I'm not new to animal husbandry, I have a 30 year old corn snake and have had fresh water aquariums for years. I've also had a few saltwater tanks now and again.

I've recently cleared out a tank that had a fresh water turtle and some koi in it for about 10 years. I donated the turtle to an organization that does animal education and the koi to a friends pond. Now I'm left with a tank and felt like doing some experiments.

I have a 40 gallon breeder with a massive fluval (enough to keep a filthy turtle tank clean). I changed all of the filter media and filled it with about 30 gallons of water. I'm in the process of adding reef salt to the tank (it takes a lot of salt lol) and getting it set to the right hydro reading (I'm setting it up to the same salinity as the beach down the street; I live on the north shore of the east coast). I also have a 5 gallon bucket full of beach sand from the same said beach ... I collected the dry sand not the wet sand.

My goal is to add some rocks with barnacles and some local sea life (periwinkles, tiny rock crabs, hermit crabs, maybe anemones if I find any, or some star fish. I will not be adding any fish nor will I be heating the tank (it will be room temp 60-74 degree's).

So what can I expect? Are barnacle rocks a bad idea (I'm wondering if they won't spread all over the tank or clog up the filter ... the barnacles not the rocks)? What will grow out of the sea sand? I assume that I can put living rock and or store bought anemones in there if I want to ... or perhaps other crustaceans? Any thoughts?

This is more of an experiment ... I only paid for some reef salt ... and lugging a 5 gallon bucket of sand up the beach (ouch) so if things don't work out I i can drain the tank and rinse everything down. if any of you have any experience with this sort of thing let me know.

Thanks in advance for any input ... but if you're just going to have some mental breakdown on me for some tardo-reason please save it for someone else.

So I have the sand in the tank and I'm working on getting the salt up to where it needs to be. Now I remember why I stopped doing salt water tanks because you need millions of tons of salt to get the salinity close to where it needs to be and then you go 1/4 TSP over and you have 55,000 times the salt needed lol ... pain in the dick. The Ph. is 7.8 ... so I'm adding some Ph. up to raise that to 8.0-8.2.

The black things are little seaweed bits that I left in ... I don't have any lights or hood on it yet as i'm still paining the *** around with it.

I'm working on the salt ... adding 1/2 cup at a time to a quart of tank water, shaking it up, then adding it in. I test the salinity of the water 20 min later with the filter running so that it circulates and then add more. For a 40 gallon tank I have 11 or 12 lbs of salt in it so far. I know that it will probably take 5 lbs more to get it in the green but if I add 5lbs and 1/2 TSP it will turn into a salt block lol.

Any thoughts/ideas?
 
I have some API Ph. up but i think it is for freshwater only. What do you guys use to tweek the Ph. up or down a tinge?
 
What do you use to clear up slightly cloudy water?

Is there anything better than sodium bicarbonate for minor Ph. increases?
 
what is your pH reading? In general, we don't worry about pH. Alk is more important, and that is what sodium bicarbonate increases, not pH.

Cloudy water could be a number of things. Since it's a new tank, it's probably just cloudy from sand and rock settling, and will get better in time.
 
Everything looks good on the test strip stating ideal ... only the Ph looked a tad low.

Ph ranges from acid to alkaline ... so why do you say Ph doesn't matter but alkalinity does? Wouldn't a Ph of something like 6.4 mean the water is really low in alkalinity and a Ph of 8.4 means that the water is low in acid? Is there an article or faq on the site that can over the differences in a salt water tank?
 
What is the value? It probably isn't anything to worry about. Any value between about 7.6 and 8.5 is fine and normal, and it's very difficult to get it outside that range.

Alkalinity is a measurement of how well a solution can nuetralize acids, and we keep track of that. There is a sticky in the chemistry forum.

Thanks my man I will look.

All things given ... the tank is rocking and those little ocean buggers and beach sand are doing great. The only thing I worry about is a water change. I know you can just 'add salt' to the tank directly, so you need to plan for a water change in advance and have the replacement water ready. A 20% water change for me is 8 gallons.
