Going the crushed coral route is the way I had to go with my goldfish, too. My tap water is rather soft. Basically what I did was got a small filter media bag (I've seen them near canister filters at pet stores) and added a cup of crushed coral. You can buy crushed coral as a substrate for marine tanks. I have the Caribsea crushed aragonite, and it works great but you have to wash it pretty thoroughly beforehand. Because it's a substrate marketed towards saltwater tanks it often has salt residue on it.

If you do go this route, I highly recommend getting a GH/KH test kit. The crushed coral will alter both the KH, GH and pH. You will need to test rather often when you are adding the coral.

One last tidbit about the coral. It does NOT need to be replaced as often as carbon. I still have the same bag from a couple of years ago in my tank and have not noticed a decrease in buffering capacity.

First of all, ignore TopFin's advice about replacing your filter media regularly. Keep it in there until it falls apart. That's where much of your nitrifying bacteria live. For your coral or other calcium suplplement, you can use a mesh bag from the petstore, a piece of polyester/nylon stocking or similar mesh to kep it in the filter.

A low pH is not toxic to bacteria. It just grows more slowly in a low pH environment. Using Safestart will still be faster than not using it.

Please keep track of you process and share the results with us. Thanks.

In another thread, Ricky said eggshells would work. Would you recommend that in this case, Rick?

When you say "keep it in the filter", what do you mean? I don't really see any room in there to drop a mesh bag in. The filter cartridge does allow for the addition of other media. Should I put it in there or just put it in a mesh bag and leave it in the tank?

You can also tie the mesh bag in the tank if you don't have room in the filter. My aquaclear has room for something like that, but in a tank I maintain for my mom's middle school classroom there isn't enough room. It's ugly, but the filter bag just hangs on the side near the filter. The important thing is to have good water movement around it.

ok, I added some crushed coral in a media bag and placed in the filter compartment. Will test later tonight to see if any impact. pH this afternoon around 6.2.

This won't happen fast may take a few days before you see an effect.

Ok, so just tested and pH is around 6.8. I was going to do one more PWC this evening and then add the TSS. Does that sound o.k.? Oh, and is it ok to add the Seachem Prime for this water change? should i wait to add the TSS for any amount of time?

Right. Change water, add TSS. Always use Prime with water changes.

I've also read that the bacteria will grow better in warmer water temps (mid 70's). My water is constant around 68-70 but will warm up a few degrees with the hood light on. Is this a good idea to help bacteria growth? Any impact on the fish or water quality raising the temp?

The bacteria grow better in warmer water, like 80* to 85*. Adjust your temperature for your fish. You won't notice any difference in cycle time.

Raising the temperature raises the percentage of free-ammonia and lowers dissolved oxygen, which you don't want.
