In deep water.

Lucky!!!

For filtration you could use an Aquaclear. For the skimmer you could use a BakPak, Remora, etc.

For the drugs, I like arsenic. Its cheap, and it shuts them up for good. But, there are plenty of good "medicines" available, its sort of a matter of personal preference. Would you like me to name more?

In my 135g I use an Iwaki wmd40rlxt ( High flow 22.4 gpm 15.4 max head) for return with an overflow and an Iwaki wmd20rlxt ( High flow 13.7 gpm 8.2 max head) powering my skimmer along with an 1140 powerhead for a harder flow zone ( for the coral that demand high flow) and to take air out of my overflow. I have never had a single problem with these and they have been known to run awhile dry without hurting them, for those mishaps. Both of these pumps are run through my sump that was specialy made with skimmer incorporated for my filtration.

All this seems to provide me with enough flow along with the fact I have a *refugium* tank that also flows water through it and back into my tank, though that flow is minimul.

You probably know what kind of flow rates or turnover rate you need, it is just a matter of how you want it set up (external pumps or internal) and how much you wanna spend, both those pumps are anywhere from $210 on the 40rlxt to $160 and around $150 for the 20rlxt or less. The hardest part is determining the head pressure you need (talk to your LFS and describe your needs and what you want to accomplish) and the type of return you want, I have a 1" pipe with holes along it put against the back glass pane (Spray Bar) for full tank water movement. You can get fancier and spend more money and go as far as having alternating return heads on each side of the tank for randomized water flow simulating more of a current if you so wished. And with external you have to have some sort of overflow, be it predrilled aquarium or a purchased overflow.

Anyhow the possibilities are endless with external, which I like, compared to internal (cheaper) without having to be a part time plumber but having your return and water flow almost already determined for you.

First off, Awesome find...

What I can say to do for calming a spouse is make as little as possible come out of the wallet... What I do is take money from some sales and apply it to it. For example, I recently sold some stuff on ebay totaling about $250 in my pocket after expenses. The I sold one of my car amps for $50. That helped me calm the wife. (in your case it'll calm the bf) You could try selling the 55g tank and use that money, but I think it would be better built into a custom stand and used for a large sump.

Anyway, sell some stuff and buy some stuff...

GJ on the find... If you want to sell it let me know :joke:

Use a sump IMHO for filtration, but there are several options for you to look into, but with that large of a tank you will need plenty of water turnover in a filtration system that canisters, I feel anyhow, won't produce as well.

Then again opinions are like.. EYE holes, everyone has 'em.

How about ruining everything for a while and making the 55 into a sump for the 150?

Form follows function. This tank can be an expensive or low cost deal, the animals you desire to keep will determine this.
What do you want to keep? please be specific.
