Hi
Having experimented with a Walstad style fish tank over a year ago and not really getting the results I desired, (most of my plants appeared to melt
) perhaps due to my poor combination of high light 3.5w per g in a 120l tank, little C02 (P.H 8.0, K.H 20) and not enough nutrients (NO3 & PO4 0) I have decided to give the EI method of dosing a try. However when I started looking into the quality of my tap water surprisingly I discovered when the water source I use for my tank was recently switched to soft water (GH 0) my plants actually appeared to benefit and grow better then they had proceeding
. I was wondering if this could be due to the relatively high levels of P04 2.5 (Full readings below) as I had always believed that such a sudden change to a low GH in comparison to before (see below) would cause the plants to disintegrate? If this sudden improvement is due to the Po4 is it worth me using the soft water for my tank and, adding something to boost GH, instead of the very hard water GH 20 which I have always used before with very limited successes
?
I was planning if I used the harder water to dose KNO3, KH2PO4, aim for C02 around 30ppm and TMG for traces rather them seachem flourish (I heard the algaecide properties of seachem can have a bad effect on mosses
? which I plan to have a large number of in my asian biotope tank) However I was unclear of the dosage I should be aiming for with my moderately bright light and if I should be adding anything else such as extra K or P?
Thanks for your time, any advise or comments welcome
