When you say mini compact is it another light fixture that fits on the lid? If my math is correct I figured about 66 watts of light which was a 1.52 watts per gallon.But I never was good at math. I could be wrong this is how I did it. My light is a 6700.00k so I divided that by 44 gallons and came up with the 1.52 watts per gallon. Then I times the 1.52 with 44. Which came up with the 66 watts of light. Is that right?

My
pH stays around 7.0 to 7.2. I have hard water the last time I checked it I don't remember the number I will have to buy a new kit for that the other one got old and I threw it out. Now I guess I will have to pay more attention to that with live plants.

Yea I know about Ph problems. When I first got my angelfish the pet store was telling me to get the ph down for the angelfish so I started trying a lot of different things which just made everything worse so I done some research and I found out that it was better to leave the Ph alone. But in your case a crash is dangerous. Mine was not crashing the pet store was just telling me it was too high for angelfish. Anyway when I just left it along everything got alright.
I use Flourish by Seachem liquid for the jave fern I use almost a cup full every week but I think that might be too much because my fish where gasping at the top even after I turned up the air in the tank. I read somewhere that could be a sign of using to much. It calls for 1 capful for each 60 gallons. I also use the the Flourish tabs that you put in the gravel once every 3 months for the sword plant. I only have two live plants the rest are plastic.
I vacuum everytime I change the water once a week. The reason I was doing so much vacuuming is I had these little white thread like worms in the tank and I was trying to get rid of them. It got them except only a couple I also tried not feeding them as much. The reason I was thinking my tank could be off balance is I have had alot of trouble with my 44 gallon since I got the live plants. Some of my fish got sick and I lost one as you know and the other one I don't think is going to make it either she hasn't ate anything in over 2 weeks. But the big adult in the tank is alright so far.
I just have a 6700k Life-Glo 2 that fits in the original lid that came with the tank. The blub is about 17 inches.
Learning curve I never would have came to that conclusion by looking at your tanks. I thought you had least 2-3 yrs under your belt. Wow. There is just way to much stuff to learn about fish. I'm still learning and have been in it around 20 yrs. But I have never had the time to learn about live plants but that is something I'm interested in learning all I can. I want to make some time for it because I love the natural look in a tank. It is awesome.
Well, I have to go. Thanks for your help. Take care. Talk to you soon.
