Nutri-Calc indicates 3 1/8 tsp MgSO4 3 times a week for my 77 (UK) gall tank which seems quite a lot - I'm sure it would have a devastating effect on me
I have dosed it at this rate for the last week and the plants have definately improved in growth and appearance, however I have also noted that new leaves on my HYGROPHILA are very curved-in on the sides - is it likely that the MgSO4 dosing is causing this.
All the other plants seem fine.
The other point I've noted is that cabomba has taken-off like crazy since switching to EI. I have to trim about 6" from each plant every day, mainly because the internode distance is now about 6"
I've been a convert to Tom's EI dosing since 1/8/06
100 UK gall tank - approx 77 galls H2O
3 x 36w triton tubes - 12 hrs/day
2 x 150w metal halide lamps - 9hrs/day
Eheim 2329 wet/dry (bio) filter
Eheim 2217
Pressurised CO2 when the MH lamps are on (around 10 bubbles/sec (?)too fast to tell really)
pH of outgassed tank water ~7.6
pH before CO2 switches on ~7.1
pH at lights out ~6.4
(pH values from pH controller)
Thanks
