righty:
Go back and read that thread. It took several of my posts before he realized I have an aerobic operation where there is no ph drop in the shells.
And here is what he wrote when he did:
OK, then the pH won't drop too much inside of it, and dissolution should be minimal, unless the calcium, pH, alkalinity, or somecombination thereof drops low enough in the flowing water to cause some dissolution.
At a pH of 7.9, calcium 250 ppm, and an alkalinity of 2.0 meq/L, the shells may begin to dissolve. It does not happen when the pH, calcium, and alkalinity are normal for seawater.
You keep using Randy as support when in reality what he wrote is not support for you. According to that post post (and his recent response to me) you won't get much dissolving at all with the parameters you say you have.
The shells are dissolving whether or not anyone considers it normal ocean values.
Again, you have no evidence of that, just
post hoc ergo procter hoc. Again, you won't even do the simplest experiments of testing your tap water or removing the shells to see if ca drops.
My sps is growing also.
Corraline is slowly spreading.
a halimedia is showing slow growth.
will All that continue probably.
Yep. And I think none of it has to do with oyster shells or plant life.
Will you ever admit it probably not.
I have admitted to it from the beginning of responding to you - that you still fail to understand that is baffling and frustrating.
Will things have little cycles sure.
You really shouldn't. A tank should become pretty stable unless there are problems.
but I do have 400-420ppm calcium and 2 meg/l alk. ph of 8.4 just before lights out and nightly ph drop.
And I don't know what that has to do with anything other than to show that Randy says you will only have minimal dissolving at those levels.
what I don't have is $s/pound live rock, special super duper live sand, Kalk drippers, manual dosing, automated dosing, calcium reactors and so on. I don't even have to scour the nation driving 100s of miles to find that special rare sand. You know the one that says right onthe bag "not recommend for aquarium use" :lol:
And you also have a euthrophic tank.
I am concerned with your above characterizations. You are too focused on the people in the hobby that are fad followers. Cheap live rock is available, so is sand, very few people think buying live sand is a good idea. I have no manual dosing and no manual top off and piece of mind that my tank levels remain stable through my inexpensive auto top off/kalk reactor and DIY ca reactor.
You also fail to take into account the differences in running a system with 250 gallons, like mine, and a system of less than 55 gallons, like yours. On a larger system, automation can really cut down on regular maintenance.
You may not like automation, and that is your prerogative, but I don't understand you disparaging it of itself. It does have its place.
My entire sand and filter system cost $20 plus the cost of a mag 5 pump.
Great. Not sure what that has to do with anything, but great.
So I'll just let the corraline and sps grow. And not worry about the calcium and alk values. And all the other equipment and methods either.
What are you talking about - you do worry about the ca levels. Your tank is 2 years old and only now are you beginning to see coral line?
No one wants you to worry. What people seem to want is for you to stop picking and choosing your evidence, to stop claiming you have been scientific, and to stop stating your ideas as fact even though the evidence contradicts you.
I'm in one of the new homes there....nice place but the F16's from Luke bug our dogs
