Last night I set up my new 38 gallon tank with filtered pool sand and a couple of pieces of driftwood (seeding from established tank). To commence a fishless cycle, I added 1/3 cup of pure ammonia (based on advice to use about a 1/2 cup for a 55-gal. tank). I had forgotten to buy a test kit so I wasn't able to test my parameters until today.
First, I tested the pH in the tank water. It seems high. To eliminate other influences, I tested my water straight from the tap. The results were the same. I'm attaching photos of my pH and High Range pH results. I'm having trouble eyeballing it... 7.5? Based on my research this is higher than ideal, although not extreme. Should I expect this to be problematic? Should I try to adjust it?
Second, I tested the ammonia. I've also attached a photo of that test result. Thank goodness there are no fish in that tank. 8.0ppm or more! I guess 1/3 cup was a little much
Why do think your pH is high? What are you planning on keeping in there? 7.6 is fine for almost all plants/critters out there and messing with pH and trying to change it are more work than is need and usually end up harming the fish and plants more than it would benefit. a pH of 10 is high. 7.6 is normal for most tap water.
20g platy, , 2 x 10g shrimp, 3 x 20g shrimp, 7.5g shrimp and 1 great dane/mastiff puppy.
I haven't finalized my stocking plan yet, but ideally I would like a pair of apistos, a pair of GBRs, a sparkling gourami, and a school of emerald eye rasboras. For the most part, my research is telling me that they'd do best with a ph of 7.0 or less.
