![]() I didn't do too much with the project this last week/weekend. Needed to do yard work and had MIL 60th bday.
I did get the last few coats of paint on the stand and got the media rack silconed into the sump. I bought the plywood for the stand skinning and a new blade for the saw, so I'm all ready. ![]() On the other hand, I have a vat of dirty rock that had half dried and sat in the shed for the winter. I bleached it a few weeks ago and refilled with RO water then kinda forgot about it. This morning I tested PO4 at 0.49 ppm (Hanna) and NO3 >100 ppm (maxed out Salifert kit). So I drained the water and refilled it with used saltwater from my 50-gallon. I might need to acid wash it...we'll see how it tests in a few days. |

![]() Let there be light! (thanks to riceboy)
It's an ATI Sunpower 6x39w dimmable T5 fixture. I plan to mount a couple of Reefbrite blue LED strips on either side. Not sure if I'll be wanting the XHOs or the if the Techs will do the trick. Maybe XHOs on a dimmer? This way I can run some high PAR T5 bulbs and have the LEDs for the blue supplementation. I'll be running a combo of ATI Aquablue Special and Coral Plus. ![]() |

![]() Thanks guys! I'm not quite done the inside, but I wanted to get some paint on it so it can dry well before the tank gets here. I won't be working in it again until Thursday.

![]() Just to keep this thread going while I wait for the tank, here are a couple pics of where the old frag tank is sitting. I plan to position the new tank a little further to the right so that it is fully in the livingroom and is more in line with the recliner for excellent viewing.
![]() I put some rock into the frag tank (it was all acrylic racks) to help mature the rock. ![]() ![]() |

![]() ![]() So I decided to acid wash the old formerly live, then dried dead rock. The latest reading was still over 100 ppm nitrate and 0.5 ppm phosphate after two 100% water changes (no change noted). I made some strong acid! ![]() I donned goggles, beautiful yellow rubber gloves, and shorts, tank, and sandals (ha!). I bought two 900 mL bottles of muriatic acid and poured them into 1 1/2 gallons of tap water. I dipped the rocks one at a time, and overdid the first one in about 12 minutes - that's some powerful mix! The rest of the rocks got about a 5-8 minutes dip, tap water rinse, tap water plus baking soda rinse (1 1/2 containers baking soda and about 3 gallons of water), then back into the rock tub filled with RO. A couple hours later I test the RO at pH 7.8 so I guess the rinse was sufficient. I will test nitrate and phosphate in a few days and see if there was any progress. Here's the first rock getting half dissolved (lol): ![]() Last edited by Myka; 06-06-2015 at 11:45 PM. |

![]() It's not that bad Doug. I've acid washed rocks before in much lower dilution for a much longer time (hours rather than minutes), but I found that some rocks require more time, and others require less. So I decided to dip them one at a time. I didn't want to spend all day doing it, so I made the acid strong. I didn't realize it would be that strong! It took me less than an hour to do it all include setup and cleanup, and cost me $12 for the acid and 40 gallons of RO. Pretty straight forward as long as you're careful about splashing.
