Hey there jjstecchino, been tagging along. Great job constructing your sump. I was a plastic fabricator for a few years and fabricated some crazy stuff with a lot of different plastics. I too will be doing a build here in the near future, can't wait! I've been out of that industry for quite some time now and have been doing some research on materials. I must say I was very pleased to find a 4' X 8' sheet of 1/4" Acrylic for $131, and it's just up the street!
I have a current 55g system, a 72g bf tank that I will start soon, and a 180 that I intend to install into a wall later, hmm I'm definitely addict. I just wanted to let you know that I too have had issues with algae from time to time (even bigger issue with Grape caulerpa! sometimes I felt like my tank was a refugium). I just wanted to tell you that indeed you can deal with this algae issue by removing the nutrient load supplying its needs and providing "cows" as Melev said to "mow it down".
I'm just about to the end of my T-5's right now and will be replacing them in the next week or so as I'm starting to see some growth spots here and there. I recently added a Pacific yellow Tang and he's going banana's for this stuff. That's funny because my kids named it Bananers! Silly! Anyway, over the past year I have had some great improvement with my FOWLR setup with light upgrade, critters, fish selection, and frequent water changes. I'll see if I have any photos of this stuff trying to take over and I'll show you a more recent take of my tank (my setup sounds similar to yours). I know this algae stuff is a disappointment, but its manageable as I have learned. Bet your Tang has a full tummy much of the time!
Just curious, what is your 35g bf setup right now? BTW, I envy the East States. As far as I can tell this is a bigger hobby over there than it is here on the West coast. I'm looking into a PNWMAS over here about an hour or so from my home, I would like to get more involve with my SW community over here, just wish there were more of us over here.
I added a few Chromis to my tank the other day, they're not the brightest fish. Couple ended up in the belly's of my Anemones for a snack. If you see my Anemones you'll understand their fate. That was my bad.
Take care, look forward to following along. Any pics of your 35g bf?
Hi Brian, welcome to the thread.
Building the acrylic sump has been a lot of fun and very rewarding. I am glad you found an easy supply for acrylic. You can really do amazing stuff with it.
My old tank suffers (or I should say suffered since I just took it down) from poor filtration and I realized very small number of "cows" as Melev pointed out.
Unfortunately the tank was a commercial setup with a stand without enough space to accomodate even a small sump. BF was through about 40lb of live rocks and live sand. A remora C skimmer had the task of exporting nutrients. I tried to keep bioload down. My fish are a 2.5" yellow tang and a couple of mated clown fish (recently just one male widow as the female died).
I also have two anemones: a green bubble tip that is the clownfisk home and a florida pink tip anemone.
Both of these anemones grew quite large and I believe this is the reason the bioload overpowered my biological and nutrient export capability. This has lead to high nitrates 10-20 ppm and later phosphate. The overgrowth of hair algae all over I believe has choked the ability of the live rocks to do their job as biological filter, however I never had measurable ammonia or nitrites.
Just yesterday I took down this tank, transferred the fish, anemones and remaining snails and hermit crabs to a temporary 20g tank.
The rocks have been scrubbed clean of hair algae and are in a vat with saltwater and a powerhead. I am keeping this in the dark and I'll let it cook for a while.
The solution for my algae problem will be the new tank. Because of this past experience with marginal filtration I kind of oversized thinks on the new 180g. A large sump, a skimmer rated for a bigger tank (ER RS250 - 8"wide and 30" tall) that I may convert into a recirculating skimmer, plus carbon, PO4 and Ca reactors.
I also wanted plenty of flow, so the new tank is going to have a closed loop with an ocean motions 4 way to alternate flow. The pumps are 2 Reeflo darts one for the filtration and one for the CL
I am looking forward to see your 180g build thread
