bleaching

My alk is low (5.6 dkh) I need to do an adjustment and get something to dose on a regular basis. I don't want to wait a week for online order. Where is a decently priced place within an hour of Flushing (Flint area) that I could pick up? Any suggestion on what I should use?

I have a pair of TaoTronics dimmable/programmable LED’s over my 75 mixed reef tank. I currently have the blues set no higher than 50% and the whites at 40% for about 2 hours around noon til 2, then they dim down by the 1/2 hour. My question is should I increase the blues for better coral growth...

I have over 150lbs of real reef rock. It is a mixture of various types of rock but it is all real stuff and not reefsaver or Marco. Alot of the pieces are very large as you can see from my hand in the picture and many very unique pieces. $150 takes it all! I bought to much for my build so just...

Still need to get some more rock. Prefer Pukani but will also take fiji if the price is right. Not reefsaver or fake rock. Looking for a good deal on this rock. Let me know what you have. I will be bleaching it anyways so it does not matter if it is live.

When I got my APEX six months ago, the conductivity probe would not calibrate and it went back to factory default. I stupidly forgot and tonight I went to recalibrate and same thing- the APEX would not calibrate and from what I can tell, my water has been at 1.020 for the last six months when I...

I have been in the hobby for close to 10 years and haven't come across anything like this. My tank has been established for 2 years and within the past couple months almost all of my LPS corals (mostly brains) have been slowly receding. The past week or two they have been getting much worse and...

Anyone know what's happening with this white/faded spot on my purple bonsai? It' just showed up. Nothing else going on in the tank. I haven't tested the water for two weeks so I suppose I can if anyone needs the params, but just wondering if anyone knows off hand what the deal is?

I was doing a water change which left some corals exposed, but when filled it back up I noticed the skeleton started bleaching. Question is do I leave the corals be and they should heal themselves? or do I have to trim the pieces off. If I leave it be will it destroy the rest of the coral?

As I have not had much interest in my complete setup, I have decided to try to part out. I will be listing livestock, live rock and corals first, then I will begin selling drygoods only after all livestock is sold. I will sell corals as they are spoken for, but I do not want to sell any fish...

About two months ago I set up a 30 frag tank which is plumbed into my existing 200g system. Water leaving the Carbon and GFO filters now supplies the frag tank and then gravity drains back into the sump. I have a 75 metal halide lamp that is on for 12hrs per day, hanging about 18"above the...

Just got my water tested after a recent water change. Here was the LFS numbers - KH - 80 ppm PH - 7.5 Nitrite & Nitrates - 0 Phosphate - .25 ppm Should I be concerned over that Phosphate level? I thought of investing in some "Rowaphos", or similar for my 2nd reactor chamber. - I own a BRS Dual...

Hello. I recently started a saltwater tank and I started the tank with about 20 pounds of live rock. My plan was to add some dead rock to bring down the cost of starting the tank. I bought some dead rock and they had a lot of algae on them. I tried scrubbing the algae off but it didn't work. So...

I don't know if any Michigan reefers have seahorse tanks...it would be great to look at other people's setups and meet some people that have attempted breeding them. I have two girls that I've had about 2 weeks now, eating like champs. Pictures attached...the site is not allowing me to create...

As mentioned previously, I got a new 'baby' GBTA. He seems to be settling in well this morning. When I turned on the light his tentacles were long and waving in the current but he quickly responded to the lights and pulled in/bubbled up. I gave him one more mysis first thing and he gobbled it...

I am looking to use gfo for the first time...any tips and tricks? some reactors better than others?

Hello. I'm having a problem keeping stoneys. I've had my tank going for a while. I have maily zoas, mushrooms, rics, candy canes, and frog spawn. All of them multiply great! My calcium is always at 450. All my other levels are spot on. I've been told that I need to run a gfo phos reactor. Is...

I got this two LTA last week at Stingray Bay both are about 6-8" round. Both seem to be healthy but the only thing I was wondering is why both of the anemones mouth are open all the time.???? Can someone shed some light on this. Thanks everyone

I recently started running an evergrow D120 led over my 20L. I have a little over a dozen sps frags. A few bleached, one browned... Leads me to wonder how you can tell whether you have too much or too little lighting. Also leaves me wondering how I'll know when my light has reached optimum...
