A question for the experienced plant keepers

A question for the experienced plant keepers

I am starting my journey on my first planted tank. A few things about it, it is a 75 gallon tank, I am running the Emperor 400 by Marineland. I am using a crushed limestone/sand substrate, about 2.5 to 3 inches deep. I have recently upgraded my lighting from compact fluorescents to 10K LEDs. I have been in the hobby since I was very young and love it, but this part is new to me. I have always enjoyed the look of the bubble curtains on the back wall and the way fish swim through it. Will this help or hurt in a planted tank? I would like at one point to grow frogbit and duckweed and I am worried that the water will be too agitated by the bubbles.

Thanks in advance for any answers and comments.

Excessive aeration in a planted tank can cause the CO2 to off gas. You can get away with the frogbit and duckweed, not as touchy and needy as stem plants. If you plan on a lot of cover, consider lower light choices for the inside of the tank like swords, crypts, anubias.
To accomplish your curtain across the back without making a lot of current, just get a smaller air pump than what is recommended for your size tank.

I don't think that crushed limestone is beneficial to a planted tank. It will add hardness to the water. Anubias will survive but not the swords.

Sort of true. I keep swords and crypts in sand, but add root tabs and they do fine.

Most freshwater aquarium sand is inert and won't affect hardness or pH. Limestone, however, especially crushed is only suitable for hardwater aquariums (African cichlids, many live bearers, rainbows..) and not good for softwater fish or plants. Limestone is made of Calcium carbonate, inert sand is silica.

I may be wrong about it being crushed limestone. It is the new national geographic sand at petsmart. I thought it was crushed limestone because of the grain size. I already have hard water and do not need the pH raised any higher. I have mixed the black and white sand substrate.

I have another question because of what has been discussed so far. Will an ro water filter help me lower the pH? I live in an area with loads of minerals in the water.

Again, thank you for the replies and advice.

If you use straight RO yes, it will lower the PH. I use an RO but I use the drinking water part. If I used straight RO my PH would be too low for the fish I presently keep.{Goldfish, bettas, cats} I used to use it for chocolate gouramis, some touchy rasboras. What is your PH straight from the tap, and what is your PH in your tank presently?
