Substrate change is needed sometime in the future.

My 72 gallon bow front has nice pond rocks in it. they are very pretty and all that stuff but they have a few problems associtated with them. They make the water very hard/raise PH constantly. I can never get it below 6.8 with co2 and chemicals don't do much. The reason I orignially used these rocks knowing they do this is because it was originally going to be a goldfish tank. I changed my mind after adding rocks and stuff. anyway, I need to change it sometime and I figure I mean as well do it up right since I wand this tank to be a nice richly planted tank.

So, experts on thsi forums, tell me what I should do! please! I see all thse weird substrates on here from ADA and such and have no clue what is right. Help me!

P.S. could the very hard water be what is making my Cambomba thrive? if so, will they die after substrate change?

Why is hard water a problem? For most people it isn't.

Goldfish are exceptionally adaptable, and I have seen them in almost straight R/O and liquid rock water. Perhaps some of the very expensive rare breeds might be picky, but certainly not the majority.

If you are one of the few, get rid of the rocks and buy an R/O unit. Problem solved. R/O units can be had for $130 shipped on Ebay, and it will be around 100GPD. You an justify the cost by using it for ironing water, houseplants, and drinking/cooking.

Some cabomba species like hard water, most plants are oblivious to hardness/alkalinity/pH

ADA Aquasoil will lower pH and hardness, but not indefinitely.

In college....so no aquariums for a while.....

You can use anything from pool filter sand (quartz sand) to Soilmaster to Turface, to some brands of cat litter, to ADA Soil, to 3M Color Quartz sand, to any of the commercial substrates. It all depends on how much you are willing to pay. The only one of the substrates I have read about that seems to help the plants to grow better is the ADA Soil. The others have lots of theoretical advantages, and grow plants very well too.

Not to high jack this thread, but where can you buy 3M Color Quartz sand in black?

The only places that might have it is a pool place about 50 miles from me.

ADA's soil provides nutrients to the plants, so water column fertilizing isn't so important - you should still do it, but if you mess up it doesn't have as much effect. It also is soft, so it doesn't scratch the glass. But, why it grows plants better I don't really know, but several folks have found that it does. However, there is always a catch - it does affect the water, making the pH drop and screwing up the measurement of CO2 by the KH/pH method, and may need water changes more often at first. Local fish stores don't usually have it either.
