Hello everyone, i live in Hertfordshire and i have hard water - gh22 kh13. Tap water ph 7.2/3 degassed 7.9/8. Ive read literally hundreds of threads about fert dosing and about ca/mg ratio and relationship and also about if kh effects anything.
I have a 125l tank with a fluval 2.0 fresh and planted running at 100% and pressurised co2 at uncountable bps with a 1.2ph drop (from 7.9 to 6.7) and stays there during the whole photoperiod. I dose full ei, i should probably dose half ei as i have a medium planted tank but after reading stuff about hardwater and calcium preventing uptake balance of other nutrients i went with full dosing.
According to my water company average calcium content is 130ppm and magnesium is less than 1ppm, i do add a heaped teaspoon of mgso47h20 with every water change giving me about 5ppm magnesium but with 130ppm calcium i dont dont if thats effecting the uptake of other nutrients.
Does anyone else have experience with very high ca blocking/unbalancing nutrient uptake?
I dont dont really have any major algae problems apart from bba on manzanita and little bits of old growth on the slow growers but they get cut out regularly.
In terms of growth my hygro polysperma grows 1" a day, but sometimes has wavy leaf edges if i add more mg even though my ca is very high, or this this the mg and k relationship thats causing wavy edge?
I cant cant seem to grow ludwigia palustrias, it grows ok but seems pretty stunted and new leaves look deformed sometimes and lower leaves get bba.
Im sure lots of people have high ca and would love to hear their thoughts on how it interacts with using EI etc.
Thanks
