Thanks for the answers so far....
I use the Nutrafin testing kits. My local fish store confirmed the PO4
levels of our tap water are pretty **** high. But as mentioned here there are alot of things I could improve.
The lighting is 2 T5 24W bulbs over a 46G tank. That are plant bulbs so as an estimate id say potentially 1.8 wpg
I spent along time calibrating and testing different ways of calibration fluid when I was setting up the PH monitor. This is one of the reasons it took me so long to run it in.
Especially when I initially found as soon as I turned it on and left it for a day the fish were all gasping for air.
I've improved things now by increasing the surface agitation with an extra HOB
filter making a nice ripple (which was totally lacking before).
is probably a touch less then 4 as the kit rounds it to the nearest whole digit. So on the safe side id say 3.5. Working off the night/day range of variation in PH of 0.2 if I dropped my upper cap to 6.6 it would hit 6.4 by lights on in the morning. Ranging from 26 -> 41ppm.
I suppose this is a better figure then I have now, but will it adversely effect the plants or worse the fish?
Would I be better adding one of these airstones i've heard about or just increase the surface agitation using my existing extra HOB
I've been removing alot of the dead leaves every week already. Thankfully the Amazon Sword grows fast and thick.
I'll take some more pictures soon and add them to my diary thread this week. I've added my dwarf clover foreground now.
p.s I'll start a new thread on EI and my dosing later this week. Its one I need to get my head around.
