TheKipf Posted August 27, 2013 Share Posted August 27, 2013 Hey guys, Wanted to share my progress on the reboot of my 90g reef tank. Back Story I had this tank back in 2010 and had it running for almost two years before moving into my house in Leander. When i bought the house, the tank condition had greatly decreased due to the most relentless dinoflagellates (or at least I believe it was) infestation I had ever seen. My spirit was crushed, so I tore everything down, sold off the live stock, and was certain I was done with reef tanks. However, I made a horrible mistake - instead of selling off the equipment I stored it away in my garage where I spent the last two years staring, tripping over, and walking around it. Finally I caved in - time to reboot the tank! Considerations I love my little house - but I didn't have a great area for the 4ft long tank in my living area, but I did have a nice area in the kitchen. The whole house is pretty open - so my biggest concern was noise coming from a tiled kitchen and echoing all over the house. The 2nd consideration was really to see if I couldn't improve on my set up and equipment - being the first time around I just 'learned on the fly' and really could have used better insight going in. The Stand First big thing I tackled was the stand. It had some wear from the original owners, and could greatly benefit from a little bit of paint and shine. I hit the sand with the random orbital sander - and hand sanded the parts I couldn't get with the tools. I tried to spin this part of the project as a positive thing. "Hey - I have an excuse to buy a new orbital sander!" - but it did little to help. I really...really... really hate sanding. Here's the finished product after spraying with new paint. I used an outdoor semi-gloss paint - so hopefully it will stand up to the salt and water and clean up easily. It really did help breath life into a tired old stand! Amazingly the whole painting process went rather smoothly - with little error. Here's step one of trying to make the whole system quieter. I cut out a sheet of ply to make an enclosed backing for the stand to hopefully trap in some of the sound (and give it an over-all cleaner appearance). To help protect the sump from getting two warm - I installed two computer files to move are in and out of the stand. I have them hooked up to a 4-pin MOLEX to 120v adapter that I got off of newegg to run the fans. They worth pretty well - and move a ton of air. However - I could have invested in quieter fans. These aren't too bad - but can add a little noise to the system. Here's the reverse look of the new backing to the stand. I've since moved the fans and screwed them in from the inside of the stand so I can access it later after the tank is set up. I also installed in some industrial sound proofing material (~1-1.25 inches thick). This stuff is EXPENSIVE but man does it work! This is the finished look with all of the sound proofing material installed. It cuts down on the area I have to work with for my sump - but everything fits in there OK with the equipment I have now. Hopefully it won't hamper any improvements down the line. Sump I decided to re-purpose my 20gl sump again. The 48x18 cabinet didn't allow me many options for sumps - and I couldn't find a 23gl tank anywhere. Still - there were some room for improvements. Let me first apologize about the fuzzy pictures you guys are going to get. I was poor at documenting my progress - and I think working in the heat of August just makes pictures blurry. My first sump had the refugium section in the center baffle with the return at the end - and the skimmer chamber at the other end. That was fine, except I got way too much flow going over my sump and it was difficult to keep any kind of substrate in there. I re-baffled the sump to have the refugium at the end, and moved the return chamber to the middle. I also opened up the return chamber a bit more to allow more evaporation. I also correctly baffled my skimmer chamber to the suggested 6 inch operating height (which wasn't even a known consideration for me before!) Leak test looking good! Oh - so funny story. If you ever buy industrial adhesive (for the sound proofing) and Silicone Caulk (for the baffles) - be careful not to mix them up! I totally set all my baffles in place with adhesive the first time around! Luckily I realized about an hour later and was able to still pull them out - however - cleaning the tank again with the razor blade was not fun! Here it is in the tank! I still have some room to move around there (although not much room from the front of the stand to the back. I updated my plumbing here some. I placed a T with a ball value from my return pump to the refugium area. This way I'll be able to regulate the flow going into my refugium. I had debated about doing this with the overflow into the sump - but the more I mapped it out the more complicated it was and the more risk was involved (in terms of flooding the tank). So this is what I decided on. I also added a check valve (which I'm not 100% sold on yet - we will see how it goes when it's in action) to help stop back flow into the sump and keep my skimmer levels consistent. Note you can see the fans now mounted on the INSIDE of the stand here. There's a FTS of how she all looks put together! Yes, yes... I know that door is hung crooked... I'll fix it... eventually.... And it finally begins! Added in some sand late last night. Can't wait to get the LR added in here in the next day or two and get this guy running and cycling! I still have some wish lists to add yet. Tank controller / Mp40es / ATO and a few other items. I'm hoping to get these in place as the tank cycles. I appreciate the input - and will hopefully keep documenting the progress!
