Evening Guys
A couple of things I hope my friends here will be able to help me with (again)!!! My Nitrites and Nitrates have been a little high of late, which I've put down to there now being fish in the tank, feeding etc, and the Red Sea Skimmer that I had, not working as effectively as I had hoped. Carried out a 10% Saltwater Change on 2nd Feb, followed by a 5% RO top up on 3rd and 10% Saltwater Change last night. Parameters tonight were:-
Temp: 80.7
SG: 1.022
pH: 8.5
Ammonia: 0
Nitrite: 0.3mg/l
Nitrate: 20mg/l
Alkalinity: 11.7dKH
Phosphate: 0.5mg/l
Calcium: 440ppm
Is it just perserverance with the water changes or should I try something else? Another thing, my Leather Finger has been looking a little ropey over the last couple of days, not puffing out as much as it normally does. I had moved the flow about a bit in the tank, and initially put it down to that, I assumed that it wasn't get as much flow as before, so moved my PH's and filter out back to where there were. No change! I've also installed the new skimmer this week and noticed that the temp in the tank has steadily increased over the two days its been affective in the tank. So wondered if it was that, I normally keep my temp at a steady 80, but it has gone up almost a degree, which is probably about 2 or 3 degrees above ideal for the coral. I guess I shouldn't be too concerned, as the polyps are still making a significant effort to extend, but any advice as always will be greatly appreciated. Rather unexpectedly my SG has dropped from the normal 1.024/1.026 to 1.022, tested the Saltwater (LFS bought) and it went 1.018 on the refractometer!! Think I'll make sure I mix my own salt from now on!!
