[Water Question]

KH and GH are 6 drops which appears to be soft water. My pH is off the charts really high and I have no idea why. My hot tub tends to how a low ph when I fill it. Attaching all other values. I have two Fluval plant light strips. They are I believe the longest sizes and they span the length of the tank. What can I do due to the depth? 

[Water Question]

I am looking for some help with my water. I have well water but it does have a water softener/brine tank as well as a sulfur filter. I have a heavily planted tank that is heavy on fish as well. CO2. 120 G tank. I can’t seem to get plants to thrive. Sometimes I’ll notice some darker green on the leaves of the plants. I have the Fluval lights as well on my tank. I’m not sure if my mistake is that I use a generalized plant fertilizer or sometimes I don’t use anything. Doesn’t seem to make a difference either way.

I did that unfortunately

Every time I used a sponge filter, it gets this awful squeak. How do I prevent this?

[Fluval Plant Lighting]

I'm seeking some help.

I have a planted tank. Community Fish. 125 G. Canister filter. 2 jets for circulation. UV light. 

Black beard algae issue. CO2/02 Injection.

What are some good light cycle suggestions in general and to help with this issue?
