Tank upgrade

[KyleV]

I came into a great deal on the Oceanic 33 gallon cube. So is it worth it to upgrade a 22 cube to a 33 cube for a seahorse tank?

I know that it is 33% more water volume but since the new tank would be placed in the same spot I'd be affraid of the transfer causing a spike and killing everything.

Is there a way to do an inplace upgrade without having devistating effects.

Just reuse all your old water and live rock/sand and you shouldn't have a problem. I went from a 29 to a 58 with no problems.

add new water to old water and presto, water change without changing water

funny but true

I put new sand, some LR and some water from a change into a nano, and added four fish the same day. We still have them.

How much sand do you have? How much live rock?

[KyleV]

30 pounds of sand and 40 pounds of rock

I think transfering the sand is debatable... because stirring a deep sand bed could be a hazard it releases a lot of trapped gases or bad stuff into the water doesn't it?

I've had great success rinsing/cleaning the sand bed, using 90% new water and same liverock.
Your water visibility will be great within hours and everything will be happy and healthy.

If you rinse the sand first you should be ok. It won't take ten minutes to rinse 40lbs. You could reseed the sand if you saved a cup or so of the old unwashed sand. I just did the exact same thing moving a nano to a 20gallon. 50/50 old to new water. fish didn't even notice. We have 33 cube for our horses and its great! Congratulations.

you could borrow that HIATT torpedo and have no worries. :) it's chew through any kicked up amonia like there was no tomorrow.

course in order to get the right flow through it you might be making sand soup out of your tank...

personally, I wuold go w/ a new sand bed.

just rinse the old sand to look like new. If you need for sand just go buy some seeing as though you wont need as much. I transfered my 29 into a 58 with no problem.

[KyleV]

Thanks for all the advise. I rinsed half of it and moved everything...so far so good. Used some water and rock from my 100 gallon also.

I transfered my 75 gallon to a 240 gallon about 7 weeks ago. I transferred all of the sand from the 75 (about 100 lbs or so) and rinsed of about 150 lbs. of sand that I picked up from Prof. Mixed it all together in the 240, transfered all the rock, water, fish/corals. Did water tests everyday for two weeks. No probs at all here. The only thing I did ( to make me feel somewhat safe) make sure was to not do a water change for about 5 weeks to build up for this large water top off. You should be o.k. , gl
