My PH is currently at 7.8-8.0. Is this too low? How can I raise it without increasing alkalinity?
epson salt raises ph without effecting alkalinity. i don't know if you can use it in a marine
it's a bit low but it's sometimes better to have it "low" and regular than always going up and down .
A few questions.
Do you run a calcium reactor?
How deep is your tank?
What supplementation are you using for calcium and alkalinity?
How are you testing your p.H?
What type of circulation do you have in your DT?
Hi Tony... No calcium reactor. The water is 60cm deep. I dose bicarb in the morning and calcium chloride in the evening. Testing with a new SAGA pen. There is hectic flow in the tank. about 40000 l/hr in a 1.5m tank.
which tank is this the low ph in?
The big one.
Drip your calcium chloride opposed to adding it all at once. A sudden addition of calcium chloride can cause an alkalinity drop whihc will drop your p.H
Your Ph is fine bro. What is your Alk at?
Calcium hydroxide absent. IMO the proportion of calcium chloride is out of sink with the hydroxide addition. In tanks where Kalkwasser only is administered high pH values are common.
Thanks Jean and Mek. That's what I wanted to hear. If it's not critical, then I'd rather leave it than start see-sawing with new dosages.
Thanks NJ. That sounds like a good solution(get it?). If you think that 7.8 is too low a PH value, then I'll give it a try?
just for interest sake i tested my koi pond the ph is 9.5 and my small salt tank 7.9
Yeah, just leave it, as long as your Ca and Alk are fine. That ph levels will not cause any harm.
