Check to see if it needs a critical update or something.

The biggest change in reading according to time is in pH. I agree to try and do all of your testing at about the same time so you can better track any trends in your tank.

The RO membranes are only made by 2 suppliers the last time I knew so they are all the same whether in a $300 unit or a $50 unit. The units I have seen on Ebay use standard 10" cartridges which can be bought almost anywhere for the sediment and carbon filters. The Di filter is usually an...

This is a fish that IMO is better left for public aquariums and shouldn't be offered in the hobby. They are obligate feeders meaning they have a very specialized diet that most of us cannot adequately meet. I would leave this one in the fishstore even though they are quite beautiful to look at.

An RO membrane only removes a percentage of the contaminants in water, this is what they are talking about when they refer to a rejection rate. Most membranes have a rejection rate in the mid 90s, so lets say you have 200 ppm of phosphate and have a RO unit with a 95% rejection rate, you will...

I asked the same question to Anthony Calfo and he recommended gracillara, octodes, or chaetomorpha. I have experience with the chaeto and highly recommend it. He said to definitely stay away from the caulerpas if possible because when they go sexual they will release toxins and all of the...

What browser are you using? I have Mozillas Firefox as well as IE and if I have a FF window open chat will not work for me.

That should work out fine but I for one may need a reminder post (I am getting older you know and the mind slips sometimes). :roll:

If nothing changes I will be in Atlanta, maybe we can meet up while we are there.

Good one Sadie, unfortunately there is no settings for this kind of shock and you can't really control the electricities path. :twisted:

I would not get turbo snails, they get too big and act like bulldozers knocking things over all of the time unless they are in a big tank. Go with astreas, margaritas, trochus, or cerith snails for the glass and rocks and nassarious snails for the sandbed. Don't be tempted to get bumble bee...

I have ordered from www.exoticfish.com in the past but I really prefer to see the exact coral I am getting, this is mainly for size and sometimes color when posted pics are taken under actinics only.

I am mainly talking about fish waste and leftover food and detritus. If these are processed with a traditional biofilter they will be broken down into ammonia quite quickly, if given a chance for them to be consumed by tank cleaners there will be that much less ammonia that will eventually...

You are right that the filter is more efficient at processing waste and that is where the problem lies. By using LR as the filter the process is a little slower and this gives time for the waste to be used/eaten by other tank inhabitants. Nitrate is the end of the regular biological cycle, in...

I remember reading about the problem. It seems that on some of the tanks the switched neutral wires instead of hot so if only one of the lights was plugged in you could get a nasty shock from the other powercord. A very dangerous situation, especially since we add saltwater to the equasion.

As long as you can arrange your rockwork so you don't have dead spots (areas with no current) the AC20 should be enough, if not then add a small powerhead like a Zoomed 104 or the tiny one made by Tunze.

Again I am impressed, I really like the way you designed your overflow (I had never thought about a glass one like that). That sump/refugium is just out of this world. I am going to have to get on some of my projects soon!

A small container of gravel will also work, once they have attatched to the gravel you can glue the gravel where you want them.

Hair algae is a nuisance and can spread and choke corals out. There are few fish that eat hair algae so natural control isn't real easy. You need to find the cause and correct it before it gets out of hand. How old are your bulbs and what color temps are they?

I also agree that it could just be stress related, I have had several different fish that would darken when they were stressed or taking on an agressive posture. Keep an eye on him but I expect he will return to his usual coloration soon.
