I've had this tank up for about a month or so. pH seems really high and so does KH. See attached parameters from my last water test. Fish seem to be doing well and other than a sword plant, plants seem to be doing well. Should I chase the ideal parameters or leave things be? Can anyone identify the black algae shown in the pictures? I just started dosing excel to try killing it. I also dose flourish, iron, potassium, and stress coat. I have two 24/7 planted plus lights and do have co2 injection. Any general suggestions for me? Thanks!

Also Ammonia says .25 but I find it hard to believe tank isn't cycled yet. I'd like to assume it's 0. The pH could have been 8.0 it was a tough judgement call comparing to the results chart

I'd worry about the ammonia. Are you dosing N and P? You can leave out the stress coat from your routine - not necessary. Cut off the affected leaves on the sword plant to help get that algae under control. It's black brush (BBA) I think.

As to the kH, pH, just leave them alone. I would check the tap water to be sure it matches - perhaps a rock is carbonate-based and causing both to go up over time.

I'd also suggest more plants - especially stems.

The only fish I see in there is a Swordtail. This is a hard water species. The high KH and pH are good. Is the GH also fairly high?

Figure out the cause of the present ammonia level.

Test you tap water if that is what you fill your tank with.
If the pH, KH and GH are higher in your tank compared to your tap water, then something in the tank is raising the levels (first thing I would test is the rocks).

To test the rocks, have a container of tap water with known/tested water parameters, then add stones and test in a bit to see if they alter parameters.
Or do the acid reaction test to see if acid (white vinegar or muriatic acid *use caution when handling*) causes the stones to react by fizzing (do test out of water).

What substrate are you using?

I see swordtails, rainbows, neon tetras, angelfish and maybe a yoyo loach.

Test your tap water. If it reads lower than you tank params, then test the rocks.

I may have found the cause of my algae. Late evening the sun sneaks through my front porch window into my front door window and hits the tank for an hour or two before dark. What do you guys think?
