My 300 gallon acrylic tank

[steve the plumb]

I do miss this tank but the 300 will be so nice

[Acrylics]

Personally, I'd count on 1000gph +/- through the overflow. I'd run the water to about 1/2" below the top of the tank so just about to the top of the teeth.
Tank looks to be 1/2" material, maybe thicker if my eyes are tricking me.
T5 lighting would be fine, no problem.
Why would y need more room between the slots and top of the tank? (just curious)

The tank looks great. Who did you order it from?

[steve the plumb]

It looks to be 1/2" thick.I thought at that size tank it was 3/4" acrylic.I will have to take a measurement.I was told the tank would be 3/4" thick.I guess I was thinking of my old tank where I had a hob overflow and a good 1 1/2" space between the teeth and the top of the tank.I do admit this overflow is much larger .I was also thinking what if the overflow ever blocked I wouldn't have much space for error.This happened with my old tank(u tubes)The kit came with sponges I am not sure I will use them since they get dirty.I will have to either get a straight pipe with a strainer or do the dorso thing.I will have to see how much room I have in there.I think if I wanted there are 4 holes in the overflow box.the other holes are 1 1/4" so I could also use those holes to direct feed a skimmer but I think I will enlarge them to put 3/4" bulkheads and then enlarge the holes on the side of the overflow(they are 3/4" will enlarge them to fit a 1/2" bulkhead) so I can have my return line in my overflow.

[steve the plumb]

this hole on the side of the overflow is 3/4" I should enlarge the hole to fit a bulkhead.I could just run a pipe threw it but it won't look as nice.I also plan to use lock line so I can aim it around and adjust height

congrats steve on getting the pics uploaded and tank. it look very nice, how big are the openings on top and the one pc eurobrace should be very strong.

[steve the plumb]

spike the tank was made by Innovative Plastics.Its very clean and well built.I never had an acrylic tank so I am more used to more room on the top of the tank.I keep think the tank will fill up so close to the top that the fish will jump out.I will have to get some kind of magnet to clean the glass.Acrylic it also came with covers for the holes on top cover,should I use them?I am thinking I will get alot of slat creep on the top part of the tank will I have enough space to clean it.

i would try to get a bulkhead that will fit, and not risk cracking the plexiglass. IMO try not to run a pvc through the hole.

[steve the plumb]

I know a 1 1/4'threaded adapter will fit in there.I got one with the tank.Its either 1" or 1 1/4" but the thought of putting a male adapter with an o-ring and having water run in it didn't pleas me to well.Plus it will be under pressure.The guy who built the tank is going to call me and explain what hole size is for what.I was going to use a hole saw I don't think it will crack but if you think it may crack I won't do it.I looked on the internet and most bulkheads 1/2 and 3/4 needed larger holes than what the guy made me.My old fitting from my hob fit in the hole its either 1" or 1 1/4" but the thought of putting a return pump on a line without glue might be a disaster waiting to happen.I will take more pics of the holes.

[steve the plumb]

there is 6 " all around the tank

[steve the plumb]

This is the tank opening

Width

[steve the plumb]

This should be the width of the larger opening

[steve the plumb]

Its a 1" male adpt that fits in the hole

[steve the plumb]

Holes for over flows the smaller holes fit the 1" fitting

[steve the plumb]

I should have taken a mesurement of the overflow box.I forgot to do that.

[cbui2]

worst case scenario, using a dremel to enlarge the hole will be safe then hole saw. since the hole has already been drilled, and then using another hole saw to open that up is kind of difficult without a drill bit as a guide IMO. also with the hole so close to the very top making it very fragile and looks to me overflow box are about 3/8" thick. what the size of the opening top to bottom? i see one is 19.5"L. the reason why i'm asking is to figure out what lighting fixtures can fit so they wont be directly on top of your eurobracing.

[steve the plumb]

I was going to place a piece of wood inside and use a the drill bit on the hole saw to guide me.I have done that before but not on an acrylic tank.I can use a dremel it will be safer.The larger hole is 20 x20 not exact on mesurement the center hole is 20x12
.The problem is if I get a 4 ft fixture it falls right in the middle of the center hole.I may hang the lights 4 inches off the tank and have them on a rail so I can move them to work on the tank.I don't think I can have a T5 fixture right on the tank or can I but it would have to be smaller.It was kind of late so I didn't take exact pics of the top oppening

[cbui2]

thats nice size opening, on mine i have VHO directly over the top of the acrylic which should be ok IMO, but MH is inside the opening. how big was the last display it look very nice.

[steve the plumb]

My last display tank you mean?150 gal.I took some measurements. both larger side openings are 24"x12" they start after 6 " from end of tank.there is basically 6" all around the tank.There are 2 large openings.the middle opening is 24"x18" there is 8" inbetween the two lager openings.So 8" on both sides exact.The openings are made to be inline with everything so it does have a nice balance.The overflow is 1/8" thick so to drill those 2 holes may be a bit hard they might crack.the overflow is 5"x14 1/2" and its 6" away from the center hole(20"x12" hole the back of the opening is 6" away from overflow)I think hardest part will be the 3/4" hole in the overflow at 1/8" thick it won't be easy to enlarge plus its a tight squeeze.I think the best way is the dremel.

[steve the plumb]

would I be able to use a Tunze wave box in my tank?I am thinking I won't have enough of a gap at the top.The water will spill over.

[cbui2]

sorry steve, but nothing on tunze in my system so i cant give any advice on that one. will you be working on the stand this weekend?
