just over 2WPG lighting (on 11 hours a day), inject CO2 using a FE and using a drop checker believe I have it stable (the DC is green). Substrate is plain gravel. Plants are mainly cryptocoryne wendtii, h. corymbosa, h. salicifolia (I think) and sagittaria subulata. I currently use Seachem's full range of liquid ferts (along with JBL The 7 balls in the gravel) and am dosing twice weekly. Since I changed all the light tubes a few weeks ago the plants have been pearling consistently (although the crypts are pearling more than the hygro's which, given the speed of growth I expect from the hygro's, I find odd). Water change is an approx 50% change once weekly. Q1. I would like to switch to EI using dry ferts, but I'm not sure if there is a right way or a wrong way to do this? Q.2 Also, I keep expecting to hear a squeek as I walk, but I'm wondering if I can incorporate my remaining liquid ferts into this since I'm running out of some, but not others. Q3. I vaguely remember reading a comment of Tom barr's somewhere that one of the keys to success if finding a routine that suits you and sticking to it. Well, I'm a lazy cow. Honestly. I don't want to daily dose - I just don't think it will happen (hence the reason for dosing my liquids twice weekly) Can I adjust the dosing likewise? Similarly, would it be practicable to say halve the doses and do a 50% change twice fortnightly, or do I need a swift kick up the behind for just suggesting it? Sorry for all the Q's!
