Right have been keeping fish for 15+ years have had reasonable success with plants
Now I have 3 tanks on the go 2 of which are running fine but have only been going about 2 months.
Now the main tank in the house has been going for just over a 2 years and has never caused any problems until now.
But is suffering from a low ph reading, which is concerning me as I am intending to start using the Co2 on this tank which I understand will lower the ph even more.
The tank is fully planted which as you can image aren’t doing that well with low light and no co2 and only the occasional dose of fertiliser.
Now from doing some research it looks like my problems could be down to a low KH reading which I understand could be caused by the plants? (i.e. not being given any fertiliser)
All tank in habitants are healthy and no deaths in 5+ months
Test readings.
NO2 - 0
N03 - 10
GH – around 14
KH – around 3
pH 6.5
Tank - juwel Rio 400
Filter - standard juwel + Tetra Tec EX 700
lighting - standard juwel (week point)(but soon to have 2 more 4 foot cubes added )
no c02 (as of yet)
15% water change every 2 weeks.
So do I need to raise the ph and amount of KH in the tank and what’s the best way of doing this?
thanks
Andrew
